ABSTRACT:
A utility hand-piece is adapted for being worn on a hand of a user. The hand-piece includes a body portion adapted for covering at least a portion of the hand, and incorporating at least one fluid channel. A fluid inlet is formed with the body portion and communicates with the fluid channel. A fluid outlet is formed with the body portion and communicates with the fluid channel downstream of the fluid inlet. Upon connecting a fluid source to the hand-piece, fluid is transferred from the fluid inlet through the fluid channel and dispensed from the body portion through the fluid outlet.
