Want something interesting, pick up a CRKT Graphite - about $40, give or take. Something about the Klecker lock just fascinates me; it operates just like a lockback, but using only the handle scales. Also, it's the only lockback design I've seen with a flipper, and the IKBS on such a cheap knife is awesome. I just wish the blade stock was a bit thinner, like the NIRK Tighe - it makes the knife a bit heavy and hurts cutting performance a bit. Still, I find it aesthetically and functionally intriguing, and it's one of only a few production NIRKs (all CRKT), with the custom world being exclusive to Brian Tighe as far as I know.
