Thanks guys, I'm starting to like knives more than bows.... almost.
Kevin, this is how I did this one-
Normalized, brought it up past critical three times only letting it cool to about 500 between each one and then it cool to room temp.
HT'd, I brought it up to critical and quenched three times and then tempered at 400 for two - two hour cycles. I don't know the RC but all of my files skate on it. It took and so far is keeping a nice edge
