Your cutting system works as a co-operation of the the foil and cutter cutting against each other.

Changing just the foil or cutter on their own would be like sharpening just one side of a pair of scissors!

Keeping the shaver clean and free of hairs will improve the quality of the shave and reduce the chance of irritation.

All shavers come with cleaning brushes to brush off any build-up and washable shavers can be rinsed under a tap.

Those with more delicate skin might like to try using a drop of tea tree oil mixed in with the water as it has natural anti-bacterial qualities.
