There is provided a mechanism for use in a can opener comprising a body; rotationally mounting to said body about a first axis, a drive wheel for engaging the rim of the can; rotationally mounting to said body about a second axis and drivably rotatable by said drive wheel, a cutter wheel; eccentrically mounting to said cutter wheel, a cutting knife movable on rotation of the cutter wheel to a cutting position in which the cutter knife forms a nip with the drive wheel such that the cutting knife penetrates through the cylindrical wall of the can to provide a cut therein as the opener orbits relatively therearound, wherein said cutting position is defined by a cutting interval corresponding to a segment of rotation of the cutter wheel in which the cutting knife is sufficiently proximal to the drive wheel to form said nip; and provided to the cutter wheel, intermittent drive means for providing intermittent drive between the drive wheel and the cutter wheel when the cutting knife is in the cutting position such as to maintain the nip in place for a sufficient cutting interval to provide a full orbital cut around the cylindrical wall of the can.
