Hmmm. Last one I did -- and sold (stupidly) -- I just folded up the 
chain to about 4 or so inches length, wired it with iron mechanic's 
wire and welded it in the forge. I took many heats, used lots of 20 
Mule Team, and went relatively slowly. Closed it up in the thin 
dimension first and worked it into about a 1/4 X 6 billet through 2-3 
folds, rough forged a knife shape and then ground it and etched. Made a 
really nice small skinner.

Looked like a randomized mosaic pattern because the teeth made brighter 
lines and spots in the metal.

I don't know exactly what steels are in those things, but normalizing, 
then a water quench and 400 degree draw turned out pretty good.

The best thing about the thing was asking people what they thought it 
had been in its previous life. :)
