Here's a few more early Montana knives pre BMK stamp.
First knife is a short sword. Almost 14" blade and 20" overall. Gorgeous horn handle, ivory spacer. Mudbone leather.
Second knife, 10" fighter, N/S "S" guard, FWI handle, Mosher leather.
Last knife is a little bit Woodcraft, little bit Alaskan influence. Really great artifact FWI handle.
