The vibroarm was a vibro-weapon that acted like a glove over the arm. The vibroarm was made of soft tissue on the inside with shock-absorbing materials. The outside was separate from the inside and was made of tiny microscopic blade edges all around. A motor powered by vibrating plasma vibrated the outer weapon and allowed it to act as a vibroblade. Because of velocity being unstable in this weapon, it was of little value and could not be bought for more than 2 credits.
