and get them all to equal sharpness and smoothness.

This is a good challenge, I think. However, as vigilant as I am about creating consistently high quality edges, I find that it is really technique that’s required to get a great shave from different razors. With the sharpening process that I use, I can get edges on varying steels to perform almost identically in sharpness testing, and to look almost identical under high magnification. With this as a given I have found that I need to adapt my technique to get each razor type that I use to perform (for me) optimally.
