WIRE WHEEL:
Cleans paint off bolts and then throws them somewhere under the workbench
with the speed of light. Also removes fingerprints and hard-earned calluses
from fingers in about the time it takes you to say, 'Oh sh -- '
Also sharpens the edges of flat-head screws just enough not to be noticed until you look at your fingers hours later and wonder "how the hell did that happen"!!
(Ask me how I know!!!)
