1. A handheld apparatus for cutting a corner post of a palletized unit, said handheld apparatus comprising:
a support plate;
an L-shaped blade disposed between the support plate and a blade cover, said L-shaped blade utilized for cutting said corner post, wherein said handheld apparatus receives said corner post through an L-shaped opening disposed between an L-shaped guide and the L-shaped blade while the apparatus is lowered onto the top surface of the palletized unit;
said L-shaped guide depending perpendicularly from a bottom surface of said handheld apparatus, wherein said guide includes a notch for mating said guide with said blade after said blade has been actuated;
said blade cover, wherein said blade cover covers said L-shaped blade, wherein said blade cover is attached to a bottom surface of said support plate for protecting an operator and the blade;
a piston coupled to said blade for actuating said blade;
a cylinder, said cylinder for receiving said piston when said piston is not actuating said blade;
a trigger switch coupled to said piston, said piston causing said blade to actuate when said trigger switch is depressed, and wherein said trigger switch is coupled to a handle of said handheld apparatus;
a second switch coupled to the bottom surface of said support plate, wherein said blade is actuated only when said second switch and said trigger switch are depressed simultaneously and when said second switch is pressed against said top surface of said palletized unit; and
said blade being disposed below the L-shaped opening, wherein said blade moves parallel to the opening and perpendicular to the corner post, wherein the corner post is formed of paper and said corner post is L-shaped.
