>>2253897That's a knock of Pentel P20x, like
>>2253917 said, they come in every common size, including 0.3 which is only sold in Japan (but you can get from
jetpens.com). They've been making them forever and they last forever. They're light enough that you can drop them on the tip and it won't bend. Very dependable and the standard other drafting pencils are measured by.
If you want a family heirloom type pencil, the Rotring 600 is amazing (I have 3), but it's weighty enough that if you drop it on the tip you'll break it. A new pencil is $25, but a new tip is half that.
I collect drafting pencils and have a few hundred dollars worth of good ones. They only thing I would avoid are things like
>>2254362 and
>>2254484. They're great for writing, but for drawing you don't want the tip to move on you. Everything else is personal preference. At the end of the day if it holds lead and you like it, that's all that matters.
Try out some different leads (2H, HB, and 2B is a good mix) too.
"Dave's Mechanical Pencils" (Google that) has some nice reviews. I thought he killed his blog until I checked again just now. That guy has an insane collection.
>>2253945These are also amazing and can take the widest variety of leads. If you get one, make sure you get the Rotary Sharpener.
>>2254467The hole in the metal cap where an eraser would normally be is a sharpener, but it's much cleaner and faster to use a rotary one.
