Aspects of the present disclosure generally pertain to an apparatus and method for holding a key for self-defense. Aspects of the present disclosure more specifically are directed toward a self-defense key holder or an apparatus that rapidly converts a key (e.g., house key) into a fighting weapon, for example, for self-defense. The defense key holder may utilize an existing key (e.g., home/office/auto) to replace bulky and often prohibited self-defense aids. This disclosure may be useful for giving a user additional control and force in a variety of motions with a key or other object.

A self-defense apparatus includes a sleeve portion and an adapter connected to the sleeve portion. The sleeve portion includes a proximal end surface, an outer side surface, and a distal end surface. The sleeve portion defines an implement-receiving cavity that extends axially into the proximal end surface. The sleeve portion defines an adapter-receiving passage that extends axially into the distal end surface. A proximal portion of the outer side surface defines a handle portion that includes one or more finger grooves. A distal portion of the outer side surface defines an adapter-interfacing body. A first portion of the adapter body is disposed within the adapter-receiving passage. A second portion of the adapter body extends beyond the distal end surface. A distal portion of the second portion of the adapter body defines a conical body.

An apparatus for an accessible extreme close quarter penetrating self defense weapon. It is comprised of a cast rigid urethane resin. It is cylindrical in shape, approximately five and three quarters (5) inches long, five eights () inches wide, two (2) inches in circumference, and thirty four (34) grams in weight. One end is flat with a small hole approximately three sixteenths ( 3/16) inches in diameter drilled completely through it so that a steel cable key ring can be attached. The other end tapers to a point from which the sharpened tip of a five and one eighth (5) inch long and three sixteenths ( 3/16) inch diameter steel rod protrudes. The outside surface is either smooth or textured and is indented by six (6) grooves approximately three quarters () inch apart. The apparatus comes in many colors created by the addition of dye and or other coloring products during the casting process of the rigid urethane resin. Coloring of the apparatus is further enhanced by the application of various colors of paint to the outside surface.

A modular tool including a first member and a second member each including a head portion, a shaft portion and a handle portion. The first member includes a first member slot and the second member includes a second member slot. A connector includes fasteners and a pair of locking tabs. Each of the locking tabs includes a pair of locking tab openings. The first member and the second member interlock via the first member slot and the second member slot. The pair of locking tabs are disposed within a pair of locking tab slots and the fasteners run through the pairs of locking tab openings and a pair of member openings, thereby locking the first member to the second member.
