I'm looking to buy a good stop. I'm not good at stropping myself, but I want there to be no question about whether or not my deficiencies are the result of a bad tool. I want to take that uncertainty (however remote it may be in reality) out of the picture so I can focus on improving.

A recommendation would be wonderful. However as I don't 'know,' strops I'm looking for, let us say, a strop which is to stropping what a Norton 4/8 or Naniwa SS hone is to honing. Something ubiquitous and well-liked.
