Bob Ouellette 5 Posted August 9, 2019 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 493 Posted August 9, 2019 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. 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 Share this post Link to post Share on other sites
Bob Ouellette 5 Posted August 10, 2019 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. Share this post Link to post Share on other sites
