Well, if only framelocks, and only Ti handles, get yourself a Buck 172 Mayo. You can get them used sometimes, still for not a bad price if you have to buy online. As for Rick's knives, while I wouldn't hesitate to use them, you won't be able to use Rick's knives for a task you won't use a Sebenza for. If I had both, I'd use the Sebenza in a heartbeat b/c I just wouldn't care what happened to it. NOT the same with a Hinderer. Great knives, and definitely users, but c'mon, if you can't think of using a plain grey handled Sebbie for cutting cruddy stuff, how will you feel about one of Rick's beautifully anodized knives? 172 seems to make the most sense for your application- IF you can't use fixed blades. If you CAN use fixed blades, try something like the Becker Necker or a Swamp Rat. You can pry with the swamp rat, and its a good steel. Why do y'all think I carry fixed blades??? I'd carry a SR if they'd make something in the 3" range. They don't, though.
Sincerely,
Anthony
Edited to add: "Best" is what's best for you and your application. My "Best" comes in the form of a Fixed, locking folder, AND slipjoint. That's just me.
