I can't date it exactly but D2 was first stainless and a patent for it was applied for in 1904. This Sheffield is definitely carbon steel and has pitting on the blade.. I had it reworked completely since the blade was unused. Cocobolo for the scales and new pins are Norway iron....the crimped brass bolsters and the liners under them are original and I couldn't say what the original wood was but cocobolo suits it well. 4" closed with a 3" sharp blade. You need to see the video on YouTube, 3fingermac...then hurry back before someone beats you to it. I used this knife as a spec guide for the Kroo Lambsfoot, 2 in Kudu bone available now. It's a difficult pattern to make but you get one great knife. Knife only..ships next day free USPS Priority.
