A rotary cutter comprises a body having a handle and a cutter opening. A reservoir of rotary blades is disposed in the body. A member is moveable between a protective and an exposed operative position. A releasable blade receiver assembly allows a blade to be ejected from the cutter and a replacement blade to be loaded onto the cutter for subsequent usage.

A food slicer, which may be used for cutting a pizza with a single blade, and other food, such as pancakes, with multiple blades includes a housing configured to be gripped by a user in a first tilted orientation in which only the first rotating blade touches a work surface, and in a second level orientation, in which all three blades touch the work surface. A first rotating blade is mounted in the housing offset along a longitudinal axis from second and third rotating blades, whereby the tripod arrangement enables a steady structure during non-use, and whereby the second and third rotating blades may be lifted off of the working surface, while the first rotating blade cuts the pizza.

An electric utility knife having a blade which can facilitate manual precision cutting, at a singular consistent speed or varying speeds, without requiring the user to exert extreme or substantial manual pressure to cut through a material. The blade can be configured as a vibrating/oscillating/rotating blade to perform a majority of the cutting tasks. The user may simply guide the blade and exert minimal manual pressure on the knife. This can reduce the potential for injury and other repetitive motion stress injuries to a user. This can also facilitate greater cutting precision and can reduce cutting time.

A handheld rotary cutting blade includes a toroidal cutting blade and a handheld handle configured to package a section of the toroidal cutting blade; the toroidal cutting blade is arranged to be annular; another section of the toroidal cutting blade extends beyond the handheld handle; an outer side edge of the toroidal cutting blade is provided with a cutting edge; two rollers configured to respectively press against and support opposite inner sides of the toroidal cutting blade are respectively hinged at two opposite ends of the handheld handle; the two rollers are located at the same side relative to the center of the toroidal cutting blade, and the side is a side which keeps away from the middle of the handheld handle relative to the center; two rollers are respectively arranged at two ends of the handheld handle.

A pizza cutter in the form of a disc having three or more edges, a series of rounded corners, equal in number to the three or more edges, which form the interfaces between adjacent edges, a handle having a proximal end and a distal end, an arm located at the proximal end of the handle, the proximal end and the distal end separated by a guard, and the disc connected to the arm.

A wall repair tool includes a cutter rotatable about a cutter axis and having a cutter body with a cutting surface. The cutter body has a central section and a pair of end sections disposed on opposite sides of the central section. The cutting surface has a first cutting texture in the central section and a second cutting texture different than the first cutting texture in the end sections.

A cutting implement including an annular blade defining a central blade aperture and a circular cutting edge. The annular blade is rotatably mounted in a handle covering a covered arc segment of the blade while allowing an outer arc segment of the blade to protrude from the handle. The device may be held through the use of a palm grip wherein some of the fingers of the user are inserted through the blade aperture and press the handle against the palm of the hand. A mechanism may be provided for selectively restraining the rotation of the blade relative to the handle.

A cutting tool includes a first arm assembly which includes a first jaw member connected to a first handle. A second arm assembly includes a second jaw member connected to a second handle. The first arm assembly and the second arm assembly are rotatably connected to one another so as to rotate relative to one another. The first jaw member has a first outer surface configured to project away from the first jaw member and defines a first boundary. The second jaw member has a second outer surface configured to project away from the second jaw member and defines a second boundary. A cutting blade is positioned between the first and second jaw members and is positioned spaced apart from the first boundary and the second boundary with the first and second arm assemblies positioned in one of an open position or closed position.

A battery (1800) for insertion into a battery compartment (150) of a hand-held work tool (100, 200), wherein the battery (1800) has a weight between 3-7 kg, and comprises a groove (1810) arranged on one side of the battery to mate with a corresponding supporting heel (1710) arranged on a wall of a battery compartment (150). The battery further comprises an upper ridge structure (1820) and a lower ridge structure (1830) arranged on an opposite side of the battery compared to the groove (1810), wherein the ridge structures (1820, 1830) are arranged to mate with corresponding dove-tail grooves (1720, 1730) of the battery compartment (150).

An easy to use power rotary shear is disclosed to facilitate cutting rigid and semi-rigid sheeted materials, such as rigid sheeted materials including the likes of metal roofing, or other rolled or formed sheet metal, sheeted semi-rigid plastics, fiberglass, and the like, as well as a method of making same, and a method of using it. This includes utilizing a portable single handed, weight balanced, smooth cutting power rotary shear. One specific preferred aspect has certain features including a v-shaped relief behind the rotary cutting blades that automatically separates the pieces generated by the cutting operation. Cutting rigid sheeted materials, especially large pieces, is made almost effortless with the inclusion of this motorized power rotary shear that can be operated with one hand, while holding the workpiece with the other hand.
