A "fighter"?
When our son was in a serious training cycle at 29 Palms prior to "surging" into Iraq in 2004, I bought him a series of serious knives suitable for a warfighter about to go into harm's way in a hot combat zone. Several were genuine fighting knives; an Ek dagger, a Darrel Ralph designed folding dagger, a Randall #1"All Purpose Fighter" and others.
What he took: The Randall and a Chris Reeve "Green Beret". When he deployed a second time, he only took the CRK because it was better at doing the things he really needed to do . . .which was not fighting. Later on, safe at home, he said that the CRK seemed to be more rugged and that lacking that knife, he would have taken a Ka-Bar "Extreme Survival", a modern iteration of the iconic USMC issued knife from WW-II, Korea and Viet Nam. . . .for the same reason. . . .and at 1/3 the price.
Reexamine why you want a "fighter". If it is to have and hold at home . . .well OK, I get that. But if you think you need it for self-defense in a civilian setting think again. Think about where you are going, what you are doing and who you are with.
