Abstract: A can opener has a first and a second handle member pivotably connected to be moveable between an open disposition and a closed disposition. They can be squeezed together in one hand of the operator to rotate a drive wheel. A cutting wheel is mounted onto the first handle member. A radially facing aperture is formed through a part of said first handle member so that the drive wheel may partly protrude to engage the rim of the can and press it against the cutting wheel. The drive wheel is mounted rotatably onto a rivet which is held slideably in a slot in the main plate of the first handle member to be moveable towards and away from the cutting wheel.
