There are so many options it is hard to choose!
If you asked me to pick the first knife that comes to mind, it would be the ZT0560 or 0561, and IMO it should be checked out before buying.
The highlights of this knife is both oversized thumb studs and flipper, the use of titanium alloy for the handle structure, G10 scale for grip as ti-only can be slippery, an overbuilt pivot and advanced bearing/detent system, a thicker locking bar, an unusually thick blade, and a blade steel of ELMAX in which a lot of independent testing speaks to this steel. Build purpose is really for heavier usage more so than fine cutting, although the knife is capable of both.
The materials used on it are notable for their toughness and longevity, and the lock used is designed for usage that many other knives would either not hold up to or not hold up to without developing something such as blade play. ELMAX steel is known for being tougher than most stainless steels and it gives excellent edge retention and corrosion resistance.
You will probably also want a knife in a brushed, stonewashed, or tumbled finish over polished or coated blade because the latter two tend to get marked up easily and are difficult-to-impossible to fix, where as brushed, SW, or tumbled can be refinished in a 20 second DIY job with a scratch pen or SC block. Also, it sounds like you may want to look for a steel that favors toughness over edge retention which is why I think that ELMAX is an excellent choice given the abuse it can take.
