Every 4 or five months I take my blades back to 1 mircon diamond film,occasionally if it's very bad I'll bring to the Naniwa 8k. I don't finish my edges on a stone but on the .5 diamond 3m flim.

I use the CROX even after the .5 diamond to bring the razor into a more comfortable zone, then strop 100 laps on the leather, to bring into that light saber zone.

I think once you find what you want from your edges then it will be much easier to say if you will be bringing them back to an 8k or even a 12k.

I bring my back because I have a very coarse beard, and despite great prep shaving everyday takes a little bit off some of my blades.


good luck
