A vibroblade is a class of science fiction weapon that uses an ultrasonic generator attached to a bladed weapon like a knife or sword. The ultrasonic vibrations along the blade's edge allow it to cut through much denser materials than would normally be possible. Alternatively, friction from the vibrations are used to heat the blade white-hot, and the heat is the source of the increased cutting power.
Darth Maul would probably win. He can't defend himself. And The force just makes it too difficult. I think Wolverine is a better fighter though.
