Kmar, I have NO evidence to support this, but I think that MOST manufacturers get the "Fighting Knife" thing wrong. A fghting knife in my opinion is one that should excell in cutting flesh and perhaps clothing items and nothing else. In that Vein I think it should have a very thin, rather delicate edge. I personall think that MOST of the companies that advertise their product as "a FIGHTING KNIFE" are trying to cash in on a trend/fad, fear. What they are presenting many times is a TOUGH, strong and sturdy "Combat Knife" if you will. Something that we would probably call a good strong sturdy EDC blade.
This is just MY take on this. No animals were harmed in the thought process required to produce this post.
