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. Weapons like swords, knives, and rapiers are great at piercing through soft armor and clothing, permanently damaging whatever they struck and making the enemy more susceptible to future attacks. With the exception of explosives, blade weapons are the most violent weapon type, being able to decapitate, disembowel, and dismember their foes, killing them the fastest in a gory battle.

Cons
A bad part to blade weapons is that they can easily hurt their user, especially a Jackass, Clutz, or nearly anyone else who doesn't have what it takes (responsibility) to wield such a harmful weapon. And as they are melee weapons, blade weapons are often weighted, making accidentally tossing them with a weak grip a common mishap.

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 unless they can Boomerang Anything.

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.
