More Ravages of Time

I have two acrylic body pencils made by a pen turner. The first (top, 2-piece) one he made for general sale and the second (bottom, Duofold style) was commissioned by myself.
I really liked both these mechanical pencils when I bought them. Now... not so much.
I must admit I was very surprised to see what has happened to these mechanical pencils over time. Firstly the gold fittings are in excellent condition, as good as the day I first saw them. I really never expected much from the gold trims and would not really have been surprised to see some corrosion showing through. But, as I said, nothing. They are as good as the day they were made. So what has gone wrong and surprised me? Well the acrylic bodies have deteriorated. Unfortunately you can’t see it in the images, but you can see and feel it in real life. The acrylic has developed small ridges / waves / indents / dimples… whatever you like to call them. The Duofold style pencil is definitely worse than the other, but both have the same deterioration. The Duofold style pencil acrylic body also has an actual delamination in one part down where it joins the tip.
Ouch! Nasty sharp little protruding delamination.
The two piece body pencil also has another problem. The two halves have started to separate so that there is now a 1mm gap between the bodies and the centre joining ring.

These two pencils are about 9 years old and I thought I would contact the maker to get his comments. I wasn’t really complaining, just giving him feedback, and he replied quite promptly. He is no longer in the pen game, the quake of 2011 put an end to his business, and he is now retired. Nevertheless he was interested to hear from me and had a few comments in reply, slightly paraphrased below.
The issue with the ridging etc sometimes occurs right from the outset. It seems to be caused by the ribbons that are inserted in the acrylic pour to make the swirls. The technique involves two separate consistencies of mix, one always harder than the other. The gaps in the two-piece pencil centre are the brass inner tubing slipping on the joining knuckle (possibly from heat fluctuations). The pencils have a solid brass tube skeleton and are pressed together. Consequently they are held in place by friction only. I can't say what may have caused the delamination of the acrylic near the tip. Atmospheric humidity maybe?
It’s disappointing to hear the acrylic wave problem basically being a known-problem. I doubt the modern high end luxury manufacturers who use marbled acrylics have the same problem. I can confirm that my marbled Parker Duofold Centennial doesn’t have this problem, nor do my vintage Conway Stewarts.

In the old days I know that a couple of pen turners used to be regular readers of this blog, so I would be very interested to hear any comments from turners, or from readers who have had similar problems.

Don’t worry, this is last planned post about the Ravages of Time.

Old Friends

A couple of old friends from the desk, still going strong, but probably not for much longer :)


Jeopardy is updated, now down to 655. And from the comment archive, this gem put a smile on my face.
Maybe we collectors are the villains here - why does any of us need so many pencils? (My wife told me to say that. I'd like to know why any one with only two feet needs that many shoes.)

Spoke Design Interview

Spoke Design Mechanical Pencils

I first became aware of Spoke Design back in July 2012 when they launched a Kickstarter campaign for a mechanical pencil. The campaign was a success with 318 backers funding US $16,782. That was the original Spoke mechanical pencil, Spoke 1, and now they are onto the Spoke 4 mechanical pencil. I have recently been in touch with Brian from Spoke and thought it would be interesting to do an interview with him. Happily, Brian agreed.
****
1 - So, Brian, tell us a little about yourself and Spoke Design.
I’m a mechanical design engineer and I live in Charlotte, North Carolina USA.  I have spent my whole career in new product development.  The majority of my career has been working for corporations in various industries (telcom, barcode equipment, security devices).  The bulk of my experience is actually in plastic part and product design, but I am a hobby woodworker and a very hobby machinist. I have been working full-time on my own for over a year now.  The Spoke brand is a part of the product design and development company I run with my brother Dan… aptly named Conti-Bros, Inc.  It’s a small enterprise… it’s just us two and Dan is part-time.

2 - I imagine as a mechanical design engineer you have used a pencil or two throughout your career?
Absolutely… I sketch out ideas constantly, so pencils are my preference for that.  I’ve always been a user and fan of the Pentel Sharp pencils… probably because they have been somewhat of a standard throughout the years.  I’d say I use .5mm most often… and I prefer 2B lead.

3 - Let’s quickly go through some history. Spoke 1…. Was it a case of one day you were just sitting there and thought “I want to design and make a good mechanical pencil and sell it to some people.” So you did? Perhaps though there was a little bit more to it than that, a long evolutionary process?
Years ago I was browsing online and I ran across a news article about how this new website called Kickstarter had just had their first million dollar project (a machined iphone stand I think).  I had never heard of Kickstarter or crowdfunding… when I looked up the site I became fascinated with how it could be used to find, test, or create a market for new unique products.  I had to give it a try.  My first two submissions were actually rejected by Kickstarter… they were designs for ‘active foot rests’.  As I spent so much time at my desk, I had made prototypes of these for myself to allow some ‘fidgeting’ with my feet.  Back then, Kickstarter didn’t allow ‘exercise products’ so they rejected my submissions (they have since changed their policy and others have successfully funded several similar products to what I had originally submitted).  Undeterred, I noticed a few machined pens really becoming popular on Kickstarter… so I decided I could try to see if there was a similar interest for a machined body mechanical pencil… my preferred sketching instrument.

Many of the pens on Kickstarter are simply ‘minimal’ cylinders… largely indistinguishable from each other.  My goal was to make something very distinct and immediately recognizable by its design… after lots of sketching and prototyping… I settled on long slot features to be the signature design element.  The Spoke name seemed a natural description of these features.  The project was a moderate success on Kickstarter (after all pens are a much bigger market versus mechanical pencils), and that’s how Spoke got started.

4 - Spoke 1 was obviously a success by whatever measures you personally use because you have carried on and now there is Spoke 4. What’s the one big thing you learned from the Spoke 1 campaign? By the way, what do you call the original Spoke mechanical pencil now there’s more than one?
Spoke 1, Spoke Original – I’ve called it both.  From the outset, I had planned to do versions of the pencil… the initial pencil is designated by a machined ‘dot’ on its end… so I also refer to it as Spoke Pencil single dot.
There were three big takeaways from Spoke 1 (single dot)…

First, while I can make various types of prototypes, for production quantities, I had to develop a capable supply chain for my intricately machined and anodized parts.  It’s fun creating relationships with machine shops and working together to produce cool parts.  It’s always exciting and fulfilling to take something from sketch to physical product, but volume manufacturing has its own set of challenges and learnings as well.

Secondly, the initial project provided an introduction to the Kickstarter system.  Crowdfunding is a unique process with lots of things to learn. Since the original Spoke Pencil we’ve used Kickstarter to fund several other products (most notably a brand of magnetic products under the brand of Strong Like Bull Magnets.

The third thing I’ve learned is that selling products online is quite difficult.  As a design engineer, I had little experience with e-commerce, marketing, website creation, etc.   I’ve since learned quite a bit through the years… and continue to work on this area.

5 - With perfect hindsight, what would you have done differently?
While I’ve learned a lot along the way and have definitely had some missteps… those things were part of the journey so to speak.  Overall I’m happy with the path I took.

6 - The wood turning folk have always had pen and pencil mechanisms readily available for their use. One of the intriguing features of Spoke 1 was your use of Pentel P205 mechanisms. I’m imagining you buying a few hundred Pentel’s from a local store, ripping their mechanisms out (sacrilege!) and assembling them into your Spoke bodies. Is that what actually happened? Where are you sourcing your pencil mechanisms from now?
I buy the standard pencils wholesale from a distributor.  The great thing about the Pentel P200 series is that they are readily disassemble-able.  This makes it easy for me to utilize the mechanism and also easy for customers to get ‘replacement parts’ if ever needed.

7 - Tell us about Spoke 1, 2, 3 and 4. What’s different about them? What did you learn from each and think you would like to try on the next variant? Has feedback from users influenced you much?

Spoke Pencil (single dot)… the original.  A one piece pencil body utilizing the P200 series mechanism.  The body is machined from aluminium, has a swooping profile with hexagonal cross section and of course the six signature slots.  There’s quite a bit of machining going on there.  It was funded on Kickstarter and now retired from sale, although I do have a few reworked pencils I sell occasionally.

Spoke Pencil 2 (double dot).  Spoke 2 was a follow up design that was more a refinement than new design. The main change was a slightly smaller profile and a bit narrower slots.  It was released on my website and not a Kickstarter project.  Spoke 2 is now retired from sale, although again, I do have a few reworked pencils I put for sale occasionally.

Then there was Spoke Inverse.  The inverse was a shift to a more simple cylindrical design, with the main feature being an inverted taper in the grip area.  Inverse was a smaller pencil altogether, using the Pentel P225 mechanism (since discontinued).  It was released on my website only.  Inverse is retired from sale, although I do have a few reworked pencils I sell occasionally.

Spoke Model 3 (triple dot).  The model 3 was a big departure in design and material. I decided to go with Titanium.  Design-wise it has a stepped profile with circular cross sections, bevelled edge slots, and a heavily grooved grip.  The model 3 proved to be quite difficult to machine… and ultimately only 100 were made.  Model 3 was released on my website… and is now sold out.

Spoke 4.  By this point I had received a good amount of feedback and requests from customers for various materials, colors, and grip sizes.  There’s no one perfect pencil configuration to satisfy everyone, but I thought it would be unique to offer a degree of customization to try and address common requests.  The solution was a two piece body design in order to provide a range of material, color, and size options to customers.  This level of customization has proven to be popular.  The model 4 is an interesting pencil in that depending on configuration it can vary significantly in how it looks and feels… many customers order 2 or 3 and mix up their order configurations a good bit.  I’ve decided to make the model 4 a ‘standard’ pencil with no plans to retire it any time soon.  In fact, I plan to add some additional colors.

8 - As you have mentioned, the Spoke 4 mechanical pencil is a pick ‘n’ mix of 5 different grips, each in 2 diameters, and 5 different barrels, so that’s 50 combinations. Which combination if your personal favourite? Is there any clear preference from customers for grip diameter, grip material or barrel colour?
I have several pencils on my desk, so I do mix up what I use quite a bit.  Overall I probably favour the smaller diameter 8.3mm grip in Titanium with a blue barrel.  The titanium moves the balance point closer to the tip while not adding too much overall weight, and the blue provides a nice contrast to the spoke grooves.  As for customers, the classic look of Titanium with a black anodized barrel is most popular.  Orders are generally split pretty evenly between the 8.3mm and 9.2mm grip diameters.  While the dimensional difference seems quite small… the result is a big difference in feel.

9 - You have offered your various Spoke pencils in 0.5, 0.7 and 0.9mm lead sizes. What has been the most popular?
The .5mm is the most popular… I’d say half of all orders are for .5mm with the remainder spilt pretty evenly between .7mm and .9mm.

10 - You have also branched out into some other stationery related items. I guess anything on your desk is fair game?
I have quite a diverse background in the types of products I have developed.  Under Spoke, I’ve done a machined ring holder and more recently a machined note holder… both on Kickstarter. While I do enjoy the challenge of working on a variety of product categories, I really enjoy working on writing instruments… and expect to keep releasing new Spoke designs going forward.

11 - Okay, well thanks for telling us this Brian. All the best for the future… so Spoke 5 is already in your thoughts?
Yes, Spoke 5 is coming!  I’m at the prototype stage and hopefully it’ll be ready to go in the next month or so!  However, the model 5 is more exploration of the spoke design… not a model 4 replacement.

I will leave you another nice photo supplied by Brian.

Spoke 4 Mechanical Pencil Review

Spoke 4 Mechanical Pencil Review

Long-time readers of this blog may well remember the original Spoke Design mechanical pencil from back in 2012. Well, the years have gone by and Spoke Design are now up to Spoke 4. They are still sticking to their origins of exploring designs with a spoke theme and using the Pentel P200 Sharp mechanical pencil mechanism.
spoke 4 mechanical pencils

The Spoke 4 mechanical pencil is a mix and match two piece design. You choose what combination of the two grip diameters, each available in five different materials, the five different barrel colours and the three different lead sizes you want, and Spoke assemble that mixture to make your pencil.
• Grip: 8.3mm and 9.2mm diameters
• Grip Materials: Aluminium (Anodized Black & Grey), Titanium, Brass, Stainless Steel
• Anodized Aluminium Barrel, colours:  Black, Blue, Red, Grey, Silver
• Lead Size: 0.5 / 0.7 / 0.9mm
The assembly is permanent; you cannot later undo and swap combinations around.

Learning from my mistake with the original Spoke pencil I decided to go for a nice bright red barrel. The 9.2mm stainless steel grip and 0.5mm lead seemed like the options to suit me so that’s the pencil I have. However, Spoke generously threw another pencil into the box when they sent my order, so I also have a 8.3mm titanium grip blue barrel 0.5mm pencil as well.
red and black spoke 4

Right then, first off the Spoke 4 mechanical pencil in my two colour combinations is a nice bright visually pleasing writing instrument. The black slots, sorry spokes, make a particularly nice contrast with the red bodied pencil. I sometimes thought that the bright chrome of the pencil tip did not quite go with the duller stainless steel or titanium grips, but then other times I thought I was just being stupid.

The Spoke 4 is lighter than I anticipated. The blue pencil weighs in at 18 grams and the red at 25 grams. In the hand you can notice that difference in weight, but what you really notice is the difference in balance.  The 9.2mm stainless steel grip moves the centre of gravity about 10mm towards the tip compared to the titanium. That may not sound like much but that extra weight and lower balance is definitely noticeable in the hand. The 0.9mm difference in grip diameters might also seem minor but again it is definitely noticeable in the hand. Being able to use and compare two non-identical twin pencils like these has been very interesting.
spoke 4 grip sections

The grip has concentric rings cut into it. As expected they give a positive vertical grip but allow for quick easy rotation. All bets are off though if you live in, shall we say, a hot sweaty humid environment.

Given my recent ramblings on the durability of mechanical pencils I think I should make it clear that the Spoke 4 is an all metal mechanical pencil, and in particular that the titanium and stainless steel grips are machined from solid metal. There’s no PVD coatings here, so those of you in the space game can rest easy knowing that your titanium grip will undoubtedly prove resistant to hypertrophic alien slugs and their corrosive slime.

With the mechanical pencil mechanism being taken from a Pentel P205 Sharp, the Spoke 4 has a fixed 4mm lead sleeve and so is suitable for draughting but is not pocket safe. There is also of course the emergency eraser under the push top cap.

Eagle-eyed readers will have noticed the lack of a pocket clip in the various photos of the Spoke 4.  Now, that in itself is not too much of a problem for me personally. Indeed, some pencils come with removable pocket clips to suit those who find them an impediment, but the barrel of the Spoke 4 pencil is round, and the spoke sections are depressed into the barrel, so when you rest the pencil on your desk it can roll, and there is no pocket clip to stop it. Yes, I know there is the desk dock, but that may not travel with you to the meeting room, and I prefer to just put my pencil down anywhere rather than having to specifically place it somewhere. That then is a significant negative for me. Great pencil, love the mix and match options… please stop it from rolling around on my desk.

Spoke Design have always gone the extra mile and their mechanical pencil comes with a tube of replacement erasers, a refill tube of Pentel leads and a desk dock. The dock works well and is made from acetal plastic so it won’t mark your pencil grip but will be very durable and hard wearing itself.

In my review of the Spoke 1 mechanical pencil I suggested a small number of minor points for improvement. This review would not be complete without revisiting those. So, back then my comments were
• This is a great pencil, be proud, put your brand name on it. I would also love to see "USA" on it too.
• Spoke 4 = Spoke yes, USA no.
• The pencil stand is a great idea and works really well. I wonder though that over time the metal on metal contact with the pencil tip section may lead to some wear on both. Perhaps a plastic insert in the stand is worth considering.
• Spoke 4 = The dock is now much larger and made from hard wearing acetal plastic.
• The edges of the hexagonal body are just a little sharp for me. Some more rumbling or perhaps some deliberate rounding in the finger grip zone would be in order.
• Spoke 4 = No uncomfortable or sharp edges to be found anywhere
• In the right light, at the right angle, with good eyesight... boy, I'm being very picky here... you can see some very minor tool marks. A little more rumbling might help.
• Spoke 4 = Picky, picky…Spoke 4 looks good, no tool marks in sight.

Overall then the Spoke 4 is a very good mechanical pencil which you should seriously consider adding to your collection.

•    Best Points – It looks great and you can customize to suit yourself.
•    Not So Good Points – It rolls when you put it down.
•    Price Range – Mid
•    Does this pencil make it into the Top 5? – No

Dimensions – Length 142mm, diameter 10.5mm body. Balance point for stainless steel grip variant about 60 mm up from the tip and 70mm for titanium grip variant.

Caran d'Ache Ecridor Yacht Club Mechanical Pencil

Caran d’Ache Ecridor Yacht Club

caran d'ache ecridor yacht club mechanical pencil


Those marketing folk always have to tempt us. Most weeks I get out on the water for a quick sail and so nautical themed objects have some allure for me. I like Swiss Army knives and I eventually succumbed to temptation and bought the Victorinox Skipper, and recently I gave into temptation again and got a Caran d’Ache Ecridor Yacht Club 0.7mm mechanical pencil.

Two Swiss classics

I have previously posted about my two other Ecridors, the standard Ecridor and the Artiste. The Ecridor Yacht Club is available in fountain pen, ballpoint pen and rollerball, as well as my mechanical pencil format. These days Ecridors are palladium coated rather the rhodium coating used in the past.

The engraving on the body is what makes the Ecridor Yacht Club different from other Ecridors. The guilloche engraving features two nautical themes. Firstly a rope motif to link with yachting, and the main feature which is the wording “Caran d’Ache” engraved on the body in nautical flags.

Ropes and flags

For those of you who are not aware of maritime signal flags, in the old days before radio, ships could communicate with each other by flying flags that had meanings. Nowadays flags are still officially used and there is an internationally agreed set of flags that represent numbers and letters so messages can be spelled out, as well as specific individual flags or combinations having a specific meaning. For example flying a black and yellow quadrisection flag means the ship is quarantined and should not be approached. Of course you may want to send private messages, e.g. instructions to your battle fleet without allowing the enemy commanders to understand your signals, so navies historically had flag codes as well, with a code book of common messages and words and the corresponding flags to fly to represent them.

I leave you then with arguably the most famous maritime message ever sent.

Ohto Words SP10-A Mechanical Pencil Review

Ohto Words SP-10A Mechanical Pencil

I believe this pencil has been discontinued in the not too distant past but it’s still available from a number of retailers. So even though it is discontinued I want to review it simply because it looks so nice. Pure eye-candy. There’s just something about the way it looks that I find extremely attractive.
ohto words sp10-a mechanical pencil

The metal body is available in a number of different lustrous coloured finishes, mine, as you can see, is blue.

Weighing in at 18gm the Ohto Words is a little lighter than I expected. I feel the weight somehow does not quite go with the visual beauty and a slightly heavier construction would enhance the overall package.
ohto words mechanical pencil cap posted

Ohto Words is a capped mechanical pencil, and you can use it with the cap posted or not. Personally, when writing, I prefer the look of it in hand with the cap posted…the long sleek elegant look. The cap is a very positive push fit onto either end of the main body.

I always like to see a mechanical pencil comprehensively marked with brand, model name and number, and Ohto usually do, as they have with Words.

The pocket clip is very sturdy and stiff, probably too stiff. You will certainly have to put in some effort to clip it to something. But its’ size, shape and colour combine with the cap section to make a truly aesthetically pleasing sight.
ohto words mechanical pencil capped

The lead sleeve is 2mm long and fixed, but of course the cap means this is a pocket safe mechanical pencil. The lead advance is a push top ratchet mechanism, operated by the rounded end piece of the main body, with or without the cap section posted on the body. Ten clicks will advance about 7mm of lead. You access the lead magazine by unscrewing the body and removing the otherwise hidden emergency eraser with lead jam clearance rod.

The grip section is rubber with fine grooves running lengthwise rather than circular around the body. The rubber grip does feel quite “grippy” so that is good, but I just hope that Ohto have used a rubber formulation that will stand the test of time rather than degrade over a decade or two. The fine grooves in the grip do catch the light and add to the appearance of the pencil.
ohto words rubber grip

I said at the beginning that this pencil is eye-candy, but is also a great pencil. It is true threat to the Throne of Sharp Kerry. Ohto Words mechanical pencil – if you like a pretty pencil, then buy one now while you still can. It's a great deal at that price point.

•    Best Points – Did I mention how good it looks?
•    Not So Good Points – The pocket clip is too strong.
•    Price Range – Low
•    Does this pencil make it into the Top 5? – This is a really tough call, but after much deliberation I have decided “No”… except for its looks.

Dimensions – Length 125mm main body only and 150mm with cap posted, diameter 8mm across the grip section. Balance point about 50mm up from the tip without cap.
