A can opener has a cutter blade mounted with a body and a traction wheel mounted with the body on or adjacent the cutter blade. One of the cutter blade or traction wheel is movable with respect to the other between an inoperative position and an operative position. In the inoperative position the traction wheel and the cutter blade are spaced apart so that a rim of a can to be opened may be located between the traction wheel and the cutter blade. In the operative position the traction wheel and the cutter blade engage a can for opening the can. The can opener has an operating element that is operable by a user of the can opener for turning the traction wheel. Operation of the operating element also moves the cutter blade and traction wheel from the inoperative position to the operative position. |
