I'm trying to develop my feel for the TPT before I look like an olympic swimmer. The way I'm doing it is to wet my thumb for at least 20 second, then run it along the edge lightly. The edge passes when I can feel the blade grab the skin, as opposed to sliding easily along.

Assuming you start with a 1k, and go up through 4k, 8k and 12k, does the feel of the thumb pad test change from one grit to another? Once you have it at 1k, will it feel stickier, or dig in more on the higher grits?

thanks
