A heavy duty industrial can opener operated by hand or by motor which accommodates various sizes of cans and cuts the outer seam wall of a can rather than the top lip of the can. The can opener includes a cutting wheel with a cutting edge and a traction wheel with a gripping surface. The cutting and traction wheels each have associated gears for rotating the wheels. The gear for the traction wheel is releasably engageable with the gear of the cutting wheel. One of the gears is driven to rotate both the cutting and traction wheels. A cam lock provides a series of levers and link pins the ability to releasably engaged and disengaged the gears. The distance between the cutting wheel and the traction wheel is automatically adjusted while the cam is locked in place.
