  • Patent number: 6763972
    Abstract: A dispenser for thin replaceable knives, for example microtome knives, comprises a housing (3) for the reception of multiple knives (2) arranged in a stack (5). The housing includes a cover (7) and a longitudinal wall (10) adjacent to the housing cover (7) through which a dispensing opening (9) is provided. A spring (6) is arranged for biasing the knife stack (5) against the inside of the housing cover (7), and a slider (8) is provided to travel within a groove (16) on the outside of the housing cover (7) for engaging an individual knife (2) and pivoting the individual knife such that at least a portion of the knife protrudes out of the housing (3), wherein a knife edge (11) along the protruding knife portion faces back in the direction of the opening (9).
