A knife storage system and method is disclosed. The system and method utilize a resealable tube with retractable end-caps to safely store a hunting knife that may be contaminated with blood residue from a game animal that has been field dressed. The end-caps are configured with grooved cylinders to safely restrain a hunting knife so as to prevent dulling of the knife edge while simultaneously providing a fluid seal to the resealable tube to prevent contamination of the tube exterior with blood or other animal residue. Removal of both end-caps permits the tube and end-caps to be cleaned of game residue. Incorporated within the end-caps are integrated knife sharpening inserts comprised of ceramic and tungsten carbide to allow the knife to be safely sharpened in the field.

A cutter apparatus includes a housing and a blade holder coupled to the housing, wherein the housing includes a distal portion (e.g., a blade storage compartment) that is both slidably and pivotally coupled to portions of the housing and configured to serve as a cover for the blade holder. The cutter apparatus can also include a cover release device configured to facilitate repositioning the cover between a locked position at which the cover is secured to the housing and a released position at which at least a portion of the cover is free to pivotally reposition away from the housing providing access to the blade holder.

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.

Latching tool sheaths have a body defining an elongated sheath, the sheath adapted to receive the blade with the blade oriented in a blade plane, a latch element connected to the body, the latch element being movable between a first retention position and a second release position, an engagement element adapted to engage the retention facility when the latch element is in the retention position to prevent extraction of the knife from the holster, and the engagement element being adapted to disengage the retention facility when the latch element is in the release position to enable extraction of the knife from the holster. The retention facility may be a recess and the engagement element may be a protrusion. The retention facility may define a ledge surface facing away from the blade.

The utility knife assembly includes a housing which extends in a longitudinal direction between opposite ends and presents an at least partially open interior. A blade with a sharp edge is fixed with the housing such that the blade extends through one of the longitudinal ends, and the blade is fixed with the housing in such a manner that it is non-movable relative to the housing. A blade protector is partially disposed in the open interior of the housing and is movable in the longitudinal direction relative to the housing between a retracted position and a covering position. In the retracted position, the sharp edge of the blade outside of the housing is exposed for cutting, and in the covering position, the sharp edge of the blade outside of the housing is covered by the blade protector.

A knife, components thereof, a sheath therefor, and associated methods. The sheath may be releasably retainable on the blade by engagement of connection structure of the sheath and blade formed by inserting the blade into the sheath. The blade may include a bottle opener. The knife may include a finger recess adapted to receive a finger of a user when the knife is gripped by the user. The knife may be an ulu knife.

An article of clothing providing a pocket for safely and securing concealing a self-defense device in an easily accessible location. The article of clothing may be a bra or tank-top having a pocket or sheath made of a cut-resistant material and configured for removably securing a knife or dagger. The pocket may also be configured to removably secure an aerosol canister containing a chemistry configured to deter an attacker, such as pepper spray. In one embodiment, the article of clothing is a bra with a pocket position between the two cups of the bra. The pocket is configured to removably secure a sheath made of a cut-resistant material, wherein the sheath is configured to removably secure a knife or dagger.

Replaceable blade knives have an elongated body having opposed ends, a handle portion extending to a handle end of the elongated body, and a blade attachment facility at an opposed forward end of the elongated body, the blade attachment facility having a blade support surface configured to abut a major face portion of the planar blade proximate the elongated aperture, an elongated boss sized to closely receive the elongated aperture of the planar blade, the elongated boss defining an undercut configured to receive a blade portion at the constriction to prevent separation of the planar blade from the blade support surface when the planar blade is in an installed condition with the elongated boss received in the elongated aperture, and a movable ejector element connected to the elongated body and operable to engage the rear end of the planar blade to eject the planar blade from the holder.
