Abstract
A cutting tool adapted to be reciprocated by a manually manipulated air hammer or similar device while being used to separate laminated materials. The cutting tool comprises a blade of thin resiliently flexible metal having a sharpened edge and an opposite driven edge, and an adapter comprising a blade holder portion which may include polymeric material permanently molded around a portion of the blade adjacent its driven edge, and a shank portion shaped for engagement by the air hammer attached to the blade holder that has an end shaped for engagement by the air hammer or similar device. The majority of or all of the adapter can be formed of the polymeric material to provide a low mass for the cutting tool and an average specific gravity for the adapter that is significantly less than the specific gravity of metal.
