the pure bred fighters are built like tanks - wich is fine for heavy use, and its fight for something to be used as a chopper - but for penetration it kind of hurts them.
they are massive not just for their spine thickness - but for their really low flat saber grinds that puts the metal behind the edge at somewhat silly proportions.
in order to bring the edge down to 21 degree's - you have to eat up the entire saber grind at the tip, and nearly 1/2+ of the grind on the main edge. and ONLY at that point would i suggest them at fighters - beacause otherwise the only thing you can really do with them is stab. mine wouldnt cut paper, cloth, or anything with a factory edge (wich was above a square (more then 90 degree's included)).
they are really nice knives - and im sure that they would perform wonderfully at their given task - but youd have to grind them down first.
the pbfs are one of the only busse knives (actually the only) that has length and a pointy tip. the nark has the benefit of being thin and inherently very very sharp (or easily made very very sharp) - and still stiff enough to take any kind of lateral torque or twisting. the serrated edge could easily be implimeted in any kind of trapping youd do with the blade, etc etc, but more then that the security of the handle,and the reletively pointy tip, and the thin edge are what put it above the rest for me (outside the reground pbf's)
the argonne assault custom with the tiger pattern serrations from hilt to tip is probably the most brutal of the designs i've seen, and the most fighter oriantated. any way that you hit the guy with that knife ,something bad is going to happen. the very pointy tip, serrated recurve, the steel knuckle gaurd, all add up to something that even if you suck with a knife, as long as you can keep that arm free and able to move (wich is difficult to do if you dont know how to fight to begin with) it will do damage almost any way you use it.
the pilot master - a serrated smooth choil transition version of an air rescue knife would make an excellent figher, though its slightly short. its pointy and fully serated, with no choil to catch on.
and theres always the striaght handled battle mistress
or even better - chucks machete!!!
