Abstract
Abstract A fastening arrangement for plastics handles of scissors and equivalent in constructions in which the plastics handle is die-cast around a tang at the end of the blade-shaft. The tang has such a generally curved shape that on the outside of the blade-shaft there will be a rather thick plastics layer at the end of the tang, and, correspondingly, on the inside of the blade-shaft there will be a rather thick plastics layer at the root end of the tang.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
154 words
A fastening arrangement for plastics handles in cutting tools, such as scissors and pliers, comprising two blade-shafts pivotably fastened to each other, the handles being die-cast around the end portion of the blade-shafts, the arrangement comprising a tang forming said end portion of each blade-shaft and formed at its root end with a notch at the inner edge of the blade-shaft, which notch is filled with plastics to procide a relatively thick plastics layer on the inside of the blade-shaft at the root end of the tang, and said tang being generally curved so that the surface of the tang at the outer edge of the blade-shaft becomes progressively more distant from the direction of said outer edge so as to provide an approximately triangular plastics layer on the outside of the tang, said triangular plastics layer being of greater thickness at the outer end of the tang than at the root end thereof.
