Cutting tools for sample preparation

A cutting tool for cutting, handling and then ejecting disks of material cut from a sheet or like material, the tool comprising:

• a body having a proximal end adapted to be rotatably driven about an axis, and having a distal end including a generally cylindrical cutting portion rotatable about said axis for cutting and receiving said disks;
• an ejector slideable axially parallel with respect to the axis and within said cylindrical cutting portion for ejecting the received cut disks, wherein an ejection tip of the ejector is a flat surface;
• a grip rotatably mounted to the body such that the grip can be held without substantial rotation whilst the body is rotated, said grip being operable to cause said sliding of the ejector and for ejecting the disks;
• wherein the body includes a cavity having an opening, and the ejector includes a portion within the cavity which extends away from the axis and through the opening and can slide therein, said portion providing force transmitting communication between the ejector and the grip;
• and
• wherein a resilient element is included in the cavity providing a force to urge the ejector toward the proximal end of the body.
