UPDATE On this broken blade!!! First off let me say. As soon as Damasteel saw this a rep from the company contacted me... which is awesome. It’s gonna be on its way to their engineers to get looked at. You guys speculated a lot on what went wrong. Which is great. But let me say this. I have worked with a lot of steel from at of different manufacturers. Damasteel make the cleanest, purest steel I have worked with. I’m not just saying the cleanest Damascus (although they win that category by a huge landslide). It’s clean... perfect steel over all. I’ve found flaws and inclusions in every brand and maker. I’ve never seen one in a damasteel product. From what I can see under magnification. There is NOT one here. I’m also meticulous about heat treating. It’s a science, and I treat it as such. I also check the Rockwell hardness at each step in heat treat. After hardening, after Cryo and, and after temper. It’s a check and balances system to confirm that everything went well. This blade was spot on at every step. What I think happened. I think it cracked after Cryo when I Rockwell tested, before I tempered it. It was at its hardest and most brittle stage right then. I suspect I tested to close the edge, which had some vertical 6O grit scratches, and it just separated a bit because I applied a heavy load of single point pressure on a very brittle (at that stage in heat treatment) surface. While I’ve never had it happen before... the engineers at Damasteel should be able to tell. Please understand what I’m saying. I DO NOT blame damasteel for this. I shouldn’t have posted that it was damasteel. But that cats outta the bag. I’m sorry @damasteelab I was simply frustrated breaking a super awesome blade a few days before a show. So let me again say. Damasteel is the fantastic material, and I intend to continue to work with it, it’s pretty much my exclusive Stainless Damascus product. Because no one else has come close to makeing such a perfect material with excellent knife properties.
