I'm always interested in ways to get more out of steel. I am having a hard time understanding what you are hoping to accomplish. What are the milled quench blocks doing that regular quench blocks don't do? This isn't sarcasm. Maybe I'm a bit dence and missed something. What steels are you using and what are you hoping to study? If you want to test blades I might be able to send you a couple.I imagine that you will need some sort standard blade if you want a controlled teat.
