A multi-purpose tool includes a first handle, a second handle, and a laminated plier jaw assembly coupled to the first handle and the second handle. The laminated plier jaw assembly includes a first outer layer, a second outer layer, an inner layer, and a pin. The first outer layer defines a first aperture. The second outer layer defines a second aperture. The inner layer is positioned between and is coupled to the first outer layer and the second outer layer. The inner layer defines a slot having a narrow portion positioned between a first wide portion and a second wide portion. The pin extends at least partially through the first aperture, the second aperture, and the slot. The first outer layer, the second outer layer, and the inner layer cooperate to define a pair of jaws that rotate relative to one another about an axis of rotation.

A knife handle comprising a handle body with a proximal end and a distal end, a sharpener body removably attached to the handle body, the sharpener body comprising at least one cut-away for housing a replaceable sharpener, the sharpener body rotatable relative to the handle body, and a selectively actuatable locking mechanism for locking the sharpener body in place on the handle body. The selectively actuatable locking mechanism may have a first, locked position wherein the sharpener body cannot rotate relative to the handle body and a second, open position wherein the sharpener body can rotate relative to the handle body. The selectively actuatable locking mechanism may be biased in the first, locked position.

An extendable-retractable pet leash includes a housing with a spring-actuated take-up reel. A personal protection device is mounted on the housing and can comprise, for example, an extendable-retractable knife, a taser or a siren. The housing also mounts a light for illuminating a surrounding area. The leash, personal protection device and light can all be operated by actuators mounted on the housing for convenience, one-handed operation.
