Some might say Sword of Omensa

Over glorified Swiss army knife.
It could only grow and turn into a pair of binoculars.
Myself would go for He mans sword of power

He-man's sword channeled the power of castle greyskull and changed him from Little lord Fontolroy to an Over sexed Uber Homo-Erotic Behemoth with a giant fúck off green tiger with S&M armour.....now that my learned friend is a Sword.
