I have a slight problem with the 'rabid' Kuru Toga followers - most of them seem to be either FP aficionado with little pencil experience and a whole lot of flex nib bias, or just people first getting into pencils. Not a knock on you though, it's just that the reviews and popularity of these on JetPens and the community at large seem to eclipse any chance of other pencils getting a chance to shine (like the OLEeNu pencils I linked above that seem to be just as ingenious as the Kuru Toga in that it solves a problem a lot of us pencil nuts have been aware of).
There's also the fact that the pencil is not for many, as some would put it - the pencil perfected.
The biggest takeaway is that the tip has a ton of give, by design, in order for the mechanism to work. Even for those not requiring drafting precision, it really takes away from the overall feel.
Not to mention, the mechanism itself. Yes, it works, it works rather nicely - but only when you have it at a particular angle. For those of us that hold their instruments very close to 90 degrees out of habit, the sharpening doesn't really help a lot. Plus, with those of us that hold the pencil at a very shallow angle (I'd imagine sketchers like me primarily though an auto-sharpening mechanism isn't exactly what sketchers look for in the first place - probably a bunch of other writers though) the mechanism also falls short. With cursive/pencil-draggy writers, it's ever so worse because the mechanism just isn't beign activiated at all.
Now I like the Kuru Toga (I mean the name itself wins a ton of cookie points by itself), despite all of that. The regular 0.7mm version is one of my everyday carries. And heck, I've got them all at this point, another of the Alpha Gel version should be coming in soon, and I'm looking at the rubber-gripped version in my cart as we speak.
But for pencil/pen users, 50% of the whole experience is in the feel of the writing experience. And I have to say that the Kuru-Toga will never have a solid enough experience for me to dub it as the ultimate pencil - something that people seem to flat out enjoy doing at this point.
And this is less of a critcism, and more of a wishlist thing - the Roulette and the High Grade could do with a little more weight up top. That's primarily personal preference though and I won't use it to detract anything regarding the pencil. Hopefully one day they'll go with a thicker ABS plastic or some sort of metal on a higher-end variant of the Kuru. Uni seems adverse to that though - the Uni Shift does the same thing with the body and has that weight problem, which is why I probably enjoy the Ohto 1000P a bit more as a twist-to-retract mechanism MP.
