dirty-handed

Unwashed after work

Dirty-handed describes someone whose hands are physically soiled, or more often, someone who does hands-on work that leaves them that way: The dirty-handed mechanic wiped grease on his jeans.

Figuratively, it can suggest involvement in unsavory dealings, though dirty-hands or dirty hands is more common for that sense.
