A light-weight bolt cutter tool includes a pair of opposing pivotally mounted jaws, each made from a fiber-reinforced composite body jacketed by a blade having a hardened metal outer surface oriented to forcibly engage the other one of said jaws. The bolt cutter tool can be actuated by a pair of elongated, hollow fiber resin composite handles. Each handle can include an elastomeric damping plug to prevent debris entering the hollow handle and reduce material fatigue. A quick-deployment, quiver-style backpack can conveniently carry the colt cutters when not in use.

An in-line portable, hand held hydraulic cutting tool having a handle assembly and a working head assembly is provided. The handle assembly has a tool frame portion and a neck portion. The working head assembly has a pair of jaw members joined so that they are movable relative to each other and held in place by a locking pin. Each jaw member has a cutting blade secured to or directly formed into the jaw member. A stabilizer can be secured to or directly formed into one or both jaw members. The one or more stabilizers are aligned with a respective cutting blade such that during a cutting operation at least an edge of the stabilizer engages an object being cut to limit rotation of the object during the cutting operation.

A hand-held drive cleat cutter-notcher for the cutting and/or notching of sheet materials, particularly drive cleats. The device in one example: a first handle; a second handle pivotably coupled to the first handle at a handle pivot; the handle pivot having a handle pivot axis; an inner jaw coupled to the first handle; the inner jaw comprising an inner jaw cutting edge substantially triangular in cross section in a plane parallel to the handle pivot axis; an outer jaw coupled to the second handle, the outer jaw having an insert surface beveled in a plane orthogonal to a cutting plane orthogonal to the pivot plane and orthogonal to the handle pivot; the outer jaw having a surface defining an outer jaw cutting edge adjacent which the inner jaw cutting edge passes; and wherein rotation of the second handle relative to the first handle rotates the inner jaw relative to the outer cutting jaw.

The present invention discloses a ring cutter and ring cracker intended for use by medical personnel. The ring cutter employs a tissue guard that slips under the ring to protect the patient's finger or other appendage. A clipper head is inserted into the tissue guard. The tissue guard does not move and prevents the jaws of the clipper from injuring the patient. The tissue guard may be constructed of plastic that will break away after use to prevent contamination between patients. The invention also incorporates a ring cracker for breaking tungsten or ceramic rings. A recess in a ring base in one of the arms of the ring clipper retains a part of a ring. In the other arm, a threaded bolt with a hardened tip extends toward the ring. The arms of the clipper can be locked by a bar in a fixed position. A knob on the bolt allows a hardened tip at the end of the bolt to exert pressure on the tungsten or ceramic ring until it cracks, without injury to the patient.

An electric nail gun structure is disclosed. A gun head seat body is formed into a structure with inner and outer cover layers, allowing a rotating rod and a slide piece moving a pull nail linearly to be configured inside it; the gun head seat body is formed completely by having a steel sleeve with equidistantly spaced slide chutes on the inside thereof covered with a plastic contact layer, where the slide chutes allows projecting ribs configured on the steel slide piece to be in engagement therewith so that a stable and safe nail pull operation can be obtained. Furthermore, a length extensible and width adjustable auxiliary handle rod is configured on the outside of the gun head seat body allowing nail gun seat bodies for all kinds of electric, pneumatic drills to be operated conveniently and safely with one single hand.

A crimping hand tool configured to crimp a cable and a housing. The crimping hand tool includes a first body having at least one guiding structure, a second body is pivoted to the first body to rotate with respect to each other to be unfolded and folded, a linking member is pivoted to the second body, and the linking member has a slot, a crimping assembly is pivoted to the linking member and is slidably coupled to the guiding structure, and a shaft is movably inserted in the first body and the slot of the linking member. After the housing and cores are placed into the first body, the second and first body are folded with respect to each other to drive the crimping assembly to move along the guiding structure through the linking member to crimp the housing and the cable together.

In accordance with at least one aspect of this disclosure, a surgical rod cutter assembly includes a first blade member including a first open notch in a first end thereof. The first open notch spans across a first ingress axis, along which a rod is inserted for cutting. A first rotation bore is defined through the first blade member, a linkage of the first blade member extends away from the rotation bore on a first linkage axis, and the first rotation bore intersects the first linkage axis.
