Abstract: The utility knife blade is a blade for a utility knife having a slot formed in the blade that is especially useful when scoring drywall. The slot may engage a tape measure adjacent the tape hook so that the cutting edge at the scoring tip of the blade extends below the tape measure hook to engage the sheet of drywall. The slot extends through the cutting edge into the body of the blade at a slight angle relative to normal, preferably about 10°. The blade has a slot at each end so that the blade may be reversed when one end is dulled or broken. The blade has an otherwise standard configuration, typically having a trapezoidal body with a cutting edge extending along the longer parallel edge and a pair of notches in the shorter parallel edge for engaging knife holder retainer pins in the slidable utility knife holder carriage.

Abstract: The spray bottle reservoir system includes a bottle having a neck and a body, the body defining a main chamber for containing fluid. A spray cap is detachably mounted to the neck. A vertical partition is disposed inside the body, separating the main chamber to form a dispensing reservoir. A dip tube extends from the spray cap to the bottom of the dispensing reservoir. The dispensing reservoir may be refilled from the remaining chamber, and due to the relative small volume of the dispensing reservoir and the viscosity of the fluid, the dispensing reservoir permits maximum consumption of the fluid in a wide range of spraying positions.

Abstract: An apparatus for marking and scoring a work object has a first member having a first and second side. A flange is connected to a second side of the first member. A second member has a first edge and a second edge. The second member is connected to extend perpendicularly from the first member. The first edge has a plurality of crenulations extending therealong for receiving an instrument. The flange of the first member is positioned against an edge of a work object and the instrument is positioned between adjacent ones of the plurality of crenulations and against the work object. When the first member is moved along the edge of the work object, the instrument is caused to mark or score the work object along a line parallel to the work object.
