A cooking knife includes: a handle, a plurality of blades and a sheath. The plurality of blades is disposed on the first portion and the second portion of the handle. The sheath includes two sheath shells and a pivot shaft, the two sheath shells being pivotally connected to each other by the pivot shaft in such a manner that the two sheath shells pivotally rotate by the pivot shaft in reverse direction to get close to each other or draw away from each other.

Contemplated tool and tool cartridge assemblies are provided that include at least one tool component and a movable cover. The movable cover has at least one guard portion that moves to cover or expose at least one tool component to protect a user from injury. Contemplated movable covers could be biased to cover tool components, and can be moved by a user or work piece as needed.

In some embodiments, a blade sheath device may include an elongated body having a mouth and a terminus. A central depression may be disposed on a first side of the body and may extend between the mouth and terminus. A perimeter lip may extend around portions of the central depression. An optional handle guard may be positioned proximate to the mouth, and may extend away from the mouth. A retaining cover, which may be coupled to the perimeter lip, may extend over portions of the central depression. One or more magnet elements may be coupled to the body proximate to the central depression. A securement fastener may be coupled to the device on a second side of the body. Optionally, the device may comprise one or more apertures which extend through and between the opposing sides of the device, such as through the body and/or through a handle guard.

A container holds spreadable food and a handheld spreader. A sheath is configured on an inside surface of the container comprising a top sheath opening at a top of the sheath sized to receive the handheld spreader. The top sheath opening is configured with a same size and shape as a cross-section of the handheld spreader to scrape and clean the handheld spreader when the handheld spreader is slid in the sheath. The sheath has sheath opening near a bottom of the sheath configured to permit flow of liquid therethrough when the handheld spreader is slid in the sheath. The handheld spreader can fixedly attach to a central underside of a screw on lid. The handheld spreader can have a handle area on an end and a spreading surface on an opposing end. The sheath can be integrally formed of the same material as the container.

According to one embodiment, the stacked body includes a plurality of stacked units and a first intermediate layer. Each of the stacked units includes a plurality of electrode layers and a plurality of insulating layers. Each of the insulating layers is provided between the electrode layers. The first intermediate layer is provided between the stacked units. The first intermediate layer is made of a material different from the electrode layers and the insulating layers. The plurality of columnar portions includes a channel body extending in a stacking direction of the stacked body to pierce the stacked body, and a charge storage film provided between the channel body and the electrode layers.

A sheath for a knife includes a main body that includes a top face, a front face and a pair of side faces. The front face is wider than the side faces. The sheath includes a cavity that is defined by the main body. The cavity includes an opening in the top face and is configured to receive at least a portion of the knife. The sheath includes a latch that is disposed in the main body. The latch is spring loaded and has a projection as least partially positionable within the cavity.

A cutting device is disclosed. The cutting device has a housing and a carriage that is movably disposed in the housing, the carriage being movable between a retracted position and an extended position. The cutting device also has a cutting member that is removably disposable in the carriage, a cover member that is removably attachable to the housing, and an urging member that operably connects the carriage and the housing. The housing includes a locking member. When the carriage is in the extended position and the cover member is attached to the housing, the locking member locks the cover member to the housing. The urging member urges the carriage to move from the extended position toward the retracted position.

When the carriage is in the extended position and the cover member is attached to the housing, the locking member locks the cover member to the housing. When the cutting member is disposed in the carriage in the extended position, the cutting member is retained in the housing by the locked cover member.

A self-defense tool having a blade that is designed primarily for self-defense is described. The design is intended to eliminate intent to kill on the part of the user when used in defense of an attack. The tool cannot easily be used as an offensive weapon. Thus, when used properly, the tool is geared to take the intent to kill away from the user. The tool is designed to hit the pressure points or places of an attacker and give time for the user to make a critical decision to run or defend. The sharpened blade portion has a reverse cut that is intended to cut more as an attacker pulls away than when the sharpened blade portion is thrust forward. The design minimizes the probability of self-injury by the tool, while maximizing the ability to defend the user from the attacker.

Apparatuses, systems, and methods in which a utility knife includes a blade cover that is movable from a locked position to an unlocked position relative to at least one of a blade cartridge, a blade holder, and a tool handle are provided. When the blade cover is in an unlocked position, the blade cover can advantageously be moved from a blade covering configuration to a blade exposing configuration.
