A folding knife is provided with a power storage device that can be charged and recharged by a charge component that wirelessly receives power from a remote source. In some embodiments, the folding knife can have a device that consumes energy such as a light, a camera, a microphone, an audio speaker, a display, etc. The power storage device and the charge component can be positioned in a scale of the handle where the substantially planar shapes of the scale, the power storage device, and the charge component are oriented in a common direction. In some embodiments, the cavities, recesses, and channels in the first scale that house these components and linking wires are strategically positioned to leave a reinforcing area that provides strength and stiffness to the handle. Various features also described improve safety of the charging system and provide connectivity with external computing systems and electronic devices.

An out-the-front knife comprises a handle having a blade channel, a slider channel, and an insert channel interposed between them. A blade in the blade channel and a firing mechanism in the slider channel configured to extend and retract the blade. The blade comprising a blade insert configured to contact the firing mechanism. The firing mechanism comprises a front slider arm, a rear slider arm, a front lock, and a rear lock. When the blade is in the open position, the blade insert is biased against the front slider arm and the front lock and when the blade is in the closed position, the blade insert is biased against the rear slider arm and the rear lock.

The present disclosure provides a multifunctional tool kit. The multifunctional tool kit knit includes a connecting piece, a cover, a tool, a first shank, and a second shank. The cover is connected to an upper end of the connecting piece. The first shank and the second shank are connected to a lower end of the connecting piece. The tool is inserted into a second hole to reach the bottom of a pin hole. By rotating the cover, the tool is locked on the connecting piece. The first shank and the second shank are movably connected to the connecting piece, and are reversely rotatable by 180 degrees to engage with each other define a handle. The present disclosure achieves effects of saving space and resources, and implementing multiple integrated functions with one tool.

A utility knife and methods for using the same are disclosed. The utility knife includes a handle portion, a head unit attached to the handle portion, and a blade attached to the head unit. The handle portion is made of two parts jointed together by a hinged connection arrangement. A blade support component is also included which orients the blade in perpendicular relation to a central axis of the handle. The exemplary utility knife can safely be used in many applications with a design configured to help prevent user contact with the blade's cutting edge or edges.

A folding knife and related method include actuating elements for locking or unlocking the blade of the knife. The actuating elements are permanently illuminated or backlit so that the actuating elements are more clearly visible in low light conditions and can therefore be safely operated. Such features for knife applications may provide advantages for particular activities where knives are commonly used, such as for law enforcement and hunting.

A cutter apparatus includes a housing with a blade carrier configured for holding a blade, and a handle coupled to the housing via an engagement interface configured to allow a user of the cutter apparatus to selectively interfit together the housing and the handle in multiple different cutter apparatus configurations, wherein the engagement interface includes a coupler configured to permit the housing and the handle to be repositioned further apart in a housing/handle reconfiguring mode in which the coupler permits the handle to be rotatably repositioned in relation to the housing or vice versa while substantially limiting longitudinal movement of the housing relative to the handle.
