Small form-factor apparatus and methods for holding, securing, and accessing personal items normally carried on a keychain and in a wallet including, for example, keys, USB drive, bottle opener, driver's license, credit-cards, RFID cards and paper currency are disclosed.

A pocket tool (e.g. a key carrier) comprises two tool elements such as a bottle-opener/screwdriver blade and a carabiner clip pivotally deployable on opposite sides of a central handle plate. A spring bar mounted on one face of the central handle plate has a free end portion which engages diametrically opposed flats formed on camming surfaces of root portions of the carabiner clip and bottle-opener/screwdriver blade respectively in order to hold them in their retracted and deployed positions. The free end portion includes a transverse projection which extends through a cut-out or aperture to enable it to engage the camming surface of the carabiner clip, enabling control of two tool elements on opposite sides of the central handle plate. When one tool element is held in the deployed configuration the other tool element is held in the retracted configuration.

According to an exemplary embodiment, a key holder may be provided. The key holder may include a first element and a second element, having at least two holes disposed therethrough. The first element and the second element may be mounted on at least two key retention posts that may be configured to be inserted in the first element and the second element, thereby connecting the first element to the second element. A number of washers and accessories may be rotatably mounted on the key retention posts between the first and the second element. A clip may be inserted into an opening in at least one of the first element and the second element and may be connected to one of the of key retention posts.

A key storage device, includes a first panel, a second panel, a limited post and an elastic part. One end of the first panel is rotatably connected with one end of the second panel through a shaft lever, and a storage space for storing tools is formed between the first panel and the second panel. One end of the elastic part is arranged on the first panel or the second panel, one end of the limited post is connected to the second panel, the other end of the limited post is detachably arranged on the first panel, and the elastic part is configured to compress the tools when the tools are stored by the key storage device.
