I use the TNT when setting the bevel. Once the bevel is set and I can see through a 30x eye loupe that it is uniform and all the same color I no longer use the TNT. I go to the TPT. This was taught to me by Randydance and it has worked very well. I also might mention that as a persons shaving technique improves with practice the shaves will get better.
An inexperienced shaver who is not familiar with skin stretching, manipulating the razor, and blade angle may get a poor shave from an shave ready razor. Be careful stropping as well. A shave ready edge can be ruined in a stroke on a strop if the strop is not held taut and the spine kept flat as you turn the blade. Lotta info in the Wiki tutorials. :gl:
