You really should be able to have a BBS shave from the Norton. It can be done. One of the major keys is beard prep. Do not skimp in that area. Tha being said the next step in sharpness will come from a 0.5 micron pasted paddle strop.
After you experience that level of sharpness then you will start focusing on both the sharpness and the comfort/smoothness of the shave.


Good luck!
