More than most humans want to know about tool steels

Came across this today. All I wanted to know was if Neatro lathe bits were any good, but I got trapped.
Beware.

That is an excellent reference. bfk! Copied to my archives, still reading it. Should be required reading material for everyone using old machines, buying old lots of tools, trying to get better performance from their machines, and knowing what to buy and what to avoid. It is a long read, but WELL worth it! Thanks for posting it!
