Abstract

The invention relates to a knife including a housing (11) inside which a blade holder (15) is movably mounted. The blade holder (15) comprises a main part (17) and least one holding part (18) which is movable between a holding position and a in replacement position. In the holding position, a blade (16) can be tightly retained in a replaceable manner in a blade seat between a first holding surface (46) of the main part (17) and a second holding surface (45) of the holding part (18), while in the replacement position, the blade (16) can be removed from the blade seat or a new blade can be mounted in the blade seat. The invention is characterized in that in at least one relative position of the blade holder (15) to the housing (11), the blade holder (15) is biased against a stop (21) by a restoring force, and in that the holding part (18) can be moved into the blade replacement position by having an abutment surface (24) on the stop (21) cooperate with a mating surface (25) on the blade holder (15).
