I am thinking about this as I recently waxed a strop and ironed in the wax to get it nice and stiff.

I got what I needed, but say on a snowboard or ski you scrape off the excess after ironing. This doesn't work as well on a strop.

The linen itself strops fine and I get good results from it now, but next time around I would probably just apply wax on the linen side that doesn't see razor action. I figure the strop will still be stiff, and I can scrape excess without worries, and the surface on the other side will stay as is. I am not sure if the wax has a special function for the edge (e.g. - does it have to be put on the side that the razor is touching? and am I losing something by applying it to the other side?)

Just sharing my experience, thoughts, and asking for some input - if anyone knows / cares

Cheers
Ivo
