KNIFE MAKER
I had a leftover piece of 1084 & 15n20 twist damascus that I made a small hidden tang blade out of. Last night I clamped it to my bench to sand and the clamp slipped off the tang and the blade hit the concrete. When I picked it up, I noticed the crack in it.
Does it seem odd that this caused a crack, especially where it cracked. The blade was forged, triple normalized at 1600, 1550 and 1475. Then it was sanded to 220, heated to 1500 and quenched in quench oil I got from trugrit. No soak times on any of the heating. It was tempered twice at 375 for 2 hours each time.
I use this to check temperatures in both the forge and the toaster oven.
