Abstract: An acute angle blade sharpening apparatus and method for sharpening blades is configured to sharpen the edge and bevel of a blade at the specific acute angles between 21° and 23°, or about 22° and 23°. The apparatus has a base member forming multiple elongated depressions oriented at 22° and 23°. Multiple elongated sharpening members are fixedly mounted in the depressions. The blade is oriented perpendicular to the first side of the base member and drawn against the sharpening members, to engage at the desired 22° and 23° sharpening angles. A leveling instrument attaches to the blade to verify the blade is oriented at the desired angles. A leveling instrument cavity stores the leveling instrument and fastener. Springs retain the sharpening members in the cavity of the base member when not in use. A clamp fastens the base member to a mounting surface for enhanced stability.

Abstract: A multifunctional irrigation pliers and method of piercing, cutting, and fitting an irrigation tube with an irrigation pliers. The irrigation pliers enables the forming of a hole in an irrigation tube, the placement of a nozzle or a drip emitter into the formed hole or a terminal opening of the irrigation tube, the cutting of a length of the irrigation tube, and general deforming of sections of the irrigation tube. A first jaw and a second jaw are pivotally attached together at a pivoting joint to allow the jaws to be pivotally displaced toward and away from each other by moving a first handle and a second handle to and away from each other. The inner surfaces of the jaw comprise a blade, a spike, and retaining slots sequentially positioned across the jaws to engage the irrigation tube, the nozzle, and the drip emitter.
