I like spyderedges very much because not only the cut well, but because, in certain ways, they are much more "tolerant" to non knife people abuses than a plain edge.
I say more tolerant, because I really like the polished edge i put in my plain edges, and sometimes (basicaly everyday) people asks me my knife to do something, and they generally use it in the way I would´t. So I lend them a SE endura with no regrets
And one more thing. People usually believe that a SE will do much better on cutting rope than a PE, but every year, when the hunting season starts, I have to cut lots of nylon ropes around the fences
Well, as much as I prefer a PE knife for my use, I always carry a SE with me and I really really would like to have a SE Para 2...
