The laser scalpel is a Cybertronian medical tool, used frequently by Ratchet.
Marvel Comics continuity
Our intrepid laser scalpel aided Ratchet's escape from pursuing police cars, before joining forces with the villain known as the Mechanic.
The laser scalpel's career highlight may have occured when it was used to take down the battle droid Guardian, with perhaps just a little help from Ratchet.
