I haven't had time to repeat it yet. I'm trying to figure out what I need to change for my next test.

Edit: my canola oil was only around 80° at time of quench. Could that be the culprit?

Steel is 80CRV2. I'm messing with my heat treat and have access to a Rockwell tester at work. Piece number 1 is a chunk of raw stock that I cut off, piece number 2 is a chunk that I normalised (10 minute soak @ 1600° ctb, 10 minute soak @ 1480° ctb, 10 minute soak @ 1250° ctb.) Piece number 3 was quenched in warm canola oil after normalizing then a 5 minute soak @ 1500°, piece number 4 was tempered twice after normalizing and quenching, first for one hour @ 375° second for one hour @ 400°. Piece #4 is right where I would expect it to be, around 59-60 HRC but piece #3 has me worried. I was expecting it to check around 64-65 HRC but it is barely checking harder then the piece that I tempered. Did I screw up somewhere? What would explain my quenched piece being the same hardness as my tempered piece?
Just completed my first knife!

This build has been a month long and 50 hours of work in the making. When I first started I had no idea if I would enjoy it, or if I would even be able to make a useable knife. Now that it's done I'm struggling to describe the joy and satisfaction that I felt holding the finished product and knowing that it had been made by my own two hands. I would like to extend a huge thank you to everyone on this forum. I havent posted very much, but I have been reading for months and I wouldnt have been able to do this without your insight and knowledge.
