Back luck on the scales Mate.

ok I know very very little about synthectics but heres what I do.

1, a coti with water will polish the edge as smooth as any other finisher, and will easily refresh a dulling (starting to pull) edge
2, a coti with slurry will cut as fast as a 1k, for real!
3, A yellow coti used both with slurry and water, and of course the right techniques will take you from a breadknifed edge through to the sharpest smoothest edge you could desire. however for real heavy work a 400/1000 is what I use, once the bevel is set enough to pass tnt then I am on to the coti all the way. I very very rarely use the BBW side of my beautiful stone, as I find I simply do not need it.

Seriously as said before in this thread, if you start with a sharp razor, draw the edge over a glass then follow Barts technique for the unicot method, you will have the finest smoothest shaving egde you could wish for, Honestly a 12 yr old with no experience could do it with the proper guidance.

Again I ask you to please just try it? it will take you an hour tops and give you a very simple straightforward method of getting a Razor very shave ready, what do you have to lose?

Best wishes and good luck, its a wonderful adventure that you have embarked on Greg
