Hello Gentlemen!

I’ve done about 10 to 15 shaves with the straight now.
My strop has leather on one and a rougher material on the second stop. The backside of the second strop has chromium oxide powder on it.

What is the recommended routine of stropping when using the chromium oxide?
For example, how many shaves do I do just using the rough strop followed by the leather strop before moving on to the need to use the chromium oxide side of the strop?

And, once I use the chromium oxide side of the strop, what is the actual routine and how many strokes? Do I follow it with leather stropping and how many strokes for that? Or do I follow it with the other rough side of the strop before leather stropping it and how many strokes for that?

In short, what is the routine when using the chromium oxide side of the strop?
Thanks again for your responses!
