Hey guys. Been a lurker and infrequent poster for a few years now. Starting to get serious about knifemaking (finally), and I had a question about warped blades. I'm not a fulltimer, and I'm only producing a couple of blades a week at this point, so I have a little more time to dedicate to each blade. I'm using solely 5160 at this point. My question is this. If after quenching I have a warped blade, rather than trying to straighten immediately post-quench (around 500 deg F), why not just renormalize, then straighten under heat, then reanneal, starting the entire ht process over again? Sure, it's time consuming, but from a metalurgical and end product standpoint, is there anything functionally wrong with that approach?
So just to be clear, what I'm suggesting for input is the following:
Step 1: Renormalize
Step 2: Straighten in vise while still hot (is 500 deg F sufficient?)
Step 3: Start entire ht process over
Just to be clear, I tend to use a version of Ed Caffrey's ht recipe, if that helps.
Thanks in advance, guys. Any assistance would be much appreciated.
