Bob Ouellette 3 Posted August 9 Hi all, I forged my first chisel ground blade, a chef's knife, is there any noticable difference in the heat treatment? I'm wondering about the possibility of warping in one direction or another due to the asymmetrical geometry. The knife in question, in case anyone wants a peak.

Joël Mercier 338 Posted August 9 The only chisel ground kitchen knife I did was in W2 and clayed for a hamon and it did not warp. Even so, a softer spine makes straightening a breeze. But an asymmetrical grind indeed does increase chances of warpage. Quote Share this post Link to post Share on other sites

Also @Bob Ouellette traditionally, this blade type has a slight hollow on the other side. Without it, sharpening is a bit awkward. 1 Quote Share this post Link to post Share on other sites
Bob Ouellette 3 Posted August 10 Thanks @Joël Mercier. I have to go to work today to pick up some paperwork, so I'm going to use our 20" disk sander to add that slight hollow. Quote Share this post Link to post Share on other sites
