Embodiment Construction

[0017] Referring now to the drawings, the same or similar parts are designated by the same reference numerals throughout the various views. First refer to figure 1 , Reference numeral 10 represents a multifunctional knife that can replace different styles of blades.

[0018] Utility knife 10 with interchangeable blade styles includes a generally elongated handle 12 defining an axis A having a proximal end 12a, a distal end 12b, an upper edge 12c, and a lower edge 12d. An optional handle extension 14 is fixed to the handle 12 but is pivotally mounted thereon by a pivot 16 to allow the extension to pivot from the position shown when the handle is provided with an internal cavity (not shown) Approximately 180° to the retracted position in the handle.

[0019] The blade holder 18 has a blade support portion 18a substantially along the handle upper edge 12c and is configured to be attached to and detached from the handle 12 along a parting line 20 to selectively position the blad...

Abstract

An interchangeable different style-blade utility knife includes an elongate handle having a proximal end and a distal end along a handle axis. A blade holder is provided for supporting a blade, and actuating means is provided on the handle for selectively attaching and detaching the blade holder to the distal end of the handle at a parting line. A blade is supported by the blade holder and has an exposed cutting edge generally along a lower side of the handle and has a projected predetermined length along the axis. The blade holder has a support upper portion generally along an upper side of the handle and has a projected length along the axis substantially equal or generally proportional to the predetermined length to provide support for the blade. A kit includes a plurality of blade holders each with a different style blade each blade holder having a support upper portion substantially proportional to the projected length of a blade cutting edge along the axis of the handle.

Description

technical field [0001] The present invention relates generally to utility knives, and more particularly, to a utility knife with interchangeable blades of different styles. Background technique [0002] Utility knives with replaceable blades are known. When the blades become dull, they can be easily replaced with similar blades. Multipurpose knives with replaceable blades are known, for example, US 4,180,909 discloses a knife with replaceable blades. US 6,701,626 also discloses a hand tool with different replaceable blades. US 4,425,709 discloses different blade types that are replaceable. US 2004 / 0163264 discloses a hand saw and different styles of blade sets receivable within the handle. In the aforementioned devices, the blade is relatively thick and no support is required on the side opposite the blade edge to prevent breakage. [0003] US 8,834,509 discloses a multifunctional knife with a replaceable tool holder. For example, the patent shows saws, knives, scraper...
