发明名称 Key concealment attachment
摘要 An attachment to a key to facilitate concealment of the key, which takes the form of a bifurcated housing within which is embedded magnetic material. The bifurcated housing includes a fastener, which in operation passes through an opening formed within the large handle section of the key. The exterior sidewalls of the bifurcated housing deflect to become recessed during operation of the fastener to thereby form recessed areas to facilitate grasping and holding of the attachment thereby facilitating operation of the key.
