I have a couple of old messed up straight razors that I want to try forge or grind into some small knives. These are typically referred to as "Sheffield" steel from the England.

I just wonder if it needs to be heat treated any differently than a typical high carbon steel used for knives today, anyone have a clue?

Thanks

Just make something!

If you haven't ruined the original heat treat I'd just grind them hard.  If they have been annealed then heat to non magnetic and quench, probably a fast oil or brine.  Not sure of the carbon content of those old Sheffield blades.

I'm thinking of trying to put a curve in one for a carving knife. So you think an oil quench then temper at 400 degrees should be good?

That should work, might even do a 375 temper for the first round to see how it does.  If it's still too hard then you can always bump the tempering temp and go another round.
