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 tree shear capable of reducing an opening degree of handles thereof, includes a shearing part, a first handle and a second handle. The shearing part includes a first blade and a second blade pivoted with each other. The first handle is connected with a first blade, the second handle has a front section and a rear section sleeved with each other, and the front section is connected with the second blade. A link rod has an end pivoted with the first handle and other end pivoted with the rear section of the second handle. While the two handles are opened, the link rod affects the front section of the second handle to move relative to the rear section of the second handle, so as to adjust a length of the second handle to reduce the opening degree of the two handles.

Loppers include first and second elongated handles that are both directly connected and indirectly connected through a linkage assembly. The first handle has a static blade having a concave shearing edge extending generally transverse from the longitudinal axis of the first handle. The second handle has a curved end portion that curves toward the first handle and is pivotally secured to the static blade. An articulated blade has a convex cutting edge and is rotatably secured to the static blade. A link connects the curved end portion to an end of the articulated blade. Movement of the second handle relative to the first handle pivots the curved end portion about the static blade, thereby moving the cutting edge relative to the shearing edge via the link. The static blade and articulate blade are offset from the handles and extend generally transverse to the longitudinal axis of the first handle.

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.

A tool capable of functioning in a first configuration as one type of cutter or pruner and in a second configuration as another type of cutter or pruner has functions to increase the comfort and efficiency of the cutting process. In some embodiments, a pruning saw assembly may be employed with the cutter mechanism for versatility.

A cutting device includes a jaw with a first jaw member and a second jaw member, a first handle attached to the first jaw member and a second handle rotatably connected to the second jaw member at a second pivot point, a gear including a first set of teeth and a second set of teeth at a first end of the second handle. The second handle is slidably connected to the second jaw member at the second pivot point to allow the second handle and the second set of teeth to move into a disengaged position where the second set of teeth are located at a distance from the first set of teeth. To ensure that the teeth of the gear engage correctly, a slide lock is in an enabling state allowing the second handle and the second set of teeth to slide in a slide direction from the disengaged position to the engaged position only when the first set of teeth and the second set of teeth are aligned into a mutually predetermined position.

Foldable, multipurpose shears can have a pair of shearing blades, each blade having a sharp side and a blunt side. The blades are connected to handles via a hinge, and the handles have one side that is straighter and another side that is more rounded or irregularly shaped. One of the blades includes a backward facing hook on the blade's blunt side. Additionally, the blunt side may have partially sharpened serrations. The blades can fold about the hinge for easier transport and storage and the shears are configured so that the hook does not extend past the handles when folded.

For hand-operated garden shears, in particular tree-pruning shears, with a ratchet mechanism, a ratchet lever may be disposed between a hand lever and a scissor lever and the ratchet lever may engage in different latching positions according to the ratchet mechanism. A rotatable abutment surface may be provided on the hand lever and a mating bearing surface on the lever extension, or vice versa, which, at the end of an initial closing operation with the ratchet lever in a first ratchet position, may allow a continuation of the cutting operation as a direct cut without further use of the ratchet mechanism.

A cutting device for the chipless cutting of a material comprises a cutting part and a supporting part. The cutting part and the supporting part are designed to be rotated with respect to one another about an axis of rotation between an open position and a closed position. A hand lever is articulated to the supporting part for pivoting about a pivot axis. A ratchet mechanism converts a back-and-forth motion of the hand lever into a continuous rotational motion of the cutting part toward the closed position. The ratchet mechanism includes a toothing and a drive pawl, which can be brought into an effective position with respect to the toothing. Furthermore, the cutting device comprises a coupling mechanism, which converts a one-time pivoting motion of the hand lever into a rotational motion of the cutting part. A separate coupling element transmits force from the hand lever to the cutting part.
