Abstract: An improved chop saw cutting deck is moveably attached to a chop saw base with a hinge mechanism. The axis of the hinge mechanism is perpendicular to the vertical axis of the chop saw's cutting wheel, thereby allowing a change to the angle of inclination between the cutting wheel and materials placed on the cutting deck. For certain material profiles, this alternate inclination angle presents a smaller material surface area to the cutting wheel, and translates to cooler, faster, and more efficient abrasive cutting action. The cutting deck is supported in its inclined position by a deck support means, and may be reconfigured back to a horizontal orientation for effective cutting of various other material profiles. In addition, the preferred location of the hinge axis provides a consistent, lateral line of elevation across the cutting deck, thereby assuring continuous contact of elongated materials with supplemental material supports, such as sawhorses, throughout the cutting deck's range of motion.

Abstract: A blade clamp, for use with a power tool having a reciprocating spindle, includes a cover rotatably coupled to the spindle and a detent received within a bore of the spindle.

The blade clamp further includes a sleeve in which the detent is slidably received. The sleeve includes a non-corrosive material for inhibiting corrosion of the detent.

Abstract: An objective of the present invention is to provide a grille for a hair shaver. In the present invention, by the combination of V-shaped hair shaving slots (including hair shaving long slots and hair shaving short slots) formed on the support surfaces at preset intervals, while contacting with the skin by the support surfaces, the hair is distributed to the hair shaving long slots and the hair shaving short slots on two sides, so that the hair is easier to enter a hair shaving region without escaping against the support surfaces. Accordingly, without reducing the effective hair shaving area, it is convenient for long hair to enter a hair shaving part, and a larger effective hair shaving length is obtained; and meanwhile, an effective support is provided for the skin, and the skin is prevented from being scratched by a blade.
