I'm not sure of prices, that and I understand at least one of the maker's is no longer taking orders . . . and feel free to swap price categories if I'm way off . . . but . . . $1000 Phil Wilson Utility knife around 3.5 to 4 inch. Very thin behind the edge (.004" to .006"), not very wide and about 2mm at the spine. His famous CPM 10V or I'd even settle for his M4 . $2000 a custom Large Single Blade Trapper from Tony Bose or T. A. Davidson off the exchange in the best steel I could get and or sneak a Phil Wilson blade into the Trapper (as if that were even any kind of a realistic option). Ebony would work or Black Water Buffalo horn etc. I hope that's not too far off the mark of what you asked for. Other than those I have about all the knives I could ever want. . . . well there's still that antique, well carried and used but in great shape, Sunfish that I have always wanted. Complete with provenance of the workman (workmen) that have carried it; where, when what their work was etc. A few weeks ago I stumbled on some such and I think I saw prices well above $2,000 ! That sucks because I really wanted to have one some day.
