Thanked: 170And, as you well know, that is why we have to anneal and normalize before we heat treat. Any time we heat into the 2 to 300 degrees above critical, we get grain growth. I made a knife from a file that I did not follow the steps with several years ago, and when I accidentally dropped it on my concrete floor after heat treating, it shattered. Lesson learned. This thread is good information for folks that are new to forging blades - I know it is not new to you, Bruno. Happy forging.
