A one-hand operable telescopable knife assembly comprising an elongated outermost jacket enclosing an internal emission or containment chamber and an elongated knife blade assembly. A thumb stud is attached to and extends radially outwardly from the elongated knife blade assembly. The thumb stud extends slidingly through an elongated guide slot to permit a first locking notch to a second locking notch movement and control of the knife assembly contained within the outermost jacket. The first locking slot and the second locking slot are arranged at opposite ends of but are also arranged on the same side of the elongated guide slot. A transversely arranged slot on the blade assembly simultaneously lockingly engages a jacket locking tab at the second end of the outermost jacket upon rotation of the blade assembly by the thumb stud entering into the second locking slot on the side of the outermost jacket.

A utility tool comprising a body having a first end and a second end positioned on opposite ends of the body; a removable device; as well as a first tool and a second tool configured to be selectively coupled to each other or one of either the first end and second end of the body. The utility tool includes a removable blade cartridge having a blade cartridge body having a recess slot and a knife slot, a knife blade and a guide. The knife blade is positionable within the recess slot and slides between an open position and a closed position.

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, 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 are also described herein that improve safety of the charging system.

A hand-held tool has two tool parts which are arranged so as to cross one another in a joint region, each tool part forming a working region on one side of the joint region and a grip region on the other side. Each grip region is arranged in a first or second grip sleeve and the first and/or second grip sleeve is provided with a functional part. The first and/or second grip sleeve includes a passage opening extending in a longitudinal direction of the first and/or second grip sleeve and forming a first and/or second opening having a free opening cross-section. The functional part can be inserted into the passage opening in order to mount it on the first and/or second grip sleeve. The first and/or second opening is of substantially elongate rectangular design with respect to a cross-section transverse to a passage direction of the passage opening.

A bracelet or flexible band comprised of a flexible member that on one end is interconnected to a knife and on another end, is connected to a sheath that selectively receives the knife in the locking fashion. When needed, the knife is rotated within the sheath to facilitate release thereof from a lock that is integral with the sheath. Once removed from the sheath, the knife can be used for self-defense, cutting rope or cord in an emergency situation, or for general utility cutting tasks.

Systems, methods, and computer-readable media are disclosed for dynamic nutrition tracking with utensils. Example methods may include receiving an image of a first food item positioned at a first location and a second food item positioned at a second location, the image comprising location metadata, determining, based at least in part on the image and the location metadata, a first set of coordinates corresponding to a first perimeter of the first location of the first food item, and determining a second set of coordinates corresponding to a second perimeter of the second location of the second food item. Example methods may include determining that a utensil performed a gesture associated with a food consumption event, determining that an origination point of the food consumption utensil at a start of the gesture was within the first perimeter, and identifying a weight measurement of a food portion on the utensil.

A multipurpose hand held tool includes a handle and one or more tools. The multipurpose tool may include an inletted recess defined in the handle, and an accessory tool retained within the inletted recess. The multipurpose tool also may include a rotatable tool and a locking mechanism for locking the rotatable tool in multiple positions. The multipurpose tool further may include a compact spanner wrench rotatably connected to the handle. The multipurpose tool may include a knife assembly detachably connected to the handle. The multipurpose tool also may include a ratcheting bit driver located within the handle. The multipurpose tool further may include a multi-layered plier head. The multipurpose may include a hybrid bearing system. The multipurpose tool also may include a flashlight detachably coupled to the handle. In this manner, the multipurpose tool may incorporate multiple tools and accessories for completing various tasks.

Provided are multifunctional tools functioning as a cigarette lighter socket adapter, safety hammer and cutter used in a car. The multifunctional tool comprises a body portion, a striking mechanism, means for adapting the electricity from the cigarette lighter socket, and blades disposed in a inner surface of the a hook-shaped structure. The tool can be used as an electricity adapter converting the electricity from the cigarette lighter socket into various outlet ports, such as USB ports or any other types of outlet ports or connectors for electronic devices. The striking mechanism enables the striking member in the tool to be shoot out with a high impact force, breaking objects such as a car window. The blade is used to cut objects such as a seat belt when the user is trapped in a car in an emergency.
