Some time back I bought three cheap (very) ones on e-Bay for $9.95+shipping. . . one lost the "stone" and the blade came loose. I still have two others, and they hold an edge surprisingly well. Of course the blade is in "backward", and I am thinking of getting a bone to use as a handle and remounting the broken one. If I do, I'll post pictures. I do have a really nice one, but I only wear that for dress occasions, if I lose one of these, no big problem.
