Abstract: A multipurpose folding hand tool including a tool holder permitting exchanges of blades. The tool may include a folding scissors including a spring that is moved into operative engagement with a scissors handle to open the scissors handles apart from each other only as the scissors approaches an extended, operative position with respect to the handle of the folding hand tool, within which it may be stowed. A resilient grip member is incorporated in one of the handles of the folding multipurpose hand tool. A wire cutter and a crimping tool are located on pliers jaw tangs, between the pliers pivot and the foldable handles of the tool.

Abstract: A cutting board assembly comprises a cutting board; a frame for supporting the cutting board thereon; and a drawer having a length, a width, and a depth defining a containment space for containing food therein, and having measuring increments marked along a length or a width thereof. The drawer is supported by the frame for sliding movement between a retracted position, in which the drawer is substantially retained within the frame and the containment space is substantially covered, and a protracted position, in which the containment space is substantially uncovered. A volume of food retained within the containment space may be measured using the increments marked along the length or the width of the drawer.

Abstract: A trim tool and paint tray system for use in dispensing paint. The system includes a trim tool having a paint applicator to apply paint to a surface to be painted and at least one edge guard to shield adjacent surfaces that are to remain free of paint from the applicator. The system also includes a paint tray having a paint-receiving well and at least one slot free of paint. The paint tray is configured to receive the trim tool such that the paint applicator is received in the paint well to charge the paint applicator with paint and the edge guard is received in the slot so the edge guard remains free of paint.

Abstract: A chemical mechanical polishing pad having an annular polishing track and a concentric center O. The polishing pad includes a polishing layer having a plurality of pad grooves formed therein. The polishing pad is designed for use with a carrier, e.g., a wafer carrier, that includes a polishing ring having a plurality of carrier grooves. Each of the plurality of pad grooves has a carrier-compatible groove shape configured to enhance the transport of a polishing medium beneath the carrier ring on the leading edge of the carrier ring during polishing.
