Abstract

The tool has a spring for storing energy which can be released abruptly so imparting a very high initial speed to the cutting blade, assuming complete clean and precise cuts. Operation of handle (43) rotates outer ring (32) moving blade (3) to the open position via inner ring (31) and link (37). This also tensions the energy accumulator spring which acts on inner ring (31) as point (B) passes through the extension of a line joining (D) and (A) to close blade (3).
