ok, here's the story....

I have several strops, one looks kinda like untanned or lightly tanned, or more raw, attached to a highly tanned black strop that is very slick and hard.

The dope I bought the strop from folded it and shoved it in a box, wrinkling the raw hide looking strop. The hard leather strop survived the fold, amazingly. So I just purchased a 'Big Daddy' from another shaving shop.

The 'Daddy' has a felt or canvas strop with the leather strop.

Here's the unanswered part of my question....

Which do you use when and why? Do you start on the softer and work to the slicker (harder) leather. Start on the felt (wool, canvas, whatever) and then finish on the leather?

Common sense say's to use the softer, move to the harder, but why would I need more than one? They sell them together so there must be the intent. I'm just not sure I get it..

Thanks!!!
