Yes maybe it has been answered many times, thing is I could not find a thread that specify clearly why the strops have a linen side,, what is its purpose?? when should I use it?? where the Crox should be put, on the linen side or the leather side?? what is the difference when you put it on each part of the strop??? I hope someone can guide me on this or give me a link to a specific thread... thank you all
