Abstract
Abstract Disclosed herein is an illuminated multifunctional pocket knife/light. The casing or handle has at least one hollow channel within which is disposed at least one light bulb, and one power source out of contact with one another. Activation of switch completes electrical circuit thus activating the light source/s. Alternative embodiments illustrate different positions for various switch components. The handle can be partially or entirely constructed from a light transmissive or optical wave dispersing material which guides light through the handle and assists in illuminating the blade/implement and its surrounding work surface. The casing supports the desired tool/implement in the field of light. The casing houses at least one chamber in which one or more blades/implements are connected. Blades/implements are fixed in permanent position or folding/collapsible for the purpose of storing and protecting the implements until use. Alternative embodiments further illustrate that blade/tool fixtures may be either locking or non locking. Alternative embodiments also illustrate that flashlight, compass, whistle, survival capsules and weighing scale are detachable or permanent components of the casing. The compass module is a cap housing a light source and a liquid or dry chamber in which a translucent dial is seated.
