Hello all,

I picked up a 4 sided paddle strop this weekend, my very first paddle strop. This one is in reasonable shape (read useable). Each of the sides is numbered from coarsest to finest.
The number one side is actually a stone of some sort and that makes me wonder if anyone knows what kind of stone was used and the approximate grit.

The box says:

Razor - Strop Asentator
Streich - Riemen
Cuir A Rasior Made in Germany Cor (mouse bite)

On the handle it says :

Hirsch
