A single or multi-hulled sailing craft has a stub mast,upstanding from the hull. A sail,has a luff edge,secured to a luff boom,and a foot edge,secured to a foot boom,which is connected to the lower end of the luff boom. Part way along the luff boom,a pivotal fitting,connects the luff boom to the stub mast,and a rigid swing boom,is pivotally connected between the foot boom,and the hull or the stub mast. The fitting,can be moved up and down the stub mast,by means of a tilt sheet. The swing boom can be connected to a carriage which moves transversely of the hull. The sail is self-tacking and its position is positively controlled to prevent collision of the sail with the stub mast.

A razor blade assembly, in the form of a complete razor or a shaving unit for mounting on a razor handle, has a blade platform supporting a blade and preferably a twin blade is mounted in a razor head frame for rolling movement between a shaving position in which the blade or each blade is correctly positioned, relative to a guardbar and a top cap 28, for shaving to a retracted position in which the blade or each blade is withdrawn from the shaving position.

Razor blade assembly

This invention concerns a razor blade assembly in which a double edged blade strip 9, which subsequently provides first and second blades 10,16 of a twin bladed assembly, is provided, in an insert moulding operation, with a blade platform 11, end walls 15, a guard bar 14 and a blade spacer 13 moulded on the first blade 10, and a top cap 17, end walls 22, a spacer 18 and rivets 20 moulded on the second blade 16. After cropping of the metal joining the two blades or after folding over one blade on to the other, the rivets 20 are brought into apertures 21 in the first blade 10 and blade platform 11 to locate the two blades with their edges parallel and in staggered mutual relationship. Finally the portions of the rivets 20 projecting through the blade platform 11 are flattened to permanently lock the two parts of the assembly together.

A knife sharpener comprises a scabbard 10 for receiving a knife blade 13. A sharpening device 11 is carried within the scabbard to engage a blade edge 14 within the scabbard 10 and can be moved manually along the scabbard to sharpen the blade edge 14. Thus, sharpening is accomplished while the blade is within the scabbard. A locking device 31 is provided to hold the blade within the scabbard 10. Part 46 of the scabbard 10 may be displaced to allow the sharpening device 11 to be removed for cleaning.

A razor blade assembly, in the form of a razor or shaving unit, comprises a top cap 114, a razor blade 113 fixed relative to the top cap, and a guardbar 115 which is pivotally movable relative to the blade from a shaving position, in which the blade is exposed for shaving, to a protecting position in which the guardbar prevents contact between the cutting edge of blade 113 and a user of the razor. The guardbar can be formed integrally with a platform 112 on which a second blade 123 is secured, or the second blade 123 could be secured to the top cap. In either case the guardbar and platform will pivot between the shaving position and the protecting position, and in latter position both blades will be protected.
