After being introduced to a better way to sharpen knives from my
old Scoutmaster who is now my son's Scoutmaster, I looked around
to find a small stone I could take in the field for touch ups.
I have one from the hardware store, a diamond hone that I pulled
the plastic back off and now have one that fits in an Altoids or
wallet and weighs just .4 ounces. Does a reasonable job of re-
sharpening. What do others use?
