An example tin snip tool includes a first blade assembly including a first blade and the second blade assembly including a second blade. The example tin snip tool may also include a bolt configured to provide a pivot point that couples the first blade assembly to the second blade assembly and permits at least a portion of the first blade to bypass a portion of the second blade during a cutting operation, and a blade bypass calibrator including a movable adjustor member coupled to the first blade assembly and configured to contact the second blade assembly when the tin snip tool is in a closed position. An extension length of the adjustor member may define a blade bypass angle defined between a first blade tip and a second blade tip when the tin snip tool is in the closed position.

Designs and methods of operation for balitools such as balisongs, butterfly knives, and baliscissors. Two cylindrical locking pins that connect the handles and the tool or blade(s) have semicylindrical protuberances that are trapezoidally arranged. This enables both the use of tapered handles and smooth rotation of the handles with respect to the tool or blade(s) while requiring only a single button assembly to switch between different modes such as pocket mode, in which the handles are locked covering the tool or blade(s); bali mode, in which the tool or blade(s) can swing freely relative to the handles (and, for baliscissors, the scissor blades are locked together); and, for baliscissors, scissors mode, in which each scissors blade is locked to one of the handles.

Hair-cutting shears, comprising a first grip handle (100) and a second grip handle (200) that are hinged to each other, and further comprising a sharp edge (10) and a support table (20), the sharp edge being disposed at the other end of the second grip handle. The support table is disposed at the other end of the first grip handle, the support table is provided thereon with a cutter table (23) made of a gum material; and when abutting, the sharp edge and the support table are side by side and abut on the cutter table.

A terminal cutter includes a tool frame having a first cutting member coupled to an upper handle having a first cutting surface for cutting a terminal from a carrier strip and a second cutting member coupled to a lower handle having a second cutting surface for cutting the terminal from the carrier strip. A terminal strip guide assembly is coupled to the upper handle and/or the lower handle offset from the first and second cutting members. The terminal strip guide assembly includes a strip guide having a slot receiving the carrier strip and having a guide surface adjacent the slot. The guide surface is configured to engage the terminal to locate the terminal relative to the terminal strip guide assembly and to control a depth of the carrier strip received in the slot.

A cutting and snipping device includes a housing having a front, an opposed rear, an open mouth at the front, opposed sides extending from the front to the rear and each formed with longitudinal slots, and a head projecting from the rear, wherein a blade set into the head is exposed between the head and the rear of the housing. The device includes scissor arms, each having a cutting edge at a front end, an opposed rear end, and a grip extending between the front end and the rear end. The scissor arms are mounted within the housing for scissored movement with respect to each other and for reciprocal movement with respect to the housing between a forward position in which the cutting edges are advanced out of the mouth and a retracted position in which the cutting edges are retracted within the mouth.

A cutting implement including a metal substrate and a coating is provided. The coating has zirconium PVD (ZrCRTiNO), which provides protection against corrosion of the metal substrate. In some instances, the zirconium PVD provides protection from corrosion for at least 200 hours. A layer of titanium nitride (TiN) can be added to the coating to increase the hardness of the metal substrate. In such an embodiment, the layer of titanium nitride (TiN) is applied before the zirconium PVD (ZrCRTiNO). Titanium nitride (TiN) coated steel is 3 to 5 times harder than uncoated steel. Thus, a combination of titanium nitride (TiN) and zirconium PVD (ZrCRTiNO) as a coating on a metal substrate can increase the life of the metal substrate by providing increased hardness and anti-corrosive properties.
