Ahso .... a fellow strop acquisition disorder sufferer. :) Well I have the Premium 1, a couple of TM top of the line strops and a dozen vintage strops. I recently couldn't help myself and got a Keith De Grau signature and a Chicago Special from HandAmerican.
These are wild strops. Like anything Keith makes they are top of the line in quality and workmanship. They are very stiff because you have two regular thickness strops glued back to back. They are sort of like stropping on a board but they are really gorgeous and I will be working with them to try and figure where they fit in. If your a strop freak put them on your to get list for sure.
