I'm generally quite happy with the shaves I get now but one problem is puzzling me. Using two good quality razors. One feels sharper than the other.

Shaving with the sharper feeling one, the beard feels as if it is cut easily, especially around the chin area. However, I'm almost always left with a few minor nicks despite the comfortable shave.

Shaving with the blunter feeling razor, the sides are fine but the razor pulls noticably around the chin. However, I almost never cut myself with this one.

I'm stumped, to be honest. Does anyone have any suggestions as to what the problem might be?
