Just when you thought razors couldn't get any more advanced, Gillette brought out Fusion, its first five-blade product. Fusion is more than just a bigger version of Gillette's existing lines though - it features a blade on the reverse for difficult to reach areas and an advanced moisturiser strip for rash-free shaving. In addition, the Power version has an auto shut-off feature. No longer will travellers go on holiday only to find that their razor battery has run down in their bag.
