A cutter 10 having a support member 12, a handle member 30 which is movably coupled to the support member 12, and a pair of cutting members 39, 40 which are attached to the handle member 30. The cutter 10 includes a support member 20 which receives a metal stud member 24. The cutting members 39, 40 selectively and cooperatively cut or sever the operatively and stationarily received metal stud member 24 when the handle member 30 is moved to a closed position.

A cutter for cutting a predetermined shaped piece from a material, such as paper, is disclosed. In one embodiment, the cutter comprises a middle, rigid cutter member and an outer, flexible non-cutting jaw member. The jaw member comprises a pair of elongated arms, a first arm and a second arm, which are joined together at a connected end. The cutter further includes an attachment member for attaching the connected end of the non-cutting jaw member to the middle, rigid cutter member.

Around a push button formed on an arm 3, teeth are disposed at a regular angle, and around the push button inserting hole in a handle 4 grooves are disposed corresponding to the teeth, thereby, by biasing the arm 3 with a compressed coil spring to engage the teeth with the grooves. Whereby, by pushing the push button to cause the arm to stroke, the engagement of the teeth and the groove is released to cause the arm 3 to turn and by freeing the push button the teeth and the grooves are engaged, t...

The invention is directed to a cutter comprising, a base plate formed by bonding two sheets of thin ring member together, a plurality of projections formed thinner than the base plate on the peripheral edge thereof, an provided with holes and slits which are interposed therebetween, wires passing through the holes so as to connect the projection, and a ring-shaped cutting body including abrasive grains and formed around the projections so as to expose a portion of slits. Since the projections ar...

A cutter for cutting a thin material by engagement between a movable blade and a fixed blade comprises a spring member which is disposed between the movable blade and a movable base for moving the movable blade in the direction of engagment and is adapted to urge the movable blade in a direction perpendicular to the linearly reciprocal motion of the movable base so as to bring the movable blade into contact with the fixed blade.

A blade assembly for a lawn mower has a generally planar body (1) rotationally balanced about a vertical central shaft (24), with four projecting blades (6) extending radially from the periphery of the planar body. The planar body (1) is shaped with vanes (3) to form a fan-like impeller. The impeller is arranged to create a strong rotational flow, which carries air and cut material around the blade assembly in use. The projecting blades (6) create an updraft in a peripheral region of the blade a...

A cutter can rapidly and safely cut the edge of a variety of paper products and a variety of strings and other materials used for packaging. The cutter has a pair of holders laminated to each other, a pair of open-close bodies which are rotatably supported at edge portions of the holders, respectively and form a cutting area through which a paper product can be passed, and a cutting blade which is mounted to the edge portions of the holders and has a cutting edge protruding into the cutting area...

For dividing a chunk of material which comprises areas tending to deform as well as rigid areas, a cutter with a spiral cutting edge is provided. The cutting edge has two sections of which the first in the direction of rotation, is unserrated and undergoes a relatively rapid increase of radius. The second section in the direction of rotation is serrated and follows a minimal increase of radius. With a cutter thus designed, material can be cut smoothly in the region of its deformable portion and ...

A cutter includes a movable blade, a handle and a slider. The movement of the slider causes the blade to move between an extended cutting position and a retracted storage position. The slider includes one projection which is pressed against a surface of the blade so as to frictionally engage the blade for preventing its free rotation or movement during the cutting operation.

Cutting apparatus including an anvil portion having a slot therethrough, a rotatable knife portion disposed within the anvil, anvil support means swingable from an operating position to a rest position, positioning means for moving the anvil support means into an operating position and knife actuating means for rotating the knife within the anvil when the anvil is in an operating position.
