The two Uni-Ball Kuru Toga pencils, in 0.5 and 0.7 mm, have diamond-impregnated lead that’s supposed to be much more break-resistant than usual. I fear that they’ll land point-downward and wreck the rotating sleeve surrounding the lead, so I’ve managed zero drops so far. Even I hesitated at the 0.3 mm version.

They had me at “0.20 mm”

    The Uniball kuru toga pencils are to me like the one ring is to Gollum. “We wants it, we needs it. Must have the precious. “

      I know that feeling: Uniball Micro 0.5 mm blue pens. Bought ’em by the pack, until they morphed into something slightly different and better.
