Abstract: A gardening shears comprises a first blade (10) and a second blade (20) which are provided with respective hand grips (12, 22), respectively, and are rotatably connected to one another via a pivot connection (13, 23, 30, 41). The pivot connection comprises a pivot bolt (32) passing through respective bores (13, 23) of the first and second blade (10, 20), respectively and secures the blades (10, 20) in axial direction of the pivot bolt (32) to one another. The pivot bolt (32) comprises in its axial direction successive first and second peripheral sections (34, 35), the first peripheral section (34) being rotatably mounted over a limited angular region within the bore (13) of the first blade (10) whereas the second peripheral section being non-rotatably secured within the bore (21) of the second blade.

Abstract: A blade sharpening system for log saw machines is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply a dynamically cushioned pressure between the grinding wheels and the cutting blade. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components. The padded grinding wheels decrease fire risk, and the tensioner can be operated remotely, decreasing human injuries common with conventional setup actions near the sharp cutting blade.

The tool receiving member serves to at least partially receive a processing tool. At least one axial tensioning element of the axial tensioning device pulls the processing tool against an associated tool abutment along a direction of a tensioning axis. While the radial clamping device is decoupled therefrom, the radial clamping device clamps the processing tool by at least one radial clamping element in a direction perpendicular to the tensioning axis of the axial tensioning device. A machine tool may also be provided with the tool retention device.

Abstract: A cutting tool includes a blade assembly with two retractable, opposing blades in a handle shaped for comfortable gripping. The blades may be closed and stowed by being partially retracted into the handle with a continuous motion of a single hand. The blades may similarly be extended and deployed for use with a continuous motion of a single hand. Each blade is formed with a shearing edge and a lever arm. Each lever arm is formed with a slot for engaging a blade locking tab joined to a cover for the handle. When the blade assembly is retracted into the handle, the shearing edges of the blades remain safely closed when the lever arms are released by a person using the tool. The cutting tool includes a retractable tether for preventing loss or damage to the tool should it be dropped.
