A can opener comprising a housing having a handle. A cutting wheel having a cutting edge for severing a can wall is mounted in the housing. There is a traction wheel having a gripping surface to engage the can. The traction wheel are rotatable and the axis rotation is substantially perpendicular to each other. The wheels are positioned adjacent and spaced apart from each other to define a gap to accept a can to be opened. One of the wheels is movable towards the other to engage and lock the can between the cutting wheel and the traction wheel. The cutting wheel then acts to sever the can wall and the traction wheel acts to move the can past the cutting wheel. There is a first thrust surface associated with the housing and a space, adjacent, second thrust surface associated with the movable wheel. The first and second thrust surfaces comprises cooperable can surfaces rotatable relative to each other to reciprocate the first and second thrust surfaces relative to each other between a first position where the gap to receive the can is relatively wide, and a second position where the can is engaged and locked between the cutting wheel and the traction wheel. There is a handle to permit one of the wheels to be rotated by hand.
