Oh, I see what you're going with now :P
And you know... To go with this, why don't you make a Tomahawk?

I confess I've never used the combat knife, so I don't know how you would make this perform. But it would be cool to go with these bows. Plus there is only 1 melee
Actually, I only used the combat knife two or three times. One time all my weapons ran out of ammo, switched to the knife and ate lead D:
If it could have been thrown, I would have survived... damn, I have to add that!Maybe also because of the fact that I try to avoid close-combat because I'm not good at that. If suprise is on my side and I'm not outnumbered, I'm good :P
And yeah, that Tomahawk (combat axe, lol) on that pic would fit very well :3
Maybe instantkill on head? Of course when thrown instantkill :P
