Vibroknives were the first mass-produced vibro weapons, and are the standard by which all vibro weaponry is judged. Little more than a combat knife with an onboard ultrasonic vibration field generator, the integrated ultrasonic generator causes the knife’s blade to vibrate at incredibly high frequencies, greatly increasing its penetrative and destructive potential. They can saw through most materials, are easily concealed, and offer their users even more versatility than a standard combat knife.
