A cutter system for an electric shaver and/or trimmer, having a pair of cooperating cutting elements with two rows of comb-like cutting teeth at opposite edges thereof and at least one field of cutting perforations between the rows of comb-like cutting teeth. The cutting elements are movably supported relative to each other by a support structure with an inner one of the cutting elements being sandwiched between an outer one the cutting element and the support structure. The support structure includes a pair of outer frame portions and a pair of inner frame portions supporting the inner cutting element. The inner frame portions form rigid support ribs extending from a base portion of the support structure at a steeper angle than the outer frame portions and forming rigid support edges supporting the inner cutting element along the outer edge of the field of cutting perforations.
