There are so many choices out there it's mind boggling.

Now I have a quality strop from the Premier Strop Company so it's not that I need a good one. But what are the differences?
I see threads about the Kanayama and many other higher priced strops, now there has to be a reason there are so many.
Do you get a better edge with these higher priced and I assume quality strops? I'm sure the craftsmanship is above your lower to midrange strops, but are they seriously worth the extra $$$$
