Zusammenfassung:	A circular shaped charge and methods of manufacture, shipping and assembl y. An circular shaped charge is manufactured as two separate charge halves, upp er and lower, and a separate continuous liner or pair of continuous half liners. Preferably, each charge half is formed of a number of segments, each comprising a reduce d weight of explosive which can be shipped under preferred regulations. The explosive contains sufficient binder to prevent damage to the charge segments during shipping and assembly at a job site. The separately shipped components are assembled at the job site to form a complete circular shaped charge useful, for example, in a tubing cutter.
