Reddit mentions of Uni Mechanical Pencil Kurutoga Pipe Slide Model 0.5mm, Black Body (M54521P.24)

Nice collection! I have a few more items for you to consider adding, should you be so inclined:

• Uni Kuru Toga Pipe Slide: Plastic variant of the same line but with a retractable tip. Although I prefer the feel of the Roulette (which you already have in silver), I carry the Pipe Slide in my shirt pocket every day because it won't poke holes like the Roulette does. For those unfamiliar with the Kuru Toga line of mechanical pencils, they automatically rotate the lead every time you press it to the paper, avoiding flat spots and keeping it sharp on all sides. Note that this occurs each time you press down, not as you keep pressing. Thus, drawing a line rotates one notch (because you only set the tip to paper once), whereas writing letters, dots, etc. rotates multiple notches as you continue to repeatedly press the tip to the paper for each character.
  
• General's mechanical eraser: finer tip than most mechanical erasers, and nice pen-style grip. Refills are also available but I've found they're often cheaper locally. (Amazon sells 3-pack refills for ~$4 but my local college art store sells them for half that.)
  
• Tombow Mono mechanical erasers: Extremely fine erasers for detail, more than even General's, for uses such as erasing small lines while drawing. You can order sets of both shapes (round and rectangular) or just one, and they're available in silver or black.

I've heard if you want to write with the pencil more than you're drawing with it, you want to go with the rotring 500. I believe it's made with more plastic and less brass so it's lighter, and you can write longer.

Might also want to look into a Kuru Toga, they rotate the led so you dont have to readjust the pencil and he led stays sharp. I would recommend the Roulette or the Pipe Slide. As long as you don't lose them they'll last you years.

These are already released: http://www.amazon.com/Uni-Mechanical-Pencil-Kurutoga-M54521P-24/dp/B017BDDZ7I

I really hope that Pentel (my favorite brand) or even staedtler makes something new this year. That would be awesome. I feel like no new good pencils come out (IMO the recent Graphgear 800 and Rotring 800+ were bad)

The pipeslide is also a wonderful model by the looks of it. I've never used one before, but I do have a Pentel Orenz, which also has the sliding pipe mechanism.


As for how the kurutoga, it's a light pencil if you're into that. The paint on the models with they shiny overcoat WILL wear down over time, which is what happened to mine. But asides from that, they're pretty durable. They're great for the price. If interested, there's a bunch of designs you could choose from. (try searching up the pikachu kurutoga pencil lol)

I'm exclusively a 0.5mm lead user.

My preference is a 2B or a 3B for smoothness, and I use Pentel Ain Stein lead. (Got a multi pack from 2B-4B for $12) It tends to write slightly darker than a standard lead, however, it does get used up much faster. This for me is not an issue since the difference at least in my hands is so much smoother.

There are many notebooks to choose from, maybe check out /r/notebooks but be warned your wallet might hate you. I like the Semi B5 size since it is without margins and if you write small it approximates the similar writing area for my personal use since I never used the margins in the 5 star notebook types. The lines in the maruman are very light and easy on the eyes. The paper is very heavyweight and thick. I typically find it hard to see through the pages so you can write on both sides without seeing lines pass through. The covers are a heavy duty plastic material and great for long term use.

I got these notebooks for archival purposes. I use them to write down engineering formulas and notes on designs -- things that I need to constantly reference and have handy. I paid about $8 each notebook with tax and shipping. Highly recommend them!

Here are the particular items I got so you can take a look:

https://www.amazon.com/gp/product/B00OPQA7SK - Eraser (Don't buy the multi pack the erasers suck, but the holder is awesome. I took a Pentel Hi-Polymer eraser, and cut it up with a razor blade to shove on the sticks this thing comes with. Best eraser you can use! I also have the Pentel clic but it's not as good as the blocks since it's a harder polymer so it smears and doesn't erase perfectly.)

Also, shop around. Prices vary greatly for these items. Amazon may not be the cheapest, and sometimes Jetpens can be a huge ripoff so shop around before you buy!
