Only three stars because the called function using standard bits NOT exist: It will only fit double-headed, shallow Leatherman bits, because of its greater length. Standart bits disappear into the depths of the hexagon socket, you can not use that. A help tip: a 6mm steel ball insert - if you magnetized beforehand, it does not fall out so easily - then it works but then with the normal bits! An otherwise valid what my predecessors have already written so (price, strength, application, etc.).
