Found at estate sale. This knife was stored with cosmoline and stuck in sheath. Doesn't look like it was ever sharpened. Appears to be hand scrimshawed handle. (Nuguruck) Guessing knife is 50's-60's vintage. 11.5" total length. Blade is 6 5/8". sheath is a little dry but no damage. Trying to get some history and idea of value.
