A handle having illuminating features, such as on a utility tool, the handle having a housing made up of a first housing section and a second housing section that mate with each other to define a cavity, the first housing section having a plurality of slots through which an internally positioned set of LEDs can emit. The second housing section may similarly have a plurality of protrusions and a second set of LEDs to transmit light. Translucent diffusers may be positioned between the LEDs and their respective housing sections. The utility tool may have additional tools that are spring-loaded to facilitate opening the tools and maintaining the tools in a closed configuration.

A double spring folding knife includes a handle having a curvilinear groove on an interior surface, and a knife blade. The knife blade has a locking pin that extends away from a first side of the knife blade and is configured to slidingly engage the curvilinear groove. A bow spring is fixed to the handle and is orientated to interact with the locking pin in order to exert a force on the locking pin during a portion of travel along the curvilinear groove. The knife also includes a coil spring having a first end fixed to the handle and a second end fixed to a second side of the knife blade, where the coil spring is configured to exert an opening force on the knife blade after the locking pin has traveled past the bow spring along the curvilinear groove.

A folding knife includes a handle, a blade assembly, a stop member, and a locking arm. The blade assembly is rotatably interconnected with the handle and is moveable between an extended position and a closed position. In the extended position, the locking arm exerts a bias force to wedge a releasable wedge member laterally between the stop member and the blade assembly to inhibit a transition of the folding knife out of the extended position. In the extended position, an unlocking force applied to the locking arm displaces the releasable wedge member from a space between the blade assembly and the stop member to permit the transition of the folding knife out of the extended position.

Provided is a knife, including: blade; a first hilt assembly; a second hilt assembly, the blade being detachably disposed between the first hilt assembly and the second hilt assembly; a connecting portion, disposed on the first hilt assembly; and a handle clip, disposed on the second hilt assembly, wherein a position of the connecting portion is adjustable, such that the connecting portion has a locking position connected to the handle clip and an opening position separated from the handle clip. The knife of the present disclosure solves the problem in the related technology that it is more complicated to disassemble blade of a knife.

A folding knife includes a handle and a blade. The handle includes a first portion and a second portion. The blade is pivotably coupled to the handle and is pivotable relative to the handle about a pivot axis between a closed position and an open position. The first portion of the handle includes one or more dovetail-shaped projections. The second portion of the handle includes one or more dovetail-shaped slots configured to mate with the one or more dovetail-shaped projections of the first portion of the handle, and thereby restrict relative movement between the first portion and the second portion in a direction parallel to the pivot axis of the blade.

A folding knife is provided with an opening mechanism having a traction surface to aid users in rotating the blade from the closed position to the open position and to assist with opening the folding knife. More specifically, the traction surface is located on an outer surface of the tang of the blade and extends outwardly from the handle when the blade is in the closed position.

A handle having illuminating features, such as on a utility tool, the handle having a housing made up of a first housing section and a second housing section that mate with each other to define a cavity, the first housing section having a plurality of slots through which an internally positioned set of LEDs can emit. The second housing section may similarly have a plurality of protrusions and a second set of LEDs to transmit light. Translucent diffusers may be positioned between the LEDs and their respective housing sections. The utility tool may have additional tools that are spring-loaded to facilitate opening the tools and maintaining the tools in a closed configuration.

A knife structure allowing rapid and safe replacement, and secure positioning of, a blade disposed along with its handle structure; wherein the knife structure includes the blade, an engaging and pushing plate, and an engaging and positioning base; a first connecting member is fixed to the engaging and pushing plate and is movably engaged in the blade and the engaging and positioning base; an engaging block is fixed to the engaging and positioning base and is movably engaged in the blade and the engaging and pushing plate; and the first connecting member is locked to the engaging and positioning base upon assembly of the knife structure. Once unlocked via a pushing and unlocking key, the first connecting member can be used to push the engaging and pushing plate and the blade simultaneously, allowing the blade to be pushed out of engagement with the engaging block and then detached for replacement.

A folding knife configured for safe and rapid disassembly and reassembly includes an upper handle portion having two engaging grooves respectively adjacent to its two ends, and a lower handle portion having an engaging and pivotally connecting shaft and an engaging and locking shaft respectively adjacent to its two ends. The two shafts are engageable in the engaging grooves respectively. A blade is mounted around the engaging and pivotally connecting shaft and rotatable into and out of a space between the handle portions. A pushable locking member is rotatably connected to the engaging and locking shaft and can be pushed to allow or prevent disengagement between the engaging and locking shaft and the corresponding engaging groove. Thus, user only has to push the pushable locking member, the upper handle portion and the blade will be in a detachable from or securely connected to the lower handle portion as a whole.

A folding knife includes a blade, first and second handle portions, a post, and an engaging plate. The post extends from the first handle portion. The blade is pivotable relative to the handle portions about a pivot axis between open and closed positions. The engaging plate is coupled to the second handle portion and is movable relative to the second handle portion between first and second positions. In the first position, the engaging plate engages the post, thereby restricting relative movement between the first and second handle portions in a direction parallel to the pivot axis and retaining the blade between the first and second handle portions. In the second position, the engaging plate disengages the post, thereby allowing relative movement between the first and second handle portions in the direction parallel to the pivot axis and allowing the blade to be separated from the first and second handle portions.
