Abstract: A tool assembly is arranged for simultaneous treatment of both sides of the edge of a knife. The tool assembly comprises a tool in the form of a stave having faces extending longitudinally between first and second ends of the stave. A holder is provided in which the stave is journaled pivotally within a restricted pivot angle range (?) defined by a pivot limit function accomplished through interaction between the holder and the stave. A pivot journal means, for example, in the form of a pivot pin and a pinhole, is arranged for journaling the stave pivotally about a center axis of the stave.

Abstract: An apparatus for the treatment of cutting edges includes a first and second tools each having treatment surfaces. The treatment surfaces are arranged to define a V-shaped groove for receiving a cutting tool to be sharpened. The tools are driven by a main shaft and are connected to the main shaft via eccentric bodies rotationally fixed on the main shaft, connecting rods attached to the eccentric bodies, and auxiliary shafts connecting the connecting rods to the first and second tools. A power unit is configured to rotate the main shaft, wherein rotation of the main shaft causes the first and second tools to reciprocate up and down relative to the main shaft.

Abstract: A grinding- and polishing tool in combination, comprising a stave which has an edge-treatment side comprising a primary treatment area covering a part of its length, and which in the length direction of the stave is followed by an adjoining secondary treatment area covering another part of the length of the stave. The treatment areas are oriented at intersecting planes such that an intermediate angle between adjoining primary and secondary treatment areas is other than 180°. Also disclosed are a tool assembly, an attachment for a food slicer machine, and a method, all of which are unique implementations of the combined grinding- and polishing tool.

Abstract: A grinding apparatus includes at least two oppositely arranged series of surfaces in slanting relative orientation and alternately overlapping each other, forming this way a groove into which an edge or cutting edge is insertable for polishing by the surfaces. The surfaces of each series of surfaces are arranged in a common plane forming a side in a respective block, the blocks arranged in a holder by which each block is spring biased towards the opposite block, the blocks operated in reciprocating movement transversely to the longitudinal direction of the edge/cutting edge while the surfaces contact opposite sides of the edge/cutting edge under spring action.

Abstract: A device to be detachably mounted on the neck of a bottle in replacement of the bottle's screw cap, and which as mounted provides a reversible closure function by which a flow communication to the interior of the bottle is shifted between open and closing modes, the device including a mounting part (1; 1?; 1?) having an internal thread which engages an external thread formed on the bottle's neck, and a handle (7; 7?; 7?) which is journalled in the mounting part for rotation. The handle carries a head (9; 9?; 9?) which in result of rotation of the handle upwards/outwards from the bottle in a vertical plane provides access to the mouth of a canal (15; 15?; 15?) running through the mounting part, and which head further includes a seal (17; 17?; 36) which, in result of rotation of the handle downwards/inwards towards the bottle, is positioned for closing the canal through the mounting part.
