Abstract: A razor treatment system includes a razor having a head, and a razor treatment device including a drum rotationally supported within the razor treatment device, at least two cam members supported within the razor treatment device, at least two guide members configured to cooperate with the cam members to expose the blade, and a first actuating member configured to effect rotation of the drum. The head includes a cover for housing a blade. The cover is configured to expose the blade. The razor interfaces with the razor treatment device to move the cover of the razor to expose the blade. Each cam member may define a cam track that guides linear retraction of the blade, rotational movement of the blade and cover, and linear extension of the blade into a position between the drums.

Abstract: A disc saw blade includes a saw chain mounted around the circumference of a circular disk, which saw chain is provided with driving links, connecting links and cutting links. Due to the driving links, the chain is guided in at least one chain groove arranged around the periphery of the disk. The bottom of the groove has radial projections distributed around the circumference, and the driving link has a cam surface on a projecting part that projects radially inwards, for interaction with the respective radial projection. The chain can move from a neutral position, in which the respective projecting part is loosely disposed between two adjacent radial projections, to a working position, in which the respective cam surfaces are in contact with the associated radial projections.

Abstract: A foldable lighter that prevents inadvertent ignition by erroneously pressing on the operating button at time of folding the swing-arm to make the lighter compact. A foldable lighter 1 that comprises a lighter lighter body 2 that contains a fuel tank, a piezoelectric unit 102 and an operating button 8, and swing-arm 4 connected with free swinging to one end of lighter body 2 and that incorporates a locking mechanism that prevents accidental depression of the operating button 8. The locking mechanism consists of a projecting portions 74 formed in a predetermined range of the cylindrical walls 26a, 26c made integrally with a swing-arm 4 and a hook 8b that extends from the operating button along a portion of the cylindrical walls.

Abstract: A safety razor comprises a handle, a blade element movable relative to the handle in a direction which substantially corresponds to the direction of a working stroke, and an elastic element located between the handle and the blade element as considered in this direction.
