Abstract
Abstract A compact combination tool set providing a complete set of tools such as screw drivers, wrenches, knives, utensils or combinations of such devices is provided. The set comprises a plurality of inter-fitting tool segments, each tool segment having a tool or connecting shank projecting from one end thereof and a recess at the other end thereof adapted to receive a tool or shank projecting from one end of a second tool segment, said recesses and said projecting tools including portions which are noncircular in cross-section and which are adapted to be telescopically and frictionally inter-engaged so as to prevent relative rotation thereof, whereby a plurality of tool segments may be selectively inter-fitted for compact storage, and selectively separated for use. The tool segments in one embodiment have shanks which are of the same length and cross-section whereby tool segments of different sizes are selectively interengageable with each other or with an associated handle means.

Claim 3
Dependent Claim
26 words
A compact combination tool set according to claim 1, each of said tool segment recesses being configured as a wrench socket at the other ends thereof.
Claim 4
Dependent Claim
197 words
A compact combination tool set comprising: a plurality of inter-fitting tool segments; each tool segment having a tool projecting from one end thereof and a recess at the other end thereof adapted to receive a tool projecting from one end of a second tool segment; said recess being configured as a wrench socket at the outer end thereof; said recesses and said projecting tools including portions which are non-circular in cross-section and which are adapted to be telescopically and frictionally inter-engaged so as to prevent relative rotation thereof. each of said projecting tools being of the same length and cross-section and each of said recesses being of a length sufficient to fully receive said tools therein; whereby a plurality of tool segments may be selectively inter-fitted for compact storage, and one tool segment selectively separated therefrom, and inter-engaged with said other tool segments at one end of said plurality of inter-fitted tool segments, for use thereof; each of said tool segments having a transverse bore therein adapted to receive a shank of a tool projecting from any one of a second tool segment whereby said second tool segment provides a handle for the application of torque thereto.
Claim 5
Dependent Claim
