Abstract

The present disclosure is directed to a seven-way combination tool allowing for separate use of each of seven different functional portions of the tool and having a central blade, with upper and lower surfaces one of which has a concave surface and its blade tip is beveled at the end opposite the handle. The tool handle has upper and lower portions, both of which are independently rotatable 360° and each of which has a polygonal opening to accommodate polygonal shafted screwdrivers of different head types. At the tip of the central blade are located tip angle edge portions of different areas. One of which is located adjacent to the concave surface of the blade.

Claims

1. A seven-way combination tool allowing for separate and independent use of each functional portion thereof comprising a central blade with upper and lower portions, the lower portion having a concave edge surface, and whose blade tip is beveled;

upper and lower tool handle portions both of which are rotatable 360°

independently of one another and each of which has a polygonal opening shaped to accommodate polygonal shafted screwdrivers of different head types; and

tip angle edge portions of different areas located at opposite edges of the tip of said central blade, one of which is located adjacent to said concave surface edge of said blade.

2. A seven-way combination tool as in claim 1 wherein said central blade portion on the reverse side of said blade beveled tip is flat.

3. A seven-way combination tool as in claim 2 where in said tip angle edge portion adjacent to said concave surface has a larger surface area than the other tip angle edge portion.

4. A seven-way combination tool as in claim 3 wherein said polygonal openings are hexagonal.

5. A seven-way combination tool as in claim 4 wherein one of said screwdrivers is of the slotted (flat) head type.

6. A seven-way combination tool as in claim 4 wherein another of said screwdrivers is of the Phillips head type.

7. A seven-way combination tool as in claim 4 wherein each rotatable handle portion contains an opening shaped for accommodating said screwdrivers, and retaining means for holding each screwdriver in place and readily allowing removal thereof.

8. A seven-way combination tool as in claim 1 wherein each rotatable handle portion contains a leaf spring with a central opening and detents to enable rotation of each handle portion independently.

9. A seven-way combination tool as in claim 8 wherein said central blade has a tang portion containing end openings at locations permitting positioning said detents therein.

10. A seven way combination tool as in claim 9 which includes adjustable securing means to secure said handle portions and leaf springs to said central blade via central openings therein.
