✦ Synopsis

To meet the needs of safety and rescue workers, the portable and convertible SK.7 and SK.5 multipurpose tools have been developed. They can be used in turn as a spade, pick and hoe, and then with the blade of the spade withdrawn, as a pick, axe and shear (model SK.5) together with nail pliers and a bottle-opener (model SK.7). The tool is all-metal, with the various parts in grades of high strength steel The two models are low in weight and compact: SK.7: weight 1.250 kg, length folded 48 cm, length extended 62 cm; SK.5 : weight 2"600 kg, length folded 73 cm, length extended 90 cm.
