I just finished these 2 paring knives for a client, shipping out tomorrow. The handles are Hawaiian Koa, one of the most beautiful wood species out there. The steel is 15n20 (such an underrated carbon steel) at 63HRC, sourced from the New Jersey Steel Baron. This particular batch of 15n20 was slated for band saw production, so it came hardened in the mid 40s (if memory serves). I like to know the exact condition my steel is in, so I didn't take any chances by simply hardening and tempering it as received. The 15n20 went through a normalizing cycle, 3 thermal cycles, a pre-quench, and final hardening/tempering. I also like to take paring knives down to a "zero" edge, and then knock them back just enough to establish a flat that will just reflect light. This makes sharpening a cinch, and superb performance! Edge is 25° inclusive, Shapton Pro 1000. Thanks for looking!
