This disclosure pertains to a utility knife, and, more particularly, to a utility knife that can be used as a defensive weapon.
It is known to provide long single blade punch daggers with handles, some of which have blades offset from the center of the handle. Such daggers, however, require precision in use of the dagger, for if the blade point misses its target, the dagger is less effective as a defensive weapon. Further, such daggers are not very effective if swept across a target, for the point must be at a certain depth in the target to be effective. Furthermore, if the long blade enters its target at angle, the dagger punch is less effective.
What is needed is a knife like a punch dagger that requires less precision when hitting its target, exposes more blade edge when the knife is swept across its target, and which provides maximum force when punched forward. It would also be beneficial if such a defensive weapon could also be used as a utility knife.
Disclosed is a knife including a single triangle like steel blade with a pointed apex and sharp-edged sides and a hand wide base. The knife also includes an elongated handle attached directly along its length to the base, the handle having at least one finger opening adapted to allow at least one of a user's fingers to pass through the finger opening.
The exposed sharp edges on either side of the point assists with defensive use of the knife. When the knife is swung by a user to sweep an arc through the air, a maximum amount of sharp edge is presented. In the event of any attacker being in the area, the knife will slice as it sweeps through the arc, cutting anyone who might be in the vicinity. The shallow point of the knife also allows for the knife to be used for opening boxes, slicing fruit, or cutting through various materials, for example.
Before one embodiment of the disclosure is explained in detail, it is to be understood that the disclosure is not limited in its application to the details of the construction and the arrangements of components set forth in the following description or illustrated in the drawings. The disclosure is capable of other embodiments and of being practiced or being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. Use of “including” and “comprising” and variations thereof as used herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. Use of “consisting of” and variations thereof as used herein is meant to encompass only the items listed thereafter and equivalents thereof.
As illustrated in
More particularly, in the illustrated embodiment, the right-angle apex 20 is 2 inches high (see H in
In other embodiments (not shown), the handle can be separate from the blade and elongated and attached to the blade base along the handle length. In other embodiments (not shown), the edge of the handle and handle form adjacent the finger openings have scallops that receive a user's fingers.
To aid in the attachment of the handle form 60 to the handle 24, the handle 24 has three spaced apart holes 64 through which screws 68 can pass to hold the two sides of the handle form 60 together. There is also a large triangular opening 70 in the blade 14 and spaced apart holes in the handle 74 for reducing the weight of the blade 14.
“Hand wide” as used herein means wide enough to reach across the knuckles of the little, ring, middle, and index fingers of an adult hand, i.e., greater than 3 inches, but preferable 4.5 inches with the finger openings being 4 inches wide.
The knife 10 can be held in the hand in a position where the point of the triangular like blade aligns with the bones of the forearm. As a result, a thrust of the knife forward provides maximum force on the point the knife. The exposed sharp edges on either side of the point assists with defensive use of the knife. When the knife is swung by a user to sweep an arc through the air, a maximum amount of sharp edge is presented. In the event of any attacker being in the area, the knife will slice as it sweeps through the arc, cutting anyone who might be in the vicinity. The shallow point of the knife also allows for the knife to be used for opening boxes, slicing fruit, or cutting through various materials, for example.
