ABSTRACT:
A flat rigid rectangular plate has four corners bent down to form rigid V-shaped points to grip on an ice surface. The plate is larger than an adult hand and serves as a hand-held paddle in water. A longer spike or triangular point extends away from the plate at a right angle to the V-shaped points for gripping an ice surface through a snow cover. A handle extending from the top of the plate maybe equipped with a safety cord to loop over the wrist of the user. The handle may be permanently upright or foldable.
