Well, I just treated myself to a high end strap for personal use!
I purchased the #60000 from JimR at Kanayama Cordovan Strops
At 4mm thick (~.15"), and 66cm long (~26") It is a great size.
I have heard great things about the kanayama cordovan leather, and eagerly await its arrival from JimR. I already own a linen component which I attached to my vintage shell strap, and the linen is simply fantastic. I really love it. Very stiff, and seems to put a great finished edge on my shavers.
I will post my thoughts here when the leather arrives, in the meantime, post yours if you have used!
