Shaver replacement parts - bring back 100% performanceDid you know that a man shaves the area of a football pitch in just 18 months? Braun shavers are very reliable. Nevertheless, the cutting parts – the foil and cutting block – wear down over time with repeated use. This is hardly surprising, as in 18 months you have already shaved an area the size of a football pitch! As a result, Braun recommends you replace the foil and cutting block every 18 months to ensure your shaver continues to perform at its best.
