An assembly and method of forming a press cutting die that includes a cutting blade that is supported by a blade support assembly or blade support. The blade support includes a first base portion and a second base portion that are each contoured to cooperate with one another to capture a portion of the cutting blade along an interface between the first and second base portions. Preferably, one or more keys extend between the first and second base portions and traverse the geometric plane associated with the cutting blade. Such a press cutting die is particularly applicable for cutting biologically compatible materials having a desired shape from a bulk source of the biologically compatible material.

A system for generating rules inserted into at least one pattern board including: a controller configured to generate at least one shape diagram, the controller also configured to determine number and measurement of crease rules to be generated based on the at least one shape diagram; a cutting station configured to receive and cut a first crease rule into the number and measurement of the crease rules; and a sorter configured to receive the crease rules from the cutting station and sort the crease rules according to the measurement of the crease rules, wherein the sorted crease rules are inserted into each of the at least one pattern board along with a cutting rule shaped by each of at least one bender.

An exemplary hand-held, power operated rotary knife dermatome comprises a blade housing assembly and a depth gauge assembly. The blade housing assembly includes an annular blade housing and a blade lock ring for rotatably supporting an annular rotary knife blade. The annular blade housing includes a shield extending radially inwardly from a blade receiving body and including an inner wall defining a tissue directing surface, the tissue directing surface including a first tissue guide surface extending upwardly from a lower end of the shield, the first tissue guide surface extending substantially parallel to the blade housing axially extending center line. The blade receiving body includes an annular blade channel extending axially upwardly from a lower surface of the blade receiving body, a bearing surface axially spaced from a lower surface of the blade receiving body, and a threaded portion formed on the outer surface of the annular blade housing.

A stamping tool formed from a steel strip and method of forming the stamping tool. The stamping tool is formed from a steel strip shaped on a narrow side with a cutting part having a cutting edge. The stamping tool includes a back part with a contour in cross section on a narrow side of the steel strip, recesses shaped in the back part with free spreading of the material to be transverse to a longitudinal extension of the steel strip and perpendicular to lateral surfaces of the steel strip, such that an extent of the spreading is smaller than a thickness of the steel strip, and undeformed regions located between the recesses.

A method of treatment of a cutting piece (2) is provided. This method includes a first step in which a cutting surface (5) of this cutting piece (2) is subjected to shots thrown by an ultrasonic shot peening apparatus (10) to become a cutting surface (5) with shot impacts, and a second step in which the cutting surface (5) with shot impacts is grinded over a chosen thickness to become a treated cutting surface (5).

Equipment for treating a cutting piece is provides which includes an ultrasonic shot peening apparatus arranged for throwing shots on a cutting surface of the cutting piece so the cutting surface defines a cutting surface with shot impacts; and a grinding device arranged for grinding the cutting surface with shot impacts over a chosen thickness so that the cutting surface with the shot impacts defines a treated cutting surface.
