FS: Pentel PS1045 - SOLD

I have a Pentel PS1045 for sale. It’s a beautiful piece but does have a small crack that these models suffered from. The crack is super small but I used my macro lens to capture it for you to see.

$50 + shipping


nice. too bad I am broke now. lol
Looks like according to @nimrodd Pentel ID Book, that 1000 Yen tag means its an early model!

I do not have the exact date that the PS1045 began distribution, so I just list the PS1042 date to start. The last catalogs I have with them in it are the US and Japan 1980 catlogs.

I also do not have a date for the price change. Looking at the model number, I suspect that thte PS1042 was also released at ¥1000 as well, but I have never seen mention of that.


Is it a stress crack from manufacturing that wasn’t detected, or a materials fault that eventually happens simply by aging?

It’s a common stress point revealed by aging/use.

The lacquer-coated Ohto Piston Sharp SP-20 (black) suffers from a similar issue, as do certain Tombow Exta models (the lacquered ones, not the woodgrain ones).



Luckily this one can barely be seen with the naked eye.

Good to know about the SP-20. I had thought about making a complete OHTO Piston series collection, but with all of the issues on the SP-5 clear tips suffering cracks (even when looking perfect, just suddenly cracking on you from very light use) I dropped the idea. Then I thought maybe going from SP-10 on up. But if the SP-20 has this kind of fault… meh.

Same piece being sold for a weebit more. No price sticker and I bet if you looked closely it has at least one hairline crack.


Well if nobody here takes a shot at it, I’ll take the pencil. Hit me up in DMs on how to send the moolah.




It’s a nice price. I was quite tempted. You may be able to stabilize the crack with just a touch of solder. Or even some JB Weld.
