Abstract: The invention is a sturdy shield with a generally U-shaped curved piece adapted to fit for several inches along the underside/little finger side/ulna side of the wrist. Near the middle of the U-shaped curved piece is a generally perpendicular ridge, or striking edge, depending vertically between about 1/4" and 3/4", and extending horizontally between about 2" and 6" along the length of the wrist. The U-shaped curved piece is secured to the wrist by any sturdy conventional means, for example, by an adjustable strapping means which passes over the top side/thumb side/radius side of the wrist. A shorter, wristwatch style is envisioned, as well as a longer, forearm length version.
