This tanto is in the process of being made by a student of mine who is a Marine veteran, Emilio Fernandez @fernandezindustrial. It is ground from a 1951 Ford pickup leaf spring, with stamped markings still visible on the tang. The blade is 5 1/2", the overall length is 10 1/4", and the blade is 3/16" at the base of the blade, tapering distally to the tip. It is ready to be heat treated. This is available for sale. It will be getting an epoxy-hardened cord wrap and a Kydex sheath. Price is $150 for the knife and $40 for the sheath. If interested, send an e-mail to email@example.com with "Tanto" in the subject line.
