While at the county farm auction back in the 70's, an older gentleman called out to me, "let's drop knives".
I said that my knife was junk but, he insisted. He dropped in my hand a case xx whittler redbone three blade. I told him that I couldn't accept but he again insisted.
That is the sharpest knife I ever had. I once cut a fly in half in midair with witnesses. The edge would dull just from
the moisture in the air, I guess, but a few strokes on a hard Arkansas would bring it back to scalpel sharp.
