That is great for knives and the lovely hollow grinds they often get. You have all seen vids of harmonic vibration getting out of control. If a thin razor "sings" that is vibration and if it happens during a grind the sing is modified into a harmonic oscillation which, unfortunately will twist and wiggle the blade. When that happens, the blade will basically explode. The touch of a master grinder detect any vibration other than abrasion and modifies the stroke and speed of advance. A pre-hardening grind would be a different story and the metal is not hard.

So even renewing a blade, if I hear a singing I "STOP' and do a different approach.

Here's a video of the singing vibration on a plate. Imagine a XXii razor!
