A shaving apparatus includes an outer cutter ( 60 ), for example in the form of a perforated foil, and an undercutter assembly ( 10 ), adjacent to the outer cutter, which is drivable for linear reciprocation in a reciprocation direction. The undercutter assembly has a driven primary undercutter ( 20 ) and a secondary undercutter ( 30 ), which is moveable with respect thereto, the blade elements of the primary and secondary undercutters being mutually interleaved. When the primary undercutter ( 20 ) is reciprocated relative the outer cutter ( 60 ), the secondary undercutter ( 30 ) also performs a reciprocating movement, which lags behind that of the primary undercutter, so the blade elements of the primary and second undercutters move towards one another at intervals and can trap hairs therebetween, causing them to be pulled in addition to the cutting action and thus achieving a closer shave.
