Detachable Blades

There's always a spare blade.

Most swords and bladed weapons suffer from the problem of breakage, and it takes regular maintenance to keep it in a good condition, either sharpening it or outright reforging it, not only it is time consuming, no matter how regular you repair them, your blades will inevitably break. So why bother keeping the same blade?

Enter the detachable blade, a type of bladed weapon which can detach its blade from its hilt and swap for a new one. As long as you have a hilt and spare blades, there's no need to sharpen your blades. Simply toss the old blade away and put on a new one, and here it is, a brand new sword!

Some weapons with detachable blades take one step further by launching the blade towards an enemy. As not many people would expect a sword to shoot its blade, it serves as a great tool for a surprise attack, a bayonet, or a weapon for killing someone afar stealthily.

Compare Bifurcated Weapon, a weapon built by attaching with multiple weapons, in which they are naturally detachable for another reason. See also Detachment Combat, Feather Flechettes and Spike Shooter.

For firearms counterpart, see Throw-Away Guns.

    Anime & Manga 
  • The Vertical Maneuver Gear from Attack on Titan features a pair of dual blades, with their grips serving as the control of the hooks. Soldiers usually carry multiple blades in boxes built at the sides of their thighs, and the blades are swappable in case one of them gets stuck on a titan or broken.
  • Gundam Vidar's Burst Saber from Mobile Suit Gundam: Iron-Blooded Orphans can disconnect from its hilt and serve as an explosive should it gets stuck onto an enemy. The Vidar carries 6 spare blades in total and its pilot, Gaelio Bauduin, utilizes it in its full potential with his agile combat style.
  • Miki Sayaka's cutlass from Puella Magi Madoka Magica, according to the production notes, has a trigger which can either turn it into a Whip Sword or launch and detonate the blade. While it is Dummied Out in the anime, it is used in a cutscene of the SLOT Puella Magi Madoka Magica slot machine, where she launches the blade towards a barrel in a Pop-Up Pirate-esque minigame to send Kyubey out of it. Unlike most examples, Sayaka simply summons her swords instead of swapping the blades.
  • Slayers: Gourry disguises his legendary Sword of Light as a normal sword by keeping its Laser Blade turned off and socketing a common steel blade in its hilt. In a pinch, it can be removed by tapping a needle to a hidden spot on the hilt.
