A quality strop is just that no matter the critter it comes from.
You're paying for the process used to make it and the fact it is handmade in low production. Is it different than a plain cowhide strop? yes it's more luxurious to use. Does it do a better job than a cowhide strop? No I don't think so and I have one.
I agree, and I have a 70000..Beautiful workmanship and hardware,
