I got this KaBar folder thrown into an eBay auction I won. I put it in a junk drawer and forgot about it for a few years. Cleaning out some things This morning, I ran across it and some SAK blades from previous mods. Took only about an hour and I had a new favorite pocket knife. Real good snap from both blades. I could have, but chose not to do any grinding on the new blades. Just put them in.
