That is beautiful!
I have a strop from Capid1 sprayed with .25 and .125 diamond and it works like crazy! Excellent for putting that final polish on the edge or touching up a user when you don't want to stop and resharpen. A few swipes and back in business. Awesome for the leatherworking knives also.
I used to have a typical strop loaded with buffing compound and the diamond/cbn sprays totally smoke them...especially on the hi wear super steels.
