🔥 Does Sharpening Damage Heat Treat? Thermal Camera Test Reveals the Truth!

In this video, I put the old myth to rest—that sharpening with belt grinders or machines like the Tormek with CBN wheels and no water ruins a knife’s temper. Using a thermal camera, I show exactly how much heat is generated during real sharpening sessions on both high-speed and low-speed machines. Whether you're a knife maker, sharpener, or just curious about blade performance, this test will give you the facts—visually and scientifically. No fluff. Just results. Watch and see what’s really happening to your blade's heat treat! Discount Code (5% code: VEVT5) Vevor Thermal Cameras: I GOT #1 in my list but they have a few.
