ABSTRACT:
A two-stage attachment includes two stages of levers arranged to apply a cutting, shearing, squeezing and/or piercing force. The first stage includes a cam lever that has a segmented arcuate pushing surface. The second stage includes a blades support that has an arcuate yielding surface. The pushing surface contacts the yielding surface such that force applied to the cam lever is transmitted to the blade support through the contact between the surfaces.
