Head Wrench ... aka the Mechanic at a Bike Shop. My boss says my hands are never clean. What can I say after 25 years fiddling with gears, shifters, hubs, wheels, headsets, bottom brackets.... if i get a cut probably oil and grease would flow out. Used to work in the IT dept of a major bank before I got bitten by the bike touring bug. Been around various countries by bicycle.
