The double speed "Kurtoga Engine" and metal parts keep the core sharp at double speed, and the line width becomes even faster and narrower.

Review: Great pencil - I’ve been using the Uni Kuru Toga Advance Upgrade Model 0.5mm mechanical pencil for a bit now, and it’s easily one of the best pencils I’ve owned. The standout feature is the rotating lead mechanism—it keeps the tip consistently sharp as you write, which makes a noticeable difference in how clean and precise your lines look. It’s especially great for neat handwriting and detailed work. The build quality also feels like a step up from standard mechanical pencils. The metal grip adds a nice bit of weight and balance without being uncomfortable, and it gives you a more controlled, premium feel in hand. The grip itself has just enough texture to keep it from slipping, even during longer writing sessions. Another thing I really appreciate is how well it prevents lead breakage. The tip design and internal mechanism work together to make writing feel smooth and reliable, even if you tend to press a little harder. Overall, this pencil strikes a great balance between smart engineering and everyday usability. Whether you’re taking notes, sketching, or just want a consistently sharp writing experience, this is a solid upgrade from your typical mechanical pencil.
Review: Good quality, I recommend. - These mechanical pencils are awesome. Every time you lift the pencil up after writing it rotates the lead a little bit so, in theory, you will always have a sharp pencil. Writing in cursive, though, it really doesn’t work any better than a pencil. I find myself rotating it to the sharper side. It was designed for lifting the pencil with every jot and tittle. Other than cursive, it writes great and it’s a good price for a quality mechanical pencil. I tend to go for the 0.5 because it writes sharper. The size is compatible to other mechanical pencils. It does come with a few extra erasers. It’s one of the more comfortable ones out there and I like this style better.

## Questions & Answers

**Q: Can I use any other 0.5mm lead?**
A: Yes, you should be able to use any 0.5mm lead.  I've already reloaded my pencil with spare lead I bought.

**Q: What is the difference between kurutoga advance upgrade model and kurutoga standard model?**
A: Standard Kuru Toga pencils rotate the lead once every 40 strokes, while the Kuru Toga Advance rotates the lead once every 20 strokes. The Advance's mechanism is made with metal parts for smoother, more reliable performance.

**Q: Can you see the rotation through the grip holes?**
A: No, but if you remove the tip and the external bezel, you can see the whole mechanism in a transparent plastic tube (It is really nice). Then there you can note the mechanism moving while you use it.

**Q: what kind of erasers do I need to use to refill the pencil when low?**
A: Advance models use size "S" refills

### ⭐⭐⭐⭐⭐ Kurutoga Advance Upgrade - The W-speed engine DOES make a difference!
*by K***R on August 25, 2023*

Just received my Kuru Toga Advance Upgrade 0.5 mm mechanical pencil. TL;DR = What an Excellent Pencil! And the W-speed engine makes a big difference. Prior to owning this, my "go to" pencils were: (1) the Pentel GraphGear 1000 0.5mm (limited edition black), (2) the Pentel GraphGear 1000 0.7 mm, and (3) a standard Uni Kuru Toga 0.7mm (black barrel). My standard Uni Kuru Toga *works*, but is a distant 3rd place because of two issues. First, the lead sleeve doesn't retract, leaving it to poke holes in my pockets, digging into me if I move wrongly, and/or accidentally getting broken off on a hard surface. Second, while the Kuru Toga engine *works* (and is awesome), it was designed for writing Kanji, Hiragana, and Katakana. Those use MUCH shorter strokes than the Western (Latin) alphabet, so the lead is turned more gradually than I would like. Enter the Kuru Toga Advance Upgrade. PROS It has the new W-speed engine. (I assume the "W" stands for "Western Scripts.") This rotates the lead roughly TWICE as fast as the standard Kuru Toga engine so that it stays sharper when writing in English. I can confirm this works, and works well. The lead sleeve is retractable. I could wish that it had the niftier mechanism found in the Pentel GraphGear 1000, but it certainly works well enough that I can carry it in a pocket without breaking it or having it stab me. The lead sleeve "rides" up with the lead as you write. This little trick reduces the number of times you have to click to feed the lead, and is a welcome feature. (If you want a true auto-feeding pencil, Uni makes the Kuru Toga "Dive" which advances the lead every time you lift it from the page. It even has a feed speed adjustment!) The color is vivid. Mine is a deep vibrant red and the metal and plastic parts all match without color variation. It is a beautiful, professional looking writing instrument. CONS The Kuru Toga Advance Upgrade is both shorter and lighter than my GraphGear 1000. This may be a "PRO" to you if you prefer a less-weighty pencil, but I would spend an extra few dollars in a heartbeat if they made a heavier, all-metal version. The sleeve requires pressing on a hard surface to make it retract. This is just a MINOR nit! But I prefer how the GraphGear auto-retracts when I squeeze the top of the pocket clip. Coolness Factor? My standard Kuru Toga has the window that shows the engine. When I pull this out in front of any fellow pen/pencil afficionado, they ALWAYS immediately ask about it! Of course, my "Advance Upgrade" pencil looks a WHOLE lot more professional... but I'd certainly buy a version that had the clear window around the engine. Better yet? Sell a version that has swappable lower barrels -- you could then "dress it up" for professional meetings, or "geek it up" when you want the coolness factor. (Are you listening, Uni?) .
