I managed to restrain myself for 6 weeks, using the free starter strop to learn proper stropping (proper meaning not slicing the strop).
But I finally used my 3" wide honey brown #1 heirloom.

The starter strop is a good strop and it gave good results, so I almost started thinking: 'maybe I should've bought a cheaper TM'

What a difference...

The feeling is totally different. I would almost say: stropping on velvet.
I am still convinced that the starter strop suffices, but the #1 is truly a work of art.
