taining the cutter in either its operative or inoperative positions.

For assisting in moving the cutter from its inoperative position within recess 19 to its operative position a fingernail receiving recess 27 may be provided in the handle portion, whereby a person 'may insert a fingernail or a sharp instrument between the cutter 16 and the body for raising the cutter to its operative position.

It Will be noted that the depression may be formed by a stamping operation which would result in a slightly raised rib 28 which provides additional strength to the structure and an opening 29 may be provided in the handle for attaching the device to a key chain or the like.

It will be obvious to those skilled in the art that various changes may be made in the invention without departing from the spirit and scope thereof, and therefore, the invention is not limited by that which is shown in the drawings and described in the specification, but only as indicated in the appended claims.

4. A can opener comprising a body of sheet metal providing a handle, a cutter having an integral pintle, a curved hinge strap extending from one edge of the body engaging the pintle of said cutter, said handle being provided with a recess for sheathing the cutter in inoperative position, the interior of said hinge strap and the pintle being of non-circular outline and constructed to maintain the cutter in sheathed position within the recess in the body or in its operative position, said body being provided with an indentation for receiving a portion of the hinge strap and for strengthening the handle, stops on said cutter engageable with the said one edge of the handle for limiting the movement of said cutter, the said one edge being provided with a'can lip receiving notch, said cutter being provided with a recess for receiving a fingernail for raising the same and said handle being provided with a cooperating recess to facilitate the insertion of a fingernail or sharp element between the cutter and the handle for raising the same.

5. A can opener comprising a body of sheet metal providing a handle, a cutter having an integral pintle, a curved hinge strap extending from one edge of the body engaging the pintle of said cutter, said handle being provided with a recess for sheathing the cutter in inoperative position, the interior of said hinge strap and the pintle being of non-circular outline and constructed to maintain the cutter in sheathed position within the recess in the body or in its operative position, said body being provided with an indentation for'receiving a portion of the hinge strap and for strengthening the handle, stops on said cutter engageable with the said one edge of the handle for limiting the movement of said cutter, the said one edge being provided with a can lip receiving notch.
