I'm attempting to venture in the fixed blades myself, after playing around with multi-tools (use LM Fuse) and numerous SAKs (Huntsman, Manager, Craftsman.
The Becker Crewman (BK10) looks great, but I heard that the sheath is kinda cheap. I'm also considering the SOG Seal Pup, looks like a great knife too (<80$ knives) but the plastic sheath looks a little cumbersome... Anyways, between those two, I might be slowly going towards the SOG Seal Pup. Sounds like both of these could be used here by the original poster of this thread.
This is not to EDC of course... I EDC my Huntsman along with a Micra on my keyring.
