I decided to trade my Custom Leethal Cutlery Bushcrafter in San Mai steel. I have attached a picture of the note that Mason sent me with this knife. It has not been used at all. Has red liners. He explains the clouding on the blade in the note as part of the heat treat process. It is a user grade. Love this knife and he did a fantastic job on the sheath. Firesteel is included. Please e-mail with any questions. tjroberts27 at gmail dot com. U.S. only please. Thanks for looking. Interests include Bussekin, Chris Reeves Knives, Emersons, Southern Grind and other Customs... Never know. Make me an offer.
