I wanted a small box-cutter that wouldn’t rust, Blade HQ helped me out with the Stedemon Knives Mini-01, a Titanium frame lock with CTS 204-P blade steel that is thick, has a nice point on it, and should hold a great edge.
Very unique flipper, with the flipper mechanism on the end of the knife where it doesn’t exactly show itself for what it is. Pretty clever, nicely made, ceramic bearings and ball detent. Quick and easy to use, small and unobtrusive in the pocket.
The S731 is a slim, elegant knife. It weights only 75 g /2.64 oz/ (117 g /4.12 oz/ with the sheath).
The S745 is a different category, according to its specs that’s a heavy duty beast.
