I always like to say that one test can fool you, so always do two or three tests. My three bevel tests are the arm hair test, the thumb pad, and the look test.

After 1k this is what i look for. The razor should cut arm hair effortlessly all along the blade with no pressure. The edge should feel super sharp and stick to my thumb. The edge should look polished without magnification; and under a magnifier the very edge should look very straight without reflecting light.
