A pair of gardening shears include a first driving arm, a jaw member pivotally connected with the first driving arm, a second driving arm pivotally connected with the first driving arm, a first handle mounted on the first driving arm, a second handle mounted on the second driving arm, and a locking unit mounted on the first handle. Thus, the jaw member is pivotally connected with the first driving arm by the first bolt, and the second driving arm is pivotally connected with the first driving arm by the second bolt, so that the jaw member and the second driving arm have different fulcrums to construct a multi-lever structure so as to perform the cutting action smoothly in an energy-saving way.

A hand tool includes a first jaw; a first handle coupled to a second jaw, the second jaw pivotably coupled to the first jaw and having a first geared structure, the first geared structure including a first plurality of teeth and a first bearing surface; and, a second handle coupled to a lever, the lever pivotably coupled to the first jaw and including a second geared structure, the second geared structure including a second plurality of teeth and a second bearing surface, wherein the first and second handles are movable between a full open position and a full close position such that during movement from the full open position to the full close position, the first plurality of teeth are at least partially engaged with the second plurality of teeth and the first and second bearing surfaces are in rolling contact.

A control device of a cutting tool formed by a first component and a second component pivotally connected to each other is pivotally connected to the second component. The control device can be pushed to act on the second component. The cutting tool performs multi-stage or one-time cutting according to the control device being pushed to the required position. Moreover, the first component and the second component are close to or away from each other under control of the control device.

A multi-position lock for a pruner or secateur comprises a movable selector for selection between a locked condition for the blades of the pruner or secateur and one or more degree of opening positions for the blades. A typical example allows locked, maximum half open or maximum fully opened operation of the pruner or secateur.

A cutting tool such as garden shears, secateurs, toppers, scissors, tin snips, cutting pliers, and the like that employs a circular disc with a sharp, beveled edge. During the cutting process, the disc engages with an opposing jaw. Furthermore, in the cutting process, the disc is forced to rotate by a ratchet mechanism or other means. The circular disc can be easily sharpened by mounting it on a rotatable shaft. The beveled edge is then engaged with a sharpening stone or file as the disc rotates. Optionally, the tool can include a built-in, self-sharpening mechanism. Here, an abrasive sharpening element is constantly engaged with the beveled edge of the disc. Thus the disc is continually sharpened as the tool is used, and never needs to be sharpened manually.

A hand operated cutting tool includes a first handle coupled to a first cutting member, the first handle having a first set of projections; and, a second handle coupled to a second cutting member and movably coupled to the first handle, the second handle having a second set of projections. The handles are movable between a full open position and a full closed position, wherein a first region of movement is defined by the first and second sets of projections being at least partly engaged, and wherein a second region of movement is defined by the first and second sets of projections being disengaged.

A hand operated cutting tool includes a first handle coupled to a first cutting member, wherein the first handle has a first set of projections. The hand operated cutting tool also includes a second handle coupled to a second cutting member, wherein the second handle has a second set of projections. The handles are movable between a full open position and a full closed position, wherein during a first region of travel proximate the full open position the first and second gear projections are at least partly engaged, and wherein during a second region of travel proximate the full closed position the first and second gear projections are disengaged.

A pair of pruning shears with multi-stage actions for cutting branches with larger diameters is revealed. The pruning shears include a fixing member, a blunt member, a cutting tool, a crank member, a moveable handle, a first locking member, and a second locking member. The fixing member, the crank member and the cutting tool are pivotally connected. The cutting tool consists of a blade part and a curved teeth part. The first locking member and the second locking member are pivotally connected to the fixing member and the crank member respectively. Each locking member is disposed with a hook part, a first projecting rod, and a second projecting rod. The first projecting rod and the second projecting rod are arranged symmetrically. The first locking member and the second locking member are engaged with different teeth respectively at different stages. Thereby the pruning shears performs cutting at different stages.

A gardening scissor includes a first cutting unit, a second cutting unit, and a control rod. Each of the first and second cutting units has a tool portion, and one end of each of the tool portions has a first handle and a second handle. The first and second cutting units are pivotally connected together through first and second through holes. An axial hole is formed near the first through hole, and one side of the axial hole has a gap to connect with the step-shaped space. An extending wing that is protruding out from the second handle is formed at a rear portion of the tool portion. When the control rod is inserted into the axial hole and connected with a stopping unit, the control rod can be restricted by the stopping unit and cannot be laterally separated from the axial hole.

A gardening shears includes a first blade, a driving arm pivoted to the first blade, a second blade pivoted to the first blade, and a link arm pivotally connected between the driving arm and the second blade. The bottom portion of the second blade has a sliding groove and positioning recesses. A switching device installed inside the driving arm is locatable at a first usage position where an end of the link arm is stationarily engaged with a positioning recess next to the top end of the sliding groove for enabling a direct cutting mode for cutting a small-sized branch, and a second usage position where the end of the link arm is slidable in the sliding groove and selectively engageable with one of the positioning recesses for enabling a stepwise cutting mode for stepwise cutting off a large-sized branch by changing the force-applying fulcrum.
