ABSTRACT:
A poultry processing device having a pair of substantially flat cooperating side-by-side thin blade-mounting members with a pair of cooperating blades mounted upon and extending forwardly in angled relation from the forward portions thereof, and secured at their rear portions by a transverse pivot pin. An adjustable spring member encircles the pivot pin and has opposite end portions each secured to a different one of the mounting members to urge the blades toward open position. A shiftable pin connects one end of the spring to one of the mounting members and shifts between a variety of positions along the length of one end portion of the spring to vary its torque. The lower blade extends downwardly at about a 45.degree. angle and is longer than the upper blade to compensate for the slicing action of the upper blade which results from the location of the pivot pin. The two mounting members pivot in side-by-side relation within the palm of the hand and a pair of spacer posts extend between the rear portions of the mounting members rearwardly of the pivot pin, one above and one below, which brings the two blades into slightly angled relation. The pivot pin is above and to the rear of the finger grips on the mounting member for the lower blade. The side-by-side assembly of the thin flat mounting members provides a hand-opening and closing action which greatly alleviates stress on the part of the user, as compared to the use of conventional scissors, and greatly minimizes the carpal tunnel syndrome problem currently experienced by so many poultry processors. A thumb rest is carried by the mounting member for the upper blade above and to the right side of that blade so that movement of the thumb is in a plane parallel and immediately adjacent to the palm of the hand of the user rather than at a sharp angle thereto, as is the case in the use of scissors for the same purpose.
