Mechanic's Grip ( poker )

A way of holding the cards popular with mechanics, because it's easiest to deal seconds, bottoms, or middles when holding the deck this way. A right-handed dealer holds the deck in his left hand, with the thumb along the left edge, the forefinger at the front, and the other three fingers curled around the right edge.
(A left-handed dealer does the same, mutatis mutandis, with his right hand.)
Since many no cheating players also hold the deck this way, the grip alone is not evidence enough to accuse a player of cheating.
