Why are HOCK blades shaped like that?
When we first started making small batches of blades for the Krenov shop, we just rounded the top corners off so they wouldn’t be sharp. As demand grew, we just kept on doing it the same way and it became a trademark. If you want the top to be trapezoidal or round or whatever, use the grinder -- we won't mind a bit. (Just don’t let it get too hot below the slot.)
