I sent a knife design to Gayle Bradley a few years ago and asked him to make his interpretation of it. Before he sent me the knife, he cut a second blank of the pattern (CPM M4) and heat treated it the same way he did my knife. He applied 1,000 lbs of pressure across a 3” span of that blade with an arbor press, then used a cheater bar to increase pressure until it snapped at an estimated 1,700 lbs. The grain structure at the break was as pure as it gets. I’d never had a maker go to those lengths to test the heat treat on a new design before. Really impressive integrity and gives me so much confidence in the blade.
He was one of the founders of Bladesports Int’l and held several cutting records at one time. I can certainly see why—and how! Now of course he’s known mainly for his design collaborations with Spyderco.
The point being, true high-performance blade makers test and test and test again, never taking performance for granted.
