Two reasons.

1) The Tomahawk is much more realistic in terms of killing power. An axe thrown at you is a damn sight more likely to kill than a knife.

2) I used to think the Tomahawk was a novelty until I put it on my sniper class. It wasn't long untill I realised the potential of it. With it, I was able to finish enemies off at medium range, a distance too long for pistols, but too short for sniper rifles.

However I do agree, that other than a bayonet, there should be no dedicated melee weapon.
