Blade-based weapons

Blade-based weapons, or simply blade weapons, are weapons that have at least one blade, like a sword or dagger. Although the general description of a "blade-based weapon" is exactly that, UnTrash Wiki allows exceptions like chainsaws (having teeth) and axes (having edged heads) that don't have true blades, but can still be used like how a true bladed weapon would be.

Pros
Many blade weapons, or melee weapons in general, are mid-weight or heavy and can deal lots of damage in few hits. They're best when paired up with a user who cannot deal much damage on their own, can move quickly, or can handle heavy weapons.

Cons
A bad thing about blade weapons is that they can easily hurt their user, especially a Jackass, Clutz, or pretty much anyone else who doesn't have what it takes (responsibility) to wield such a harmful weapon.

In battle
Almost all blade weapons are purely melee, meaning they must make physical contact with their target to inflict damage, unlike a ranged weapon, which can be used from a distance on a target. Some blade weapons are small and/or light enough to be thrown at the target to be used effectively, but will not return to their thrower like a boomerang.

As tools
Some blade weapons can double as tools for survival, like daggers and axes. They can be used to chop wood, kill animals, and ward off enemies like dangerous animals or hostile survivors who will kill others for their own good.
