Abstract: A method for producing a replaceable cutting head is described. The replaceable cutting head is manufactured by extruding a blank. During extrusion of the blank, a number of helical coolant channels and a number of helical flutes are simultaneously formed. After extrusion, the flutes have a first angle of twist (D1), and the coolant channels have a second angle of twist (D2). After extrusion, the blank is sintered and then reworked to selectively adjust the first angle of twist (D1) and the pitch of the flutes. The method produces an endless blank that is capable of being parted off to a desired length without any sacrificial allowance, which provides significant material and cost savings as compared to conventional methods.

Abstract: A nail clipping device with scissor-like cutting edges and a positively engaging pin to trim a nail. In one example, a user interacts with the nail clipper to trim a nail by applying pressure to an operating lever element resulting in the movement of the cutting edges sliding against and past each other to trim a nail in a manner similar to using scissors. In this process, the positively engaging pin applies a longitudinal force to an intermediate lever resulting in an upper cutting edge being urged against a lower cutting edge creating a constant contact point between the cutting edges. This results in a clean and easy cut while containing and controlling the trimmed nails.

Abstract: An apparatus and method for faster pathology are provided that removes the need for time consuming preparation of a hardened tissue block. Such hardening is necessary to enable cutting of the thin tissue sections required for pathology evaluation. Rather the tissue specimen is hardened by freezing only at the surface from which tissue is to be sectioned by contact with a cold surface or slide thereby lessening the time required for hardening. Sectioning is performed by passing a cutting device such as a blade, cutting wire or laser beam along a plane parallel to the cold surface and using the cold surface as a guide.
