A Keysaber is a weapon similar to a sword. It projects a laser beam that forms into a key shape. The typical Keysaber hilt consisted of a metal cylinder between fifteen and twenty centimeters in length. However, the size of individuals hilts varied drastically, as the weapon was tailored to the creator's specific needs and preferences. Even though the Jerdi were building Keysabers 2,000 years ago, nobody else knew about them (or how to make them) until Ed Island laboratories started experimenting with them in 1998.
Keysabers are extremely dangerous to use, since they are fatal and can slice anything in it's path due to it's strong concentration of heat. Penguins wishing to obtain these weapons must receive special licenses from their countries in order to legally own one, though many villains construct their own in secret or buy some from the black market. Due to the weightlessness of the laser and the strong gyroscopic effect generated by it, Keysabers required a great deal of strength to wield, and was extremely difficult—and dangerous—for the untrained to attempt using, meaning if one penguin had theirs stolen, and the thief tried to use it, the thief would probably get hurt. Despite this, they are very powerful, as they can deflect Deletion Lasers and destroy bullets and snowballs.
 Standard Keysaber
The most common as well as dangerous form of the Keysaber. It comes in a variety of colors. The standard original Keysaber is capable of destroying everything in it's path except living organisms (which it gives a small electric shock). Jerdi and Serth use normal keysabers as training weapons (and they use deletion keysabers as normal weapons).
This keysaber was created over 2,000 years ago by the Jerdi during the Land of Lord Guin. The weapon was cutting edge enough to overthrow the country, but because it was only limited to Jerdi, it's use was rare and eventually became a secret for a long time.
 Beginner's Keysaber
The second most common form of the Keysaber, this keysaber is not as painful and can only scratch a penguin when struck. Penguins taking the Battle Class in the Penguin University use these to learn.
 Energy Keysaber
A different version of the Keysaber is the Energy Keysaber which is a two-pronged version of it. Instead of the hilt projecting a single, key-shaped blade, an Energy Keysaber projects two, more rounded blades. This version is much more powerful due to it's blades being strengthened by electricity. Despite these improvements, it is vulnerable to being sliced down the middle by another Keysaber.
The Keydagger is a smaller version of the Keysaber which is often dual wielded or held upside-down.
 Phazon/Dark Keysaber
A Keysaber corrupted with Phazon. This version can actually grievously injure(Or even kill!) a penguin. The only known users are Dark Lorgas and His Elite Guard.
 Phazon/Dark Keydagger
A Phazon-Corrupted Keydagger. It is used By Officers in Dark Lorgas' Army.
 Deletion Keysaber
Deletion Keysabers are a rare but powerful variant of the regular keysaber. They can cut through anything like a normal keysabaer, but can also delete a target (living organism) upon striking them. The only ones made are being researched in Ed Laboratories. Jerdi and Serth also use these weapons.

 Background Music
It is common for penguins while dueling to turn on background music. Known duels with background music are:
- Race to Mars- While Swiss Ninja and Clovis were dueling each other.
- Barbearic Crab War- When Lane and Coldless dueled, and also when Ish2 and Coldless dueled.
