Abstract: A cutting blade apparatus includes a blade and a replaceable cutting edge component that is removably engageable with the blade. The cutting blade apparatus may be used in a variety of cutting applications, and in some embodiments may be useful in rotary lawn mower applications. The replaceable cutting edge components may present a profile useful in vegetation mowing and mulching applications. The cutting blade apparatus of the present invention facilitates the maintenance of high-quality cutting edges without the need to disassemble the blade from its mounting.

Abstract: A vegetation cutting apparatus includes a rotatable member having an anchor at a first axis of rotation, and a cutting component that is removably coupled to the anchor. The cutting component may be rotatably coupled to the anchor about a second axis of rotation, and the cutting component may be couplable to, and decouplable from the anchor without tools. In some embodiments, the cutting component is fabricated from a plastic material.

Abstract: A multi-section hollow sound chamber containing a plurality of beads and including bore holes or a tubular mounting bore, which is isolated from the sound chamber, for supporting the chamber from a fishing line, wire-form or lure. Associated buoyancy and rotation means facilitate auditory sounds. In various constructions, the chamber parts mount in mated and bonded relation about a hook shank, a wire-form coupling member or a fishing line. Included fins or external grooves facilitate chamber rotation with movement relative to water.
