Abstract
A can opener has two relatively pivotable body portions (1,2), one carrying a rotary cutting wheel (8) and the other a rotary traction wheel (12) having parallel axes, the opener being arranged to receive the rim (R) of a can (C) between the two wheels and to orbit the can as the traction wheel is rotated while the cutting wheel makes a peripheral cut, the traction wheel (12) being shaped to distort the rim during cutting and the cutting wheel (8) having an outwardly angled body portion (10c, 10d), adjacent its cutting tip (10a, 10b), the angled body portion being adapted to contact the outside of the rim below the cut to exert a force in the opposite direction to the traction wheel (12).
