This knife was just finished this past weekend, and I'm calling it the "CUB". Chef's Utility Blade. Made from 52100 and gorgeous quilted maple and purple heart. New heat treatment protocol I am using on 52100 these days: Following normalizing and then thermal cycling 3x, I have added a DET annealing process (divorced eutectoid transformation) which re-spheriodizes the carbides after the normalizing and cycling. Raised the austenitizing temp from 1475°F to 1525°F (15 minute soak). Quenched in Parks 50 and then sub zero quench with dry ice slurry down to -100°F. 3 2 hour tempers @ 300F for a final hardness of ~64-65HRC. Blade was hand rubbed to a true 800 grit, and the handle to 1200 grit. Watco Danish oil for penetration, and then TruOil for the finish. It's a good looking blade, and with that thin grind, it shouldn't ever need thinning. Thanks for looking! I'm a little proud of this one. I hope it gets a blue ribbon and maybe a gold star!
. Amazing work.
