Abstract
A non-electric explosive device includes a primary body containing cutting material and including a primary charge positioned in the cutting material; an explosive body at a first axial end of the primary body and including explosive material; and a firing head at a second axial end of the primary body, the firing head including a firing pin secured at least partially inside the firing head via securing device, the firing pin comprising an activating end proximate the primary charge and a blunt end protruding from a distal end of the firing head. A force applied to the blunt end of the firing pin causes the firing pin to retract toward the primary charge and break the securing device so that the activating end of the retracting firing pin impacts the primary charge which ignites the explosive material that causes the cutting material in the primary body to travel radially outward.
