A folding knife light tool with an ergonometric handle in which an illuminating means whether an LED or light bulb or a laser light is incorporated into the handle housing in the spaces existing between the blade, the locking mechanism, and the handle. A knife handle is provided having a body contoured for the hand. The housing is made from one molded piece with a slit in the middle. The handle includes a pivot point for supporting a blade between the longitudinal sides or scales of the blades. A conventional locking or non-locking system is utilized for keeping the blade open once it is unfolded. When the blade is folded, a portion of the blade extends above the sides of the knife handle for digital engagement in the opening operation.
