You'd think they might suck the innards out of a wire. And you'd be wrong. Vampliers are actually on the job to remove your rusty, stripped, damaged, jammed, or tamper-proof screws. And how do they do this, you ask? With vertically and horizontally serrated jaws that bite into nearly any surface without slipping or stripping the screw. Just try not to use it for normal plier-y things that you don't want to take a bite out of — something tells us they might leave a mark.
