I could not find a sword frog that suited me so I cut up an old weight lifting belt and made this. The outer surface was black but the edges were raw leather...cured that with a fat black sharpie. Cut the leather with a raiser knife, drilled the fastening holes with a 3/16 drill bit then installed 3/16 x 1/2" binding pins.....thank God for keeping junk and Home Depot.....lol
Cheap camera so I outlined the frog to make it easier to see.
