Abstract: An electric power apparatus includes a main planar body having a circular opening that supports a brushless direct-current (BLDC) motor. The motor includes a stator, a rotor, a motor spindle extending through the circular opening, a first end cap formed on a first side of the stator and mounted on the main planar body; and a second end cap formed on a second side of the stator and secured to the first end cap to form a substantially airtight sealed compartment around the stator and the rotor. The rotor includes a series of openings in a radial wall that generates an airflow circulating through the sealed compartment to transfer heat from the stator to the first end cap and the second end cap.

Abstract: A multi-purpose knife has an arcuate shaped blade and a denticulate cutting surface on a curved portion of the blade. The cutting surface includes a continuous cutting edge and a pair of beveled surfaces associated with each denticle which intersect at the end of the denticle to form a second cutting edge adjacent to the continuous cutting edge. The continuous cutting edge and the cutting edge formed by the beveled surfaces all slant so as to point the denticles in a direction toward the handle.
