Blade-based weapons

Blade-based weapons, or simply bladed 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 have the same functions as a true bladed weapon. Franchises bladed weapons are most commonly seen in are fantasy (swords, daggers, and axes) and horror (daggers, knives, and sometimes chainsaws).

Pros
Many bladed 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, bladed 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
Some bladed weapons 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, bladed weapons are often weighted, making accidentally tossing them with a weak grip a common mishap. Although not every bladed weapon deals with the issue, most are short-to-mid-range, meaning unless they have a certain special ability, they're totally useless against enemies who are far away.

In battle
Almost all bladed 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 bladed 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 bladed 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.
