Abstract: A hand tool apparatus is disclosed as providing an elongate, adaptive ergonomic handle portion. In at least one embodiment, the handle portion provides a pair of opposing handle ends. At least one of the handle ends provides an instrument portion. An at least one bendable core is positioned between the handle ends, the at least one core capable of being selectively bent into a variety of desired shape configurations, and substantially maintaining those shape configurations until the core is intentionally bent into a different desired shape configuration. As a result, the handle portion is capable of ergonomically conforming to a hand of a user while shifting a weight, as well as instrumentation forces and fulcrum of the apparatus and encouraging proper positioning of the instrument portion during use of the apparatus, regardless of the specific procedure to be performed using the apparatus.
