What is Keyblade?
1.
A Keyblade is essentially a giant key-like weapon. It can be used in many ways, like to seal the Keyholes of each world or to be used as a weapon. There are many people who wield Keyblades, but only Keyblade Masters, like Sora or the Unknowns from Kingdom Hearts 2, can use the Keyblades to their full potential.
"So, this thing is called a Keyblade..." -Riku
2.
A large key-shaped weapon. It has the power to unlock any seal or lock (Assuming the wielder of the keyblade was a chosen keyblade wielder). It is said it can bring both peace and chaos. When the keychain attached to it's rear is replaced with another special keychain, the keyblade may change form into a new keyblade. (Still keeping it's unlocking capabilities)
"So the keyblade can unlock ANY seal?" -Hades

1. A weapon from Kingdom Hearts, which is a videogame series by square enix. The keyblade can change forms as you progress through the game, giving new abilities to the wielder. In Birth by sleep The keyblade was a large part of the the keyblade war, and it is the main weapon in KH apart from the struggle bat. It is said to be able to open ANY seal, but in game the only lock you open is the key to another world; locked doors stay locked.
2. A big Fucking key that can open any lock, except the one the to the bathroom.
