well i wouold choose the boomerang for a long range melee weapon and and a machete for close range cause you just cant beat its slicing power plus its a classic melee weapon right up there with the butcher knifa and katana
Tomahawk, I've seen a variety of awesome pre-gunpowder weaponry, but the Tomahawk serves as both a throwing weapon capable of cracking one's skull open and a more than able melee weapon for close quarters.
We all know that shovels are the best weapons. And if having extreme chopping prowess isn't enough, you can tomahawk people with them if your at a range.
