In appearance they differ only slightly: the Koh-I-Noor has a hexagonal body while the Alvin has a round body; the Alvin has a ring between the grip and the body while the Koh-I-Noor does not; the end of the grip/beginning of the end cap and lead sleeve also differ slightly between the two; and the knurling on the grip and lead grade indicator is courser on the Alvin. But aesthetically they are definitely in the same family, if not siblings then kissin' cousins. But internally they are completely different! To see just how different please read my reviews of each pencil at Associated Content. Each is listed in the side bar just below the Alltop badge.

The Koh-I-Noor 5633
While the internal differences were striking the 2 pencils wrote very much alike as they were very close in length, girth and weight. I can't say which one that I like best. It's like having to choose between your two best girlfriends. A very difficult task to say the least. So pretty much the 2 cousins were alone in their close-but-no-cigar designs, snuggled within my pencil case for a while. I saw other pencils that seemed similar to the Koh-I-Noor, the Rotring 500 and 600 among them which is as it should be as they are owned and made by the same parent company. The Kokuyo TZ-PSP 503 is similar but lacks a lead grade indicator. I saw only one that looked like the Alvin, the Berol Rapid Design which has the lead grade indicator between the grip and the body. So I was pretty much satisfied that I had a representative of each design, but longed for the Rotrings (maybe one day). Then I saw the Ohto Promate PM-703.
A discontinued design of unknown (to me) era it looked very much to me like the Alvin, only in black and rubberized. I figured that it was a similar design on the outside with a different interior mechanism. I had learned form my experience with the K0h-I-Noor and Alvin that looks can be deceiving. Well as things would have it I was able to scrape up enough from my meager profits from my Associated Content publications to be able to purchase a copy of the Ohto. It arrived today, all the way from Japan via Russia! (the vendor who had it is in the Russian Republic). Well I wasted no time comparing it to the Alvin... lo and behold it's the Alvin's twin!
If the Koh-I-Noor is the Alvin's kissin' cousin then the Ohto is it's sibling! The differences in appearances are minor indeed. Aside from the color and the fact that the Ohto has a rubberized barrel the major differences in appearances are the fact that the knurling on the Avlin is courser than that on the Ohto and the way that the grips taper to the the lead sleeve. If one did not know that the two were of different makes one could hardly be faulted for thinking that one was just a slightly different model of the other. Both are really great looking pencils (except for the yellow color of the Alvin's barrel) and the stats on them both are almost exactly the same! The differences are minor and not worth mentioning and could be attributed to differences in tolerances if in fact they were of the same manufacturer. They even weight the same! But that's not where the family resemblance stops! Not by a long shot!

Someone else may feel slighted at having bought 2 almost identical pencils, but not me, and not any true pencilholic. It's the slight differences amongst all the sameness between the "twins" that make having them so interesting. As a collector/user and true pencilholic I think it's great finding two pencils from two different Japanese manufacturers that are so much alike! It makes me wonder, did one company clone the other's design (as if that's never happened)? Are the 2 companies owned by the same parent company? Did one designer sell the same design to both companies? Just what is the story behind these 2 pencils? I guess as time allows I'll just have to search the Net and find some answers.
And BTW, did I fail to mention that I really like the design of the "twins"? Well, I do... ;-)

Thank you for this post! I (apparently) have the Ohto Promate PM-705, although I didn't know it until reading your post. The writing had worn completely away on my pencil, so I've been looking all over to find another, without luck until now.
For some history, I bought the pencil while in engineering school in 1996. It lasted me for every page of notes, every homework assignment, and every test for the remaining 3 years of school. Even after bending the sleeve a couple times and wearing the diamond grip down to semi-smoothness, it still works like a champ. I pulled it out again for my MS in engineering, and it got me through another 2 years of notes and tests. I still call it my lucky pencil.
Now...I can finally get another one, although it looks like I'll have to do without the rubberized barrel. I can't thank you enough for figuring out the Alvin and Ohto are basically the same pencil.

Andrew,
If you follow the above url you'll find Andrey's Pencils on eBay. He currently has the Promate in 0.3 mm, 0.7 mm and 0.9 mm. If you want a 0.5 mm email him and ask if he'll be getting in any.

If you happen to run a across a Berol RapiDesign, you should buy it. They are a nice pencil and fairly uncommon.
Personally I prefer the DraftMatic over the Rapidomatic, though they are both good pencils. The Alvin's lead is cushioned by a spring -- you can push down on it without breaking the lead. The Rapidomatic doesn't hve that feature (at least mine don't).
Nate,
Thanks for the 411 on the Berol. I'll have to be on the look out for it.
