ABSTRACT:
A folding can opener and an improved method for opening cans are provided. The can opener includes a handle; a cutter pivotably mounted to the handle; and a locking mechanism for the cutter. The cutter can be locked in an operating position in which a pointed tip of the cutter is adapted to pierce the can. The cutter can also be locked in a storage position in which the pointed tip is folded towards the handle and shielded by the handle. The locking mechanism includes a barrel cam formed on the cutter and having a lug for engaging a seam of the can and pairs of indentations having camming edges. The indentations are adapted for mating engagement with pawls formed on the handle (or separate pins placed between the handle and cutter). The handle is formed in a wish bone shape which permits the pawls to flex to allow engagement and disengagement of the pawls with the indentations. The shape of the indentations and camming edges allows the cutter to be locked in the operating or storage positions but rotated by a user between the operating and storage positions.
