Does the Pentel have a mechanism to rotate the lead? I use a Kuru Toga for that reason, and quite like it, though the machining tolerance could be a bit better, i might try a Pentel for that reason but worry about the lead getting flat on one side as I write.
Only the Kuru Toga have this system. You might want to try the Pentel Orenz which is another approach, with the (retractable) metal sleeve following the lead. Both features seem to me to "get inbetween" me and the pencil while drawing, that control over sharpness is nice, even with 0.5 leads. So ultimately I prefer to go with the Graphgear or the Pentel 120 A3DX (cheap, light, comfortable, reliable, but no retractable tip).
I am kurutoga fan as well. Love the rotating lead and consistent writing due to that. Sadly I keep losing the eraser cap and can't seem to find it online. Any suggestion?
Good question. I used to used cheap ones back in the day and developed a habit of manually rotating as I write. It's become instinct and part of my muscle memory so I don't need this as a feature though I see its value.
