if you plan to get it sharp on only one stone the belgian coticule would be the best choice.
otherwhise your best option is to utilize the services of one of our highly skilled guys.

btw, the best stropping is on horse butt. i wonder if it works just as good when the horse is still alive... it almost looks like a potential catch 22 - to make a strop from the horse you need sharp razor, and to make the razor sharp you need the horse to be strop...

do you use sword at work?
