Alright, I've got a blade that is stumping me.

I've set the bevel and gone to the 4k. Now I am doing test shaves on my arm and when I shave with the back of the blade up (hold in right hand, shave back of left hand) I don't get any hairs to pop. When I shave with the front of the blade up (hold in left hand, shave back of right hand) hairs fall off before the blade even gets close to them its so sharp.

I've tried going back to the 1k for 20 - 30 more laps, followed by ~50 laps on the 4k. I still have the same problem.

I use 1 layer of tape on all of my razors. That shouldn't be a problem.

Suggestions anyone?
