1. CRKT M16-02
2. Benchmade Griptilian
3. Jury is still out on a fixed blade. Maybe a Benchmade #162
The M16-02 is a knife that I carried for years while in the service. Not the greatest knife, but I am used to it. A SAK would be better, IMHO, but the 16's blade is easier to deploy.
I am not real crazy about the Griptilian but I find the one I own gets carried more than anything else I own. Bought it second hand for about $20. I think I did OK.
