Oil hardening vs water hardening for tool steel - which is actually better?
I was reading that old copy of "Practical Blacksmithing" by Richardson I picked up at a flea market in Topeka last summer, and it claims water hardening gives you a tougher edge on chisels, but I've been doing oil hardening for years and it's fine. The book says water quenching creates more stress fractures, but my grandpa swore by it for decades. I'm curious what everyone else here uses for things like drifts or hot cuts, and if you've actually seen a difference in durability.
