Thread: My uncle the barber and TNT

I'm currently in barber school, and my two head instructors are in their late sixties and late eighties, respectively. Anyway, the TNT is the only method that these two gentlemen will use to test the edge of a razor. I've tried showing them the TPT, which I personally have the most success with, but they don't like it-- it must just be an old school barber thing.

Anyway, DoubleO explained exactly what I look for in a TNT, and how I use it. I personally never do the TNT past the point of bevel setting, after that, it's TPT then the shave test. Hope this helps.
