Fantastic mechanical pencil. Not heavy and well balanced. Feels cool to the touch. Writes beautifully and very sharp.

Exactly as described, arrived promptly and in perfect condition

The mechanical pencil feels luxurious and good quality. Great grip. However, the bottom half is plastic, and the rotating mechanism is slower than expected.

One of those, 'Wow, why didn't we have this before?' moments. I was a little bit suspicious of paying this much for a pencil. You can get them free or seriously cheap, so why spend £8 on one? Well, if you are partial to a sudoku or crossword and get frustrated with pencils breaking or even having to find the rusted wooden pencil sharpener at the bottom of the drawer, this is the answer. It consistently has the same sharpness, giving the benefits of writing with a pen without permanence.If, like me, you struggle to decipher the Japanese on the back of the packet, it works by rotating the lead slightly every time you lift and release pressure on it. [You can tell it's working by looking at the little logo go around and around]. The sharpening works particularly well with many small strokes (for example, if you are writing Japanese characters) or when doing numbers and crosswords. However, it's going to be less good if you are writing in cursive or anything joined up, but even then, crossing letters and dotting i's seem to do the task.Even the rubber is nice. My only slight niggle is that it's heavier than other pencils, but not overly so, and if you have used a metal mechanical pencil before, it will feel normal.It won't replace the Blackwing for everything, but it's a great purchase either way.

I have always liked a mechanical pencil - the perfectionist in me likes to know that I can erase any mistakes, and it takes the anxiety out of writing on my new calendar or diary (yes I know that’s a bit sad). This one is actually the best that I’ve had, and I do like the fact that there are no ‘flat spots’ on the lead. It’s not the more comfortable for me, but I can forgive it that for the writing experience. Would recommend.

These pencils are excellent. The clutch mechanism works great and the grip is good. Very light, though still feel good in the hand. I've dropped mine a few times and it hold up well.I bought another, one for the backpack and one to keep at the desk.

I'm an artist who, amongst other things, creates linoprints, wood engravings, etchings, etc. I've always had problems, when editioning a print run (i.e., writing the print number - 3/10 for example, the title and signing it), in finding a pencil that has a small enough and sharp enough point as I often have to write very small text. I read about this pencil and thought I'd give it a go, and it's EXACTLY what I needed! Fab!

I just had to give this 5 starts as I need a pencil for studying A level maths and this is the best pencil I've ever owned.Previously I've tried disposal mechanical pencils and a Staedtler Mars micro 5.0mmThe auto rotate (stay sharpe feature) that many say doesn't work, appears not to do anything I definitely don't notice it doing anything and my lead would still blunten and I myself quested if it really worked or just had some kind of placebo effect. However upon returning to my Staedtler for a day (couldn't find my Kuru Toga) I soon noticed the Staedtler blunted much quicker and easier. I therefore conclude the the rotation stay sharpe feature does work pretty well and although not perfect I really couldn't do without this feature anymore, I actually love this feature.The quality of this pencil is very good though unfortunately only the bottom half is aluminium the rest is aluminium look plastic although this maybe slightly cheapens the look and feel it is still a very solid and attractive pencil.I actually felt quite posh using this in maths class, default the best pencil and smatest looking pencil in my class.I really don't know how easy it would be to source replacement rubbers for the top but I don't really care as I like to use my large quality rubber which I already own.Personally I prefer the Staedtler leads as they Seth to write smoother so I buy replace 5.0mm lead from them. Any 5mm lead should fit fine.If like to point out that the Staedtler I've been comparing to is an excellent quality pencil and perhaps better value (depending on current prices) but I simply prefer the Kuru Toga.I'm actually after a 3mm pencil now and won't buy any other brand, once you've tried a Kuru Toga there's no going back.On that note I'll end this review with a few pictures, hope you have found it useful
