Alan I agree and I usually take files to the grinder and smooth them out. but this one was ordered with the teeth left in. to try to keep it from breaking I annealed twice before HT. The HT method I used was Godard's goop quench and clay for a differential HT. tempered to light straw 425 3cycles. tested the point by dropping in to concrete (always scares me), then batoned kineding. final test batoned a 2x4. had no bending, warping, chiping, and remained hair poping sharp. I am amazed at how well it held up. I might make a few more and test to destruction.
