Abstract

A knife has a blade holder in a housing adapted to hold a blade and shiftable between a first cutting position with the blade projecting a little from the housing and a second position projecting somewhat more from the housing. An actuating element shiftable in the housing between a starting position and an actuating position is effective on a connecting linkage such that in a first orientation force is transmitted to the blade holder to retain the blade holder against moving into its retracted safety position from its first cutting position and in the second orientation the linkage does not prevent the blade holder from moving into its safety position from its second cutting position.
