Detonating cord cutter

The cap crimper tends to pinch the detonating cord, crushing the crystals forming the powdered explosive. This poses a safety hazard in itself. Further, this pinching action also tends to loosen the packed powdered explosive at the newly cut ends. This loose powder is usually lost so that the core explosive tends to be recessed from the end of ...
