My Puma Tac 1 reincarnated, and not even yet dead, a miracle! Any particular reason why you went flat chisel grind, and, new to me, hollow ground? It is surely a wicked looking thing.

Am glad to see them made of 440c versus more fragile D2 or modern powdered stuff. If he holds the hardness down a notch, they should be tough enough for design, resist abrasion of edge when cutting, and yet easily touched up. And no edge chipping.
