You're comparing apples to oranges. I'm not a " sebenza guy" either. I just bought it. It seemed like a very nice knife, so I bought one. I may buy a strider someday for different applications. When I pull that small 21 out in a public area, I get fewer looks then if I bust out my zt 560. I will use that knife, I'm not a collector. I won't use it as a pry bar, or to try to cut a car door in half.
Plus, it was brand new, out of the box for 2hrs, $500, and being used in a way it wants intended to be used.
Enjoy your strider, I hear they're great knives too.
