4130 for a knife blade huh? Interesting. I didn’t think the popular alloys for firarms could reach adequate hardness for an proper edge. Looking forward to seeing the outcome.
And were considered good knivesFred, can you do Rc testing? I've read RR spikes can hit 50 Rc or so with that super quench stuff. While 50 Rc isn't really "hard" for high end knives, it's amazing how many older carbon steel knives were not much more than that.
This is exactly what I want to learn how to make. Question... what made you try the 4130?
Ah yes I remember now. I bet it’s going to work out ok. They may just end up being really easy to sharpen.Kevin , I bought a coil spring at a yard sale because the deal was to good , spring is 3.5' x 12'' x 1.5'' thick . had a small chunk tested and turned out to be 4130.
