ABSTRACT:
A piston, normally contained in a retracted position within a cylinder, is projected by electrical detonation of an explosive charge which is contained within the cylinder between a sealed end thereof and a piston having a circular cutting edge at its end remote from the explosive charge, such remote cutting end being normally held in spaced relation to a wire extending through diametrically opposite openings in the cylinder, by a shock-security pin or equivalent means, of a material of sufficient softness to be readily sheared upon detonation of the charge, allowing the piston to advance into shearing engagement with the wire.
