<p>The can opener disclosed comprises a pair of handles which are hinged to one another and which are movable between an open position for fitting onto a can and a closed cutting position. A manually rotatable drive wheel engages the rim of a can and upon rotation advances the opener around a can bringing a knife to a cutting position relative the drive wheel as the handles are brought to the closed position. The knife is a circular cutting wheel (16) rotatably mounted on one handle (12) with its axis displaced from the axis of hinging. The other handle (14) has an upstanding cylindrical spigot (26) extending through a corresponding hole (28) in the said one handle (12) and about which the said one handle (12) is hinged relative the said other handle (14). A support (23) for the drive wheel (20) passes through and is rotatably born in the spigot (26) with the axis of rotation of the drive wheel (20) displaced from the axis of the spigot (26). Such a can opener will provide a good clean cut even if the can is damaged.</p> |
