thats 3 tads to a bit and 4 bits to a little, right?
On the issue of sharpness-sharp is sharp the size of the razor has nothing to do with relative sharpness. If its sharp a 3/8s will shave just as good as a 7/8s. I would wager a bet that if I took an 8/8s razor and a 2/8s razor of similar grind and equal sharpness and put just the edge under a microscope you couldn't tell which was which and that is what your beard sees.
Obviously some thing is askew in this case. maybe that warp?
