Fixed blades? Probably something from CPK or Busse. Folding knives, probably the Cold Steel 4Max. There are plenty of niche, or limited run folding knives in 3V, but the issue will always be the pivot, so as long as the steel is at least decent it's really a secondary concern.
Plenty of guys making super big chunky folding knives (like Medford, as someone else mentioned), and others all the way into the custom scene where you will pay massive cash. Also, there are a TON of custom makers out there who make insane impossible to break fixed blades, but you will pay accordingly. If you don't like Busse or CPK because they don't weigh enough to suit you, there's always Miller Bros for example. LOL
If money is truly no object, then you should research makers and have someone make something for you to your exact specifications.
