An anvil (6) is retained or defined by the body and a blade (11) is located within the blade chamber and moveable therefrom along the guide channel to contact the anvil in order to sever an item located within the cutting aperture, such as umbilicals, cables, hydraulic hoses or anchorings. Prior to actuation the blade is located wholly within the blade chamber (12) and encased in a protective material (14) that is retained within the blade chamber by a seal (15) which is broken or cut by the blade on actuation. The seal is preferably comprised of a resilient material that is preferably located within the blade chamber and retained in position by a tube (17) that surrounds the blade.
