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.

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.

In one or more embodiments a system of foldable shears is provided, comprising a pair of shearing blades, each blade having a sharp side and a blunt side. The blades are connected to handles via a hinge, and the handles have one side that is straighter and another side that is more rounded or irregularly shaped. One of the blades includes a backward facing hook on the blade's blunt side. Additionally, the blunt side may have partially sharpened serrations or other features. The blades can fold about the hinge for easier transport and storage and the shears are configured so that the hook does not extend past the handles when folded to prevent catching the hook on anything or damaging any nearby equipment.

A cutting tool is provided which may include a first blade and a second blade, where the first blade is coupled to the second blade at a first pivot point, where the first blade defines a cam follower and pivots relative to the second blade about a first pivot axis through the first pivot point; and a lever pivotably coupled to the second blade at a second pivot point, where the lever defines a cam surface and pivots relative to the second blade about a second pivot axis through the second pivot point, where the second blade is driven toward the first blade in response to the lever being advanced toward the first pivot point and the cam follower translating along the cam surface.

A cutting tool is provided which may include a first blade and a second blade rotatably coupled to the first blade. The cutting tool may include a first handle rotatably coupled to the first blade, the first handle rotatable between a deployed position and a folded position, and a second handle rotatably coupled to the second blade, the second handle rotatable between a deployed position and a folded position. The cutting tool may also include a first rotation lock configured to hold the first handle fixed relative to the first blade. The first handle may be configured to be rotatable relative to the first blade in response to the first rotation lock being disengaged. The first rotation lock may be configured to be held in the disengaged position in response to the first handle being disposed between the deployed position and the folded position.

Foldable, multipurpose shears can have a pair of shearing blades, each blade having a sharp side and a blunt side. The blades are connected to handles via a hinge, and the handles have one side that is straighter and another side that is more rounded or irregularly shaped. One of the blades includes a backward facing hook on the blade's blunt side. Additionally, the blunt side may have partially sharpened serrations. The blades can fold about the hinge for easier transport and storage and the shears are configured so that the hook does not extend past the handles when folded.
