The main thing to remember is that when you are buffing a full hollow with greaseless, you do have to be very light on the touch as well as keep the blade moving. Even with that on some of the old thin blades, they will heat up in an instant. I sometimes just back off after a second or two on the wheel and constantly keep an eye or finger out to feel for warming. I will dunk frequently on these as it takes just a second of not paying attention to get a burn spot on the razor. Once you do a few you get a much better feel what what is going on and what the guys are talking about becomes second nature.

Have fun,
