I cannot make out the manufacturer of this knife, only the Sheffield mark is readable. This is one of those rare knives you see now and again with the cyphers stamped on the blade. I do not know what they mean, nor does anyone else I have asked. The knife is 12 1/4" total length with a 7 1/4" blade. The blade is stained and lightly pitted. The dinnerware handle is copper colored. Comes with a leather sheath with german silver ends. A very rare and hard to find Bowie.
