A folding knife includes a handle and a blade pivotably coupled to a distal portion of the handle. The handle includes first side portion including a first locking portion laterally offset from a first main body and second side portion including a second locking portion laterally offset from a second main body. The first side portion is configured to rotate about the pivot axis between a locking configuration where the first locking portion is disposed between the second main body and second locking portion, an opening in the second locking portion and a recess in the first locking portion are aligned, and a locking button is disposed within the recess and opening, thereby restricting relative movement of the first and second side portions, and a release configuration where the locking button is pushed out of the opening, thereby allowing relative movement of the first and second side portions.

A Balisong knife includes a latch that resists compression of the back end of the handles towards each other under grip pressure by the user, thus increasing the columns strength of the handles when the knife is in a latched open configuration. A crossmember is provided adjacent to the latch pivot, resisting movement of the latch into any position wherein interference between the latch and tip of the blade could occur. Integral, friction reducing surfaces are provided on components of the knife. The knife can be assembled using snap fit pivot pins. The blade includes portions of varying thickness, providing additional thickness in the region of the points for greater strength, while allowing center edges for more effective cutting.

A folding knife including a handle, a pivot axis, and a blade having a cutting edge. The blade is pivotably coupled to the handle such that the blade is pivotable relative to the handle about the pivot axis between a retracted position and an extended position. The cutting edge is exposed in the extended position and a portion of the blade is received within the handle in the retracted position. The folding knife further includes a bearing assembly for facilitating movement of the blade between the retracted position and the extended position. The bearing assembly includes a first bearing recessed within the blade and a second bearing recessed within the handle.

A lockable tool with a sliding scale release is formed with a frame and a tool coupled to the frame with a locking mechanism to lock the tool into an extended or retracted configuration. A release mechanism is attached to a scale on the side of the frame. The scale is coupled to the frame. The tool is constructed such that sliding the scale along a longitudinal axis of the frame automatically unlocks the tool from the extended or retracted configurations. The tool can open and/or close automatically. The tool, such as a knife, can swing open or extend out a front opening in the frame.

A utility knife includes a handle base and a neck connected to the handle base for pivotal movement relative to the handle base between a closed position and an open position. The knife also includes a utility blade holder slidingly carried by the neck for sliding movement relative to the neck between a retracted position and an extended position. A utility blade is carried by the blade holder such that movement of the utility blade holder between its extended and retracted positions moves the utility blade between an exposed position in which a cutting edge of the blade is exposed, and a protected position in which the cutting edge of the blade is protected by the neck.

Folding knife embodiments are disclosed herein comprising a blade operable to pivot relative to a handle, between an open position and a closed position, about a pivot axis extending through a tang portion of the blade having at least one locking recess. The knife can have a locking mechanism comprising a rod that extends along the pivot axis through the tang portion and a locking member coupled to the rod which engages the at least one locking recess of the tang portion when the blade is in at least one of the open position or the closed position. The knife can further comprise a push button coupled to the rod, wherein depression of the push button is configured to eject the locking member from the locking recess in the blade, thereby unlocking the blade.

A folding knife has a handle and a blade with a working end and a tang, the blade being coupled to the handle and pivotable relative to the handle about a fold axis between an open position and a closed position. A toggle is coupled to the handle and pivotable relative to the handle about a toggle axis, the toggle axis being located a radial distance from the fold axis. A free end of the toggle has an open lock face located a radial distance from the toggle axis. A primary lock face on the tang is located on the opposite side of the fold axis from the working end. When the blade is in the open position, the open lock face engages the primary lock face to prevent rotation of the blade toward the closed position.
