I don;t know the Kershaw model or the Striders, I haven;t handled either. But I'm partial to Benchmade.
That Skirmish is a beautiful knife... but it's huge. It's a frame lock and has no thumbstud. These things you already know, I bet. I like it, but after playing with one for several minutes, I began to think it was a mite too big. I like the Mini-Skirmish but haven;t held one yet. Another thing I like about the Skirmishes is that they're "realtively" thin, and they have smooth scales. I carry a big knife every day, BM975, it's thin and smooth. I can;t imagine dragging that thing out of my waistband as often as I do if it had Presidio type scales.
