SACI is an obsolete minimum-metal Anti-Tank (AT) blast mine that has been manufactured in several variants. The specifications given below are for the SACI 54/7, which was copied by Egypt as the B Mk 1. The mines have a Bakelite casing in the shape of an inverted truncated cone, which is filled with TNT. This is covered by a dished plate in which there are three evenly spaced threaded fuze wells; a variant has different sized threads and an additional central well. Beneath each of the wells is a cylindrical booster with a central cavity to accept a stab-sensitive detonator. Two types of fuzes were made (see diagram), both using strikers retained by circular shear disks encapsulated in thin plastic domes; one type also has a striker spring. The fuzes are covered by a pressure plate, which may either be thin Bakelite with three prominent ribs, or hard rubber with a raised cruciform shape. The mine has 2 auxiliary fuze wells, one in the base and one in the side. A rope carrying handle is attached through lugs near the base and a retaining strap is sometimes present across the pressure plate. The majority of the casing is the brown colour of unpainted Bakelite.
