A tubing and casing cutter is shown which can be assembled in the field from a plurality of pressed segmented pellets of free standing explosive material. The segmented pellets have a liner glued to at least one exposed face thereof. The pellets are glued to a backup plate with two mirror image plates being stacked to form a plate assembly. A plurality of plate assemblies are stacked within a surrounding container to form the cutter. The pressed pellets can also be assembled within a cup-shaped container to form a shaped charge.
