Vent: been quenching my 1084 in warm water for 6 months and a guy at the Rockford meet tipped me off
I was quenching 1084 blades in a bucket of warm tap water because someone on a video said it was fine for simple steel. At the Rockford meet two weeks ago a guy watched me dunk a blade and asked why I wasn't using fast oil, then tapped the edge with a file and it bit in way too easy. Turns out a bunch of my knives from this batch are sitting around 50 to 52 HRC instead of where I wanted them, and I've been handing them to friends. Now I've got a pile of 8 blades I need to redo and I'm second guessing everything I thought I knew about heat treat. What oil are you all running for 1084 and how are you checking hardness without a tester?
