Abstract
The safety knife comprises a longitudinally slidable knife blade holder spring-loaded in the direction of the knife handle and a holding and guide piece on which the blade holder is engaged. The blade holder and the holding and guide piece on which it is mounted are received slidably and enclosed at least partially by a substantially rectangular-cross sectioned handle sleeve. Side members which are part of the blade holder and which enclose the blade are held on the holding and guide piece under spring tension by a tension spring. They are guided longitudinally slidable by guide ribs which engage in guide grooves in the holding and guide piece. One side member is provide with mounting pins which engage in mounting pin holes in the holding and guide piece for mounting and holding it in place even during blade changing when the other side member is tilted so that the blade is accessible.
