A pilebunker is a tool or weapon composed of a pneumatic or hydraulic piston connected to a spiked shaft and recoil springs; Uses rapid compression to drive the piston forward which in turn drives a spike into an object, in a matter similar to that of a pneumatic hammer (jackhammer), only the spike goes far into the object and then retracts quickly, readying itself for another strike.
