A workpiece cutting method basically includes providing a workpiece proximate to a first blade including a first cutting edge. The method further comprises moving a second blade including a second cutting edge in contact with the first blade such that the first and second cutting edges of the first and second blades cooperatively engage to cut the workpiece while maintaining the first and second cutting edges parallel to each other.

A device for cutting an aerial obstacle includes a mounting frame; an anchor point for attachment to a hoist; a cutter mounted to the mounting frame, the cutter having opposing cutting blades for engaging and cutting the obstacle when positioned therebetween; a power supply mounted to the mounting frame, the power supply providing power to the cutter for actuating the cutting blades; and a guiding frame extending from the mounting frame, the guiding frame providing an inner guiding surface for directing the obstacle to a position between the opposing cutting blades of the cutter. The device is usable for cutting aerial obstacles, such as cables, beams and/or branches.

An adjustable miter gauge for use with a table saw includes a miter attachment and an adjustable guide bar coupled to the miter attachment. The miter attachment rests on a working surface of the table saw. The guide bar is received in a slot in the working surface. The guide bar includes a main body, which has first and second surfaces parallel to side walls of the slot, an adjustable body, which has a third surface parallel to the first surface, and a deformable biasing member. The adjustable body is coupled to the main body and slidable between a first position, wherein the second and third edge surfaces are coplanar, and a second position, wherein the second and third edge surfaces are not coplanar. The biasing member is arranged between the main body and the adjustable body and biases the adjustable body toward the second position.

A push-breaking device has: a placement stand; a pressing mechanism; and at least one cutting blade tool. By the cutting blade tool, which moves along a first direction with respect the placement stand, the device pushes and bends, and breaks, a portion of a protruding region, which protrudes outward from the placement stand and the pressing mechanism, of the layered electrode sheet, which is pressed by the pressing mechanism in a second direction. An angle of a blade portion of the cutting blade tool with respect to the second direction is 15-30. An angle of the blade portion with respect to the first direction is an acute angle. A length, in the second direction, of a clearance between the blade portion and an end, at the cutting blade tool side, of the placement stand is 10%-35% of a length of the layered electrode sheet in the first direction.

In an example implementation, a corner shearing device comprises multiple cutting profiles that are simultaneously active to each engage a distinct piece of sheet material.
