A knife assembly includes a handle having a first and second handle portion each extending in spaced relationship with one another between a first and second knife end to define a working gap. A knife blade is pivotably secured to the second knife end and pivotable between a closed and engaged position. A switch button is interconnected to the handle for releasing the knife blade from the closed or engaged positions. A spacer is disposed within the working gap and extends between the first and second handle portions. A vial of tritium is housed within the switch button for allowing tritium produced by the tritium vial to be viewable by a user of the knife assembly.

A hand knife tool has alignment markings configured on its blade to help orientate the cutting edge of the knife tool across a workpiece to make a miter cut. A transverse axis is defined perpendicular to a substantially straight middle section of the cutting edge and bisecting the two faces of the knife blade. Each alignment marking is configured on the knife blade at an angle relative to the transverse axis. Each of the alignment markings visually delineate an alignment line substantially across the knife blade between the cutting edge and the blade back. When one of the alignment markings on the knife tool is aligned to the edge of a workpiece, it places the cutting edge of the knife tool across the workpiece at a substantially congruent angle. Then the knife can be pivoted upon its edge and then make a miter cut.

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.

The present invention provides a utility knife having built in smoothing capabilities, either in the form of a utility knife with a grooved cavity for inserting a removable smoothing element with an abrasive surface, or in the form of a utility knife that has an abrasive surface etched into a portion of the utility knife handle. The invention further provides a smoothing element attachment for retrofitting suitable utility knives.
