ABSTRACT:
This invention relates to a utility knife having a handle with two or more angular bends. The utility knife has replaceable blade, which may be retractable, clamped in the nose of the knife handle. The knife handle is hollow and separable to accommodate the storage of spare blades in the handle. Most utility knives either have handles which are substantially straight or which have a single angular bend. These knives are more limited in their application or produce difficulty in cutting materials in an obstructed area. A knife having a handle with two or more bends enables the user to cut materials in close quarters or in obstructed areas with greater ease. Different handles provide greater reach or leverage under different circumstances. An alternative knife includes a handle with two or more angular bends, one of which is adjustable. This allows the user to select a configuration that offers optimum reach and leverage. A knife of this type is particularly useful in cutting around radiators, toilets, cabinets and appliances. Another alternative knife includes a handle with a nodule on the butt end opposite the blade end. This nodule aids the grip by the user.
