Abstract: An improved hole punch, wherein a gap is formed between a base plate located at a lower portion and a main body, which is provided with a pivot shaft pivotal configured with a pressure plate. A through hole is defined in the main body beneath the pressure plate, and a press key is located above the through hole. A punching pin mounted with a spring is disposed beneath the press key. An adjusting plate is symmetrically pivoted on two sides of the gap, and an adjusting bar penetrates the rear end of the main body. Accordingly, rotatably adjusting the two adjusting plates to the corner angle of paper enables perforating the paper corner placed within the gap, moreover, the front end position of the adjusting bar can be adjusted to enable the paper edge to be retained thereat and enable punching holes at a consistent distance from the paper edge.

Abstract: A shape cutting system for cutting a material having a surface. The shape cutting system includes a cutting unit and at least one template. The cutting unit includes a frame, a blade adjustment assembly and a blade assembly are coupled to the frame. The blade assembly is positioned at least partially within the frame such that a longitudinal axis of the blade assembly is substantially perpendicular to a lower support surface of the frame. The blade assembly includes a blade retainer and a blade connected to the retainer. A rigid collar of the retainer is configured to operatively engage at least one of a periphery and the edge of an opening of the template thereby enabling the blade to cut a shape in the cutting material which assimilates the shape of at least a portion of the at least one of the periphery and the edge.

Abstract: A band saw attachment for working in conjunction with a band saw for cutting arcuate panels from a piece of stock. The attachment includes a frame structure and a carriage movably mounted on the frame structure and movable back and forth between selected cutting positions. A rotating support is pivotally mounted to the carriage and pivotally movable back and forth relative to the blade of the band saw. In operation, the rotating support receives and holds a piece of stock and by rotating the support the blade of the band saw functions to cut arcuate shaped panels from the piece of stock.
