A device for sharpening bladed tools comprising a body defining an elongate handle portion adapted to be gripped in one hand by a user, the body having a forwardly projecting support member curved or angled downwardly with respect to the handle portion and fitted with a sharpening element at or near the end thereof, wherein the support member comprises a pair of spaced support arms extending generally parallel to the longitudinal extent of the handle portion, the support arms being positioned to respective sides of the sharpening element and defining an aperture therebetween adapted to accommodate a blade or anvil of a tool during sharpening of a counterpart tool blade.

A sharpening sheath, designed to receive a knife to be sharpened or stored, comprising a cavity for receiving a blade, an access opening at one end of the cavity, the sheath comprising, preferably in the vicinity of the access opening, an upper part equipped with a device for guiding the back of the blade and a lower part comprising a sharpening device onto which the cutting edge of the blade is intended to be applied when inserting the blade in the sheath or removing it therefrom, characterized in that the sharpening device is supported by an arm comprising a first longitudinal end rotatably mounted on a stand, the arm being returned by recoil means in the direction of the guiding device, and in that the sharpening device is rotatably mounted at a second longitudinal end of the arm.

A device for grinding and/or polishing a cutting edge of a cutting tool. The device includes a handle, at least one roller rotatable relative to the handle, and at least one disc that is rotatable relative to the handle for grinding and/or polishing the cutting edge of the cutting tool. The device can be moved over a substrate by exerting force on the handle so that the roller, which is rotating relative to the handle, rolls on the substrate and the disc can be set in rotation. The disc may be rotatable at a different rotational speed/angular velocity to the roller.

A sharpening sheath, adapted to receive a knife to be sharpened or stored, comprising a cavity for receiving a blade, an access opening at one end of the cavity, the sheath comprising, preferably in the vicinity of the access opening an upper part provided with a guiding device for the back of the blade and a lower part comprising a sharpening device on which the cutting edge of the blade is intended to be applied when inserting or extracting the blade in the sheath, characterized in that the guide device comprises a V-shaped groove and in that the sharpening device comprises two sharpening elements arranged in a V-shape opposite the groove of the guide device, the sharpening device being mounted so as to be movable relative to the guide device and being returned by return means in the direction of the guide device.
