Hi there,
It sounds like you already have your mind made up, but if not, why not consider something like a CRKT M-series knife. They come in a number of sizes, blade configurations , handles and prices. I have a small CF m16 tanto blade that has served very well. I have used it at work, mountaineering, sea paddling , adventure racing and everything else I do with no complaints. This little guy has cut everything from climbing rope to seatbelts, double-jacketed fire hose to the rubber trim around car windows and has always come back to solid sharpness. I can only imagine what the larger models would do. You would quite a bit of money as well. Good luck.
