D2 tool steel blank
I have a knife blank made from D2 tool steel. I've heard this type of steel is very difficult to heat treat. Is this true? Are there any tricks to doing it?
"Throughout history, it has been the inaction of those who could have acted; the indifference of those who should have known better; the silence of the voice of justice when it mattered most; that has made it possible for evil to triumph."
