The Kuru Toga eliminates this problem with the use of an ingenious lead rotation mechanism that continually rotates the pencil lead as you write. A spring-loaded clutch twists the lead incrementally every time you lift the pencil from the paper. This allows a uniform wearing of the lead to create a conical tip shape that provides a fine, consistent line. I thought I’d share this because, from my experience, there does seem to be a quality control issue with Kuru Toga pencil manufacture [at least as far as the plastic ones are concerned] because I’ve experienced ones that require what I’d call too much pressure to work.

Kiki's Delivery Service - Everyday Items, My Neighbor Totoro - Stationery, Spirited Away - No-Face and All the Deities The Kuru Toga is a mechanical pencil from uni / Mitsubishi pencil. In Japan it has been available for more than a year. The plastic version is now officially distributed in the UK and other countries, while the successor, the new Kuru Toga pencil, is already available in Japan.Sadly this pencil just isn’t for everyone. The construction seems good, though the material choices and weight aren’t my particular favorites (the regular Kuru Toga is almost entirely plastic, quite light, and neutrally weighted). and the inability to fill in as many spare leads as in some other mechanical pencils (maximum 4 – 6 leads, depending on length and whether you try hard to squeeze them in)

As many of you have post about problems, I’m not sure is it because of writing in different language. For example, English language can be written one word without lifting the pencil, while Japanese have to lift the pencil several times for one word. Therefore Japanese language may be rotated 10 times faster than English (Just my guessing). The turning mechanism works great for writing where there are plenty of strokes. When it comes to drawing, whether or not the pencil will turn will depend on how long your lines are. So if you draw a long line, that pencil lead will only get turned once. And in that case, it's actually no different from using any typical mechanical pencil. I’ve been looking at the Kuru Toga for a long time, and finally I got one yesterday. I sadly have the same problem as memm, and can confirm that it isn’t merely a defective pencil. My wife and friend have no problem activating the mechanism consistently, and there are two pencils involved with consistent results.

All models except the "Pipe Slide", the "Advance" and the "Advance Metal" (also known as "Advance Metal Punching Grip”), rotate the lead approximately 9 degrees per stroke (40 strokes for a complete revolution). You know how sometimes when you draw for too long, the pencil becomes blunt, sometimes you may rotate the pencil to the sharp side of the lead that gives you a thin line. When you're writing, you'll immediately see and feel the difference. With the Kuru Toga, I can actually feel the difference but can't really see the difference unless I'm really looking out for it. You can spot the Kuru Toga logo inside the grip section or under a window in the barrel. It's printed on the rotation mechanism—which comes in different colors depending on the lead size—so you can watch the logo turn and rest assured that your Kuru Toga is working properly.
