Abstract: A quick release utility blade holder preferably includes a handle member and a retention clip. The handle member preferably includes a clip pocket, which is sized to receive the retention clip. A pair of opposed blade grooves are formed below a bottom of the clip pocket to slidably receive a utility knife blade. The retention clip includes a lift tab, a notch lock projection and a blade stop projection. The blade stop projection stops insertion of the utility knife blade. The notch lock projection is sized to be received by one of the notches in the utility knife blade. The lift tab extends from one end of the retention clip at one end of the handle member and one end of the clip pocket. The other end of the retention clip is secured to the handle member at the other end of the clip pocket with at least one fastener.

Abstract: A glass-setting apparatus may include an upper support arm and a lower support arm. The upper support arm may be attachable to a roof of a vehicle and may have a holding mechanism operable to hold a top edge of a sheet of material. The lower support arm may be attachable to a hood of the vehicle and may have one or more notches along a portion of the lower support arm that is operable to receive a bottom edge of the sheet of material.

Abstract: A knife blade having a cutting edge with a first end and a mounting edge opposite the cutting edge. Typically the first end will be a point, but other configurations are possible. In addition, the knife blade has a first attachment slot extending from the mounting edge toward the cutting edge and away from the first end. The first attachment slot may be tapered at a select taper angle. In addition, the first attachment slot may include a first segment extending from the mounting edge toward the cutting edge and a second segment extending from the first segment away from the first end. Similarly, a third segment of the first attachment slot may extend from the first segment toward the first end. In one embodiment, the first, second, and third segments form a substantially “T” shaped attachment slot. Preferably, the second and third segments of a “T” shaped attachment slot are tapered at a select taper angle from the junction with the first segment.
