I got this recently and have been busy polishing the Ulili-key back into shape. Considering I have virtually
no experience in the area, the fact it can cut paper again speaks volumes of the sharpener's quality... In any case, I tried shoving it into the "tool" pocket on a sheath along with a SAK or Blast Match, but it made scary noises and became covered with black residue. Each item fits comfortably on its own.
Now, I don't mind taking a few layers off the plastic. What concerns me, is whether or not doing so will wear out the sharpener itself. Should I do it?
