Abstract: A cold knife (10) has a handle (12) within which a receiver bore (34) extends longitudinally. A split collet (38) is slidably mounted within the bore (34) and is configured to receive within a shank groove (40), at any desired longitudinal position therein, the shank (14a) of a cutting blade (14). Because the shank (14a) may thus be selectively positioned relative to split collet (38), cutting blade (14) may be positioned in infinitesimally small increments at a desired degree of extension relative to the cold knife (10). Terminal end (14c) of cutting blade (14) may thus be positioned anywhere from and between extreme positions (P1 and P3) when shank (14a) is clamped within split collet (38) by locking lever (22) moving split collet (38) to place the nose portion (38c) thereof into compressed engagement with reduced-diameter stop portion (34c) of the receiver bore (34).

Abstract: A hand tool made up of a handle member and a tool clamp member where the handle member is made to receive the tool clamp member by engaging a flat surfaced extension of the tool clamp member with a mating hole in the handle member. The flat surfaced extension is tapered in shape and matches with a tapered hole in the handle providing a rigid fit when the handle member and tool clamp member are pressed together. The rigid fit of the two pieces is achieved by elastic properties of the handle member against the externally tapered flat surfaced extension of the tool clamp. The tool clamp provides means to uses replaceable blades or other tools to maintain the tool in good working condition while in use.

Abstract: A double-edged utility knife for carpet installers, roofers, glaziers and sheet rock workers has a two-part handle. The handle clamps a detachable reversible double-edged blade at a transverse angulated position with respect thereto. Vertical cuts can be made in tight corners without applying excessive force.

Abstract: A bipolar electrosurgical instrument has opposable seal surfaces on its jaws for grasping and sealing vessels and vascular tissue. Inner and outer instrument members allow arcuate motion of the seal surfaces. An open lockbox provides a pivot with lateral support to maintain alignment of the lateral surfaces. Ratchets on the instrument members hold a constant closure force on the tissue during the seal process. A shank portion on each member is tuned to provide an appropriate spring force to hold the seal surfaces together. During surgery, the instrument can be used to grasp and clamp vascular tissue and apply bipolar electrosurgical current through the clamped tissue. In one embodiment, the seal surfaces are partially insulated to prevent a short circuit when the instrument jaws are closed together. In another embodiment, the seal surfaces are removably mounted on the jaws.
