Failure?

Failure!!

This is actually a posting that isn’t; an idea that didn’t work out. Still, it seemed like such a good idea at the time, that I feel compelled to write something, even if it’s basically nothing. Understand?

One day a thought popped into my head, “Just what pencil does Uncle Sam use?” Even better, “What mechanical pencil does the US Army use?” Surely there was a story here.

Well it turns out that as far as I can tell (from a long way away), there isn’t really any story here. From a few US folk I’ve asked, and the little I could find on the web, it appears that these days things have changed, that the Army doesn’t do big national deals on this sort of thing. They pretty much shop where you and I do, but they probably get the big bulk-buyer discount price, although apparently there are some nifty army camouflage pencils. But basically no story here.

So I changed tack a little and searched around for some pencil and local military links. Again not much of a relationship, although I did find a few snippets like this:

Major-General Horatio Gordon Robley, the “Soldier with a Pencil” who served with the British Army here in NZ in the mid-1860’s during the New Zealand Wars. He made many finely detailed drawings of colonial and Maori life which are an important historical archive. This is the front cover of a small publication of some of his drawings - it’s the facial tattoo of a Maori chief.

Another link I liked was of a comic story from the trenches of France / Belgium in World War One. A little light-hearted NZ colonial humour directed at the ‘superior minds’ of the (British) commanders, with their fancy pencils, multiplication tables and ready-reckoners.

“Hush!” said an orderly who entered stealthily. "Do not disturb him yet. He is engaged upon a mathematical calculation.""Good Lord!” I said. “Why does he tax his brains with such difficult work?”
It appeared that he was busy with a report to the Corps Commander. His pencil was working furiously. The problem was this: If two mules can draw two hundredweight of patĂ© de foie gras on a trench tramway two feet wide with a grade of one in a hundred on a curve of one in fifty as laid down by a New Zealand engineer, what will be the weight of the two mules and the name of the muleteer? "Upon the solution of that problem," whispered the orderly, “will depend the feeding and the equipment of this Army for the next three years."

Staedtler Mars Micro Carbon Lead Review

Staedtler Mars Micro Carbon Lead Review

In the 2006 Lead Cup, Staedtler Mars Micro Carbon Leads were eliminated in pool play - they had a tough draw as the eventual Cup winner, Pentel Ain, was in their pool. Staedtler finished second in their pool but missed out advancing to the next round on a points count-back. Here in my part of the world Staedtler leads are quite common, so a review seems in order.

Currently the Staedtler website lists the following size and hardness options for Mars Micro Carbon leads.
0.3mm = B, HB, H, 2H.
0.5mm = 2B, B, F, HB, H, 2H, 3H.
0.7mm = 2B, B, HB, H, 2H.
0.9mm = B, HB.
For the purpose of this review I’ll be sticking to 0.5mm, 2B to 2H as per the line up below. Mars Micro Carbon leads come in clear plastic rectangular container of 12 leads. They have a simple push fit stopper, which once removed allows the leads to pour out. The idea behind this is that many of the Staedtler mechanical pencils have lead refill magazines that will take 12 lead refill sticks at a time and the neck of the tube fits into the top of the pencils refill magazine, making for a quick easy top up. The size label is colour coded to match the lead magazine on Staedtlers pencils, e.g. note how the “0.5mm H” part of the label is a reddy-brown colour, and Staedtlers 0.5mm technical pencils all have that same colour lead magazine. For 0.3mm pencils and leads the colour is yellow, blue for 0.7mm, etc. This is all according to an ISO standard for the colour coding of drawing instruments by line widths. The refill tubes and their labelling are clean and functional, but nothing “fancy” in comparison to some of their (Asian) competitors. The reverse side has a barcode and some recycling symbology. I note that they all state “Made in Germany”.

Now it’s time to put graphite to paper, try a few things and do a comparison or two to the reigning champions, Pentel Ain.

The very first thing I noticed was the lead diameter issue covered in my earlier posting. These Staedtler leads certainly are prone to sliding a little bit through the mechanisms of some non-Staedtler pencils. Let’s have a look at the blackness range of 2B through to 2H. As usual, it’s rather hard to tell one grade from the next one on the scale, but you can see a difference over the full spectrum. One thing I did note was that H definitely felt harder than 2H when I was writing with it. HB was the first grade that felt “smooth”. The harder grades all felt “hard”, you could feel the paper grinding lead off the stick. HB was the first grade that felt smooth. So, there was a clear difference in the “feel” of the lead when changing from F to HB. There was also a noticeable change in feel from B to 2B.

Now let’s do some comparison to Pentel Ain. Ain 2H is definitely harder than Staedtler 2H, though there is not really any difference in blackness. In HB the two brands are fairly similar in hardness, but Staedtler is slightly darker. The story is the same in 2B.

One would assume that Staedtler would tailor their Mars Plastic eraser to suit their pencil leads. So, onto a spot of erasing. Well both 2H’s erased easily and completely, but afterwards you could clearly see how much more the Ain 2H had indented into the paper. There was effectively no difference between the two HB’s. With the 2B’s it was close, a little initial smearing but then both erased reasonably well. However, I do have to say that the Staedtler 2B left behind a little bit more of a residual grey smear than the Pentel Ain did.

I won’t pass judgement on whether the leads should smear easily or not, but not surprisingly, smearability definitely increased as the grade got softer. So 2B smeared much more than 2H. Both Staedtler and Ain were fairly similar in smearability, but if forced to choose I would say that Staedtler smeared just a little more than Pentel Ain.

I guess the one trait that is not debatable is strength. Stronger is better, at least until you reach a point where the leads don’t break in any sort of normal use. After that, extra strength is reasonably irrelevant. Pentel Ain has an impressive reputation when it comes to strength. In 2B, Ain was a bit stronger than Staedtler, and both were clearly weaker than their HB grades. There is a huge leap in strength for Ain 2B to HB, much less of a leap for Staedtler. So Ain HB is significantly stronger then Mars Micro Carbon HB. 2H was slightly stronger than HB, but the difference between Staedtler and Pentel had again narrowed I’m not sure which was the stronger of the two brands. Overall, for Staedtler I am not sure they have reached that point of “strong enough”. I do have some occasional breakages when using Mars Micro Carbon leads. I would rate their strength as “OK” or “Acceptable” rather than as “Good” or “Outstanding” like Pentel Ain.

In closing then, Staedtler Mars Micro Carbon leads are good, but they could do with a little more strength in 0.5mm. For 0.7mm and 0.9mm I don’t think there is any issue.


As well as the containers of 12 leads, Staedtler also offer 0.5mm and 0.7mm, 2B and HB leads in a much larger container of 40 leads. This container is a push button dispenser – you push and hold the grey end cap in and leads can then pour out of the conical neckpiece one at a time. Here’s an older version of the container of 12 – it’s the same plastic moulding, just made in opaque blue rather than the current clear plastic, and the labelling is different. In particular the leads are called Mars Micrograph rather than Mars Micro carbon. The actual Staedtler part number is still the same, 250 05-Hardness.

Advertisement 3 - Alexander 1946

Here’s another ad that Glen sent me. From Colliers Magazine, 6 September 1946 advertising the “Alexander the Great” pencil. Some of the text reads “Start school with an ‘A’. ‘A’ for Alexander the Great pencil for only $1. The only all metal pencil with Long thin leads, ‘Big Inch’ adjustable eraser, Spring-steel gold plated clip” Later on we are advised to ask to also see the Commentator pen & pencil set $8.75 (no luxury tax) and the Imperator pencil $5 (plus luxury tax), which are also available in leading Canadian stores at slightly higher prices. Poor old Canadians have to pay extra.

Alexander pens…pencils ‘write around the world’.

I hadn’t previously heard of the Alexander Manufacturing Co. Bloomington, Illinois.

If you are an old-time US tax expert then tell us about "luxury tax". I suppose that depending on your marketing plan, attracting luxury tax might be a good thing. Imagine the insult of Mont Blanc or Cartier producing a fancy pencil that wasn't eligible for luxury tax.

Faber-Castell Grip Plus Mechanical Pencil Review

Faber-Castell Grip Plus Mechanical Pencil Review
The Grip Plus is a 0.7mm “Made in Japan” pencil that Faber-Castell offer worldwide. It comes in four different body colours, but only in 0.7mm lead, presumably as part of Faber-Castells assertion that the general public prefer 0.7mm lead due to breakages with 0.5mm leads. It is arguably Faber-Castells flagship pencil, as it’s the featured pencil on their websites mechanical pencil main page. I have always found the name ‘Grip Plus’ a little confusing as they also have the Grip 2011 pencil.

The Grip Plus has two prominent features – the grip as implied by its name, and its eraser. Firstly, let’s deal with the grip. The grip is a triangular rubber section. The section narrows slightly towards the tip, before flaring out at the bottom and stopping your fingers going any lower down. The compound is fairly hard with only minimal give under normal finger pressure. There are horizontal grooves cut into the rubber which definitely do further enhance the grip. Overall it’s reasonably successful. I imagine this grip would score fairly well in a test poll of the general public.

Next then we have the eraser. It appears to be a vinyl compound, about 7mm diameter and 27mm long, and is mounted in a fairly standard screw cartridge. I must admit that the screw out eraser is a welcome distraction in a boring business meeting! Twist out, twist in, twist out, twist in...how much longer is this going to drag on? The eraser compound is fairly good, erasing about as well as you would expect of a vinyl eraser.

You pull the entire eraser cartridge out to access the lead refill chamber underneath. The lead advance mechanism is a standard push top ratchet, 10 clicks advances 7mm of lead. The tip is a small cone so it’s suitable for general writing but not draughting. It is retractable for pocket safety. The lead is spring loaded to further reduce breakages. Some spring loaded or cushioned leads are rather hard to notice, but this one you can really feel the cushioning as you write. Overall, this is a very smooth-writing pencil. Personally I don’t really like the look of this pencil, but it feels OK in the hand and writes well. As I mentioned above, I imagine it would do fairly well in a test against similar competition.
  • Best Points – Good cushioning to the lead, good eraser cartridge.
  • Not So Good Points – Well, not much really, except personally I just don’t like the look of it.
  • Price Range – Low.

Dimensions – Length 139mm, diameter 13mm body. Balance point about 65mm up from the tip.

A Mini Mini

Here’s a real mini pencil. Only 65mm (2 ½ in.) long, plus a little tassel cord. I suspect it was marketed as a golf pencil back in the 1960’s or so. You twist the metal tip to advance or retract the lead.

Ohto Tasche SP-10T Mechanical Pencil Review

Ohto Tasche SP-10T Mechanical Pencil Review

All good things must come to end. Just like my holiday finished, this is the last of my holiday mini-pencil reviews. The End - but I have saved the best for last.

The Ohto Tasche SP-10T is a great pencil. First off, it looks great. With the cap on for storage, it looks compact and “useful”. Small, but not too small. Mine is a glossy dark blue colour and the strategically positioned chrome trims combine with the blue and the overall shape to produce a really great look. Opened up, with the cap posted and ready for writing it looks equally good. Stylish but purely functional.


Closed up, the Tasche is small enough to fit in most compendiums or pocketbooks. The cap system means it is totally pocket safe, and the tip is protected from any accidental damage. The pocket clip is spring loaded and is a good solid piece, not much chance of accidentally coming off whatever you clipped it to.

The Tasche has a 3mm fixed lead sleeve. Combined with 0.5mm lead size, it’s actually useable as a technical draughting pencil. Equally though it’s suitable for general writing. The grip area has no special grip enhancements. Like the rest of the pencil it is metal, but the grip section is finished with a lustrous but non-glossy finish to slightly enhance the grip characteristics. However, it’s still essentially a plain metal body so the grip will never get an “excellent” rating.

The end-cap on the body is a chrome plated screw in cap. You unscrew it to expose a small eraser, and pull the eraser to access the lead refill magazine. This is all a little bit time consuming. The eraser is definitely emergency use only. I can see the end cap rolling around the floor of the train to Brussels or the flight to LA if you were using the eraser regularly on your travels. The end-cap also has a black rubber o-ring set into it. When you post the cap onto the body to get ready to write, the o-ring guides the cap onto body and holds it there. I really the like the pneumatic, compressed air feeling as you slide the cap on or off the body. It’s like my own little piston toy – a silly, secret, little something for the engineers amongst us. Once posted, the cap is free to spin around on the body, which sometimes I like, and other times I don’t. You can actually use the pencil with the cap unposted, but in that case it is definitely a short pencil.
The lead advance mechanism is an ordinary push top ratchet mechanism. 10 clicks advances 7mm of lead. Putting the cap back on the tip to close up for the day generally activates the lead advance mechanism unless you are careful. This always annoys me. Now, I must tell the truth and say that I had a problem with the mechanism of my Tasche. The lead stopped advancing. I have a shockingly poor success rate at disassembling my pencils, they never seem to work as well after I have opened them up for “investigation”. So these days I resist temptation and only pull them apart when absolutely necessary. In this case the “lead retainer” had come loose in the tip and I managed to push it back home into position and everything was once again as it should be, so that made me feel happy.

  • Best Points – Looks good, like the cap system.
  • Not So Good Points – I would feel “picky” to list anything of consequence here.
  • Price Range – Mid.

Dimensions – With cap on front in storage position = 107mm long. With cap posted on top for writing = 139mm long. With the cap left off (unposted) = 104mm. Diameter = 8mm at grip. Balance point about 75mm up from the tip with cap posted on top for writing.

My final comment - I thoroughly recommend Ohto Tasche to you all, it is a worthy competitor to Pentel Sharp Kerry.

Good bye to Australia. Same time, same place, next year. (Maybe)
