Has anyone tested DC53 tool steel as a blade material? I found a couple knives and one that was made and tested by "Moonless" a Thai knifemaker but all the reviews are in Thai so I dont understand it. The pictures look good that I saw "chopping concrete bricks and ice picking metal" but I was looking for more info if any is out there. Im in the middle of grinding some now and would like any info I can get before I start heat treatment. thanx
