Abstract
A combination hand tool for cutting flexible duct and the like, which tool has both (i) a blade-holding mechanism which enables safe, quick and convenient replacement of a utility knife blade for cutting material requiring relatively low cutting pressure (e.g., the insulated portion of flexible duct) and (ii) a replaceable cutting tool having a cutting edge moveable against a cutting surface to enable the user to generate relatively high cutting force on a piece requiring such high cutting force (e.g., the metal or plastic wire component of flexible duct). In the preferred embodiment of the invention, the aforementioned blade-holding mechanism includes two similarly-shaped, overlying plates which are both pivotably moveable to enable separation of the plates and replacement of the utility knife blade positioned therebetween. Also, the aforementioned replaceable cutting tool is held in its operating position by a holding mechanism for releasably securing the cutting tool.
