A knife with a pressure indication means with a sensor which is actuated when the cutting edge is forced onto a material, a processing means receiving a signal from said sensor and sending a signal to a notification means indicating the pressure as soon as a predefined condition is met.

The present disclosure provides a cone filler. The cone filler includes a first element and a second element. The first element corresponds to at least one filler tube of the cone filler and made up of a first material selected from a first group of materials. The at least one filler tube facilitates storing of at least one of a plurality of constituents. In addition, the second element corresponds to at least one filler tube coupler and made up of a second material selected from a second group of materials. Further, the at least one filler tube coupler enables the first element to couple with a third element. Furthermore, the third element corresponds to a junction module. The junction module facilitates holding of a constituent passage assembly to enable passage of at least one of the plurality of constituents. Also, the constituent passage assembly including at least one closing plug.

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 multipurpose vehicular emergency tool has a power source and a plurality of electrical outputs sufficient to act as a jump-starter for a vehicle or to charge mobile electronic devices, in addition to powering a light source to act as a flashlight. A plurality of emergency tools are provided, including a seatbelt cutter and a window breaker, in order to facilitate one's safety and survival in an emergency vehicular situation. Additional features include an emergency flasher light, a plurality of reflective bands, a compass, an emergency alarm, and a thermometer.

A hair weave removal tool includes a handle, an elongated member, a magnifier, and a light source. The elongated member extends from an end of the handle. The elongated member includes an extension extending outwardly therefrom and a guide member located laterally adjacent the extension. The magnifier is pivotably coupled to the handle laterally adjacent the elongated member. The light source is coupled to the handle, and is configured to illuminate an area above the extension.

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.

A utility knife with a lockable blade is provided. The blade is selectively extended from a housing with a sliding mechanism. The blade is interconnected to a blade carrier that includes a portion configured to lock the blade in a deployed configuration. The blade carrier includes a deflectable portion that is selectively biased by the release button to unlock the blade from the deployed state. Spring force associated with a biasing member interconnected to the blade carrier draws the blade into the housing when the release button is dispersed.

Multi-tool devices and methods of customizing multi-tool devices in a web-based ordering system are provided. One embodiment of a multi-tool device includes a plurality of compartments, wherein each compartment is configured to house one or more attached tools, one or more removable tools, and/or one or more storage ports. Each compartment includes a moveable portion that is configured to be moveable with respect to the other portions. The multi-tool device further includes at least one pin configured to connect the plurality of compartments together. Each of the moveable portions of the compartments is configured to move between a storage position and a deployed position. When the moveable portions are arranged in their respective storage positions, an outer surface of the multi-tool device has a disk shape, an ellipsoid shape, a truncated ellipsoid shape, a spheroid shape, a truncated spheroid shape, a sphere shape, a truncated sphere shape, an ovoid shape, or a truncated ovoid shape.

A kitchen utensil for analyzing food is provided. The kitchen utensil comprises a blade comprising a first surface and a second surface, a handle, a biosensor attached to the first surface of the blade and configured to detect molecules associated with spoiled or poisoned food produces and to output a detection signal corresponding to the detection of the molecules, an electronic circuitry configured to receive the detection signal from the biosensor and to analyze the detection signal from the biosensor, an indication system configured to receive driving signals from the electronic circuitry, wherein the driving signals depend on the analysis of the detection signal, and a power supply that is connected to at least the biosensor, the electronic circuitry, and the indication system.

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.
