Abstract
An ergonomic handle for use with a hand tool, such as a pair of scissors or the like, is disclosed which includes first and second opposing lever members coupled together at a pivot point to permit reciprocating movement of the lever members between a closed position and an open position. The lever members may include a cutting blade or other tool feature on a first end adjacent the pivot point, and a handle on a second end adjacent the pivot point opposite the first end. The fixed handle has a loop portion which includes an inner surface and an outer surface along one side of which abuts a corresponding outer surface of the opposing lever member while in the closed position. Each loop portion is made from a rigid material segment and a resilient material segment, with the rigid material segment having a cavity open at the outer loop surface and the resilient material segment extending across the cavity at the inner loop surface.
