Abstract: Knives (10, 182) each include a handle (12, 184) having a blade (14, 90, 194) pivotally attached to the handle. The blade is movable between a closed posiiton in which it is received within a groove (36, 192) of the handle and an open position. The blade has a working portion (38, 198) and a tang portion (44, 98, 204), which remains within the groove when the blade is in its open position. A locking pin (72, 208) extends transversely of the handle and blade and is movable along a pair of elongated openings (74, 216), and engages the tang portion (44, 98, 204) of the blade to lock the blade in its open position. A spring (78, 228) biases the locking pin toward the tang.

Abstract: A process for absorbing liquid and solid toxic waste in an agglomerate using asbestos, rock wool and the like as a sponge material. The toxic waste is mixed with the sponge material in a dehydration tank. The dehydration tank is used to remove any residual vapor from the mixed material in order to provide a dry textured mixture. The dry mixture of the sponge material with absorbed toxic waste is than introduced to a resin adhesive mixing tank. The resin adhesive mixing tank is used for coating the exterior surface of the sponge material to prevent seepage and migration of the toxic waste from the sponge material. The coated sponge material with toxic waste is removed from the resin adhesive mixing tank and individual portions of the coated mixture are compacted under high pressure into a stackable solid waste cubes.
