Rusty, this appears to be legal to me.
A knife is a vital component to an EDC. They are lethal self-defense weapons and are every bit as deadly as a firearm. You may already have good experience with edged weapons, but in the event that you don't, please consider getting some training. It is very common for folks to get stabbed by the same knives which they introduced into the fight.
I am a bit of a knife geek, and I always carry a working knife and a defense knife. Some of the things I look for in an EDC fighting knife:
a) I try to find a decent steel blade. I like 154CM or D2. CMP3V is excellent. Better steel can get really expensive however. There are a lot of good blades made with 1095 high carbon.
b) I don't want a fighting knife that is too long. 4 inches is kind of the sweet spot for me. Effective knife work involves not displaying the blade until the cut is being made and anything too long is hard to cloak.
c) Full tang construction is vital. You don't want the handle breaking off in a fight.
d) I like a slightly oversized choil to allow me to choke up on the blade.
e) I largely stick to drop point blades. I have seen some guys do very impressive demonstrations with exotic designs like the karambit, but I ain't one of those guys.
Knife guys are like gun guys. We all have our own specific criteria and baked in opinions!
