Description
Background of the Invention
This invention relates to hunting knives, and relates more particularly to a combination of larger and smaller hunting knives compactly arranged as a unitary article, yet which knives are useful independent from one another.
For hunting, field dressing and other similar purposes, distinctly different types of knives are required to accomplish different purposes. For field dressing or taxidermy operations, for instance, a large, relatively broad bladed, strong knife is necessary for large cutting, skinning, etc. A smaller, scalpel-type knife is required to accomplish the more delicate tasks relating to preparation of a game animal head, particularly in areas of the eyes, ears, nose,mouth, etc. Compactness, ease and efficiency of operation, as well as safe and secure portability are highly advantageous features for such types of knives.
Exemplarly of prior arrangements for combining different utility tools may be found in the following U.S. Pat. Nos: 2,105,239 of Bachtold; 2,397,875 of Marshaus; 2,545,121 of Szopa; 3,252,489 of Huston et al; and 3,613,289 of Mozey, Jr. None of the above references disclose arrangements with the structural features and attendant advantages associated with the present invention.
Summary of the Invention
It is a primary object of the present invention to provide an improved combination hunting knife apparatus which comprises a pair of nested, smaller and larger knives wherein the smaller knife is completely contained and carried within the handle of the larger knife, yet which handle of the larger knife is so relatively configured to facilitate simple and easy removal and insertion of the smaller knife such that the larger knife may be used completely independently of the smaller knife and regardless of whether or not the smaller knife is being carried therewithin.
More particularly, an important object of the present invention is to provide a nested hunting knife apparatus as set forth in the preceding paragraph, wherein the larger knife handle comprises a pair of spaced, elongated tangs defining an elongated, open sided groove therebetween into which the smaller knife snugly fits, the open sides of the groove facilitating easy and convenient insertion and removal of the smaller knife.
Another important object of the present invention is to provide a pair of hunting knives, the smaller one of which is storable within the handle of the large knife, wherein is provided an improved, integrally formed detent mechanism of vastly simpler and more economical structure which does not detract from the aesthetic features of the overall knife.
Another important object is to provide nested hunting knife arrangement as set forth in the preceding paragraphs wherein the two knives are relatively configured and arranged to provide substantially complete protection for the honed edge of the blade of the smaller knife.
These and other more particular objects and advantages of the present invention are specifically set forth in or will become apparent from the following detailed description of a preferred embodiment of the invention when read in conjunction with the accompanying drawing.

Detailed Description of the Preferred Embodiment
Referring now more particularly to the drawing, there is illustrated a combination hunting knife apparatus generally denoted by the numeral 10 which includes a larger hunting knife 12 of generally thin, elongated, slightly curved structure having a blade portion 14 at one end and a handle portion 16 at the other end. Handle portion 16 includes a pair of laterally spaced, complementally curved, parallel, upper and lower tangs 18 and 20 defining an elongated, longitudinally extending, open space or groove 22 therebetween. Preferably, the blade and handle portions 14 and 16 are integrally formed from a single piece of steel. The handle portion 16 further includes guide means or side support elements including a pair of guard bolsters 24 secured, such as by a plurality of rivets 26, to opposite transverse sides of the larger knife in the area of the handle portion adjacent the blade portion 14. By appropriaate plating or other finishing technique to the outer surface of bolsters 26, the rivets are covered and hidden to enhance the eye-pleasing appearance of the apparatus as shown in FIG. 1. Guard bolsters 24 enclose the sides of and define a first section 28 of groove 22 at the end thereof proximate the blade portion 14. The handle portion 16 further includes a second guard means or side support elements in the form of a pair of rearwardly located pommell bolsters 30 secured by rivets to both upper and lower tangs 18 and 20 at the remote end of the hand portion. Similar to the guard bolsters, the pommell bolsters 30 enclose the open sides of and define a second section 32 of groove 22. It will be noted that the end of groove 20 at section 32 is open.
At the remote end of handle portion 16, the upper tang 18 has a relatively deep, longitudinal slit 34 to define detent means in the form of an elongated, thin, resilient cantilever 36 whose inner end is integrally formed with and permanently secured to upper tang 18. Cantilever 36 is hardened and tempered to present a leaf spring. The outer end of cantilever 36 is thus resiliently shiftable in a lateral direction toward and away from tang 20 and includes a detent in the form of a locking projection 38 firmly affixed to cantilever 36.
It is important to note that the above described configuration of handle portion 16 of the larger hunting knife provides a groove 22 which has side support elements at opposite ends thereof but which, between the side support elements 24 and 30, has completely open sides.
Apparatus 10 further includes a second, smaller scalpel knife 40 preferably made as a unitary article with integral blade and handle portions. Knife 40 is completely separate from larger knife 12. Thus, each knife 12 and 40 has its own blade and handle portions to allow use independently of the other. Smaller knife 40 is configured and arranged relative to the larger knife so as to be snugly received within groove 22 in its stored disposition as illustrated in FIGS. 1 and 3. The handle portion of scalpel knife 40 is curved complementally to the upper and lower tangs 18 and 20 to be snugly received within groove 22. Preferably, the blade portion of scalpel 40 is of slightly less lateral width than its handle portion so that the lower surface 42 of the handle portion of the smaller knife rides upon the lower tang 20 to place the honed knife edge 44 of the smaller knife in spaced disposition from the handle portion 16 of the larger knife. In this manner it may be assured that the honed knife edge is protected from contact with the metal surface and the larger blade while therewithin or during insertion and removal of the smaller knife. For further protection of the blade portion of scalpel knife 40, an insert 46 of rigid, blade protecting material such as fiberglass, polytetrafluoroethylene or other equivalent material is firmly secured to handle portion 16 to substantially fill the first section 28 of groove 22. Insert 46 is provided with an elongated aperture 48 which snugly receives the tip end of the blade portion of the smaller scalpel knife in surrounding, protective relationship upon placing the smaller knife in its stored position. Similar to the larger knife, the smaller knife 40 may preferably be configured with a finger receiving depression 50 as well as a plurality of transverse holes 52 which function for aesthetic purposes as well as to reduce and/or control the weight and balance of the smaller knife while permitting it to be formed as an integral, unitary body.
In use, smaller knife 40 may be easily and smoothly inserted into the larger knife to its stored disposition by passage through the remote, open end of groove 22, through section 32 of groove 22, and to the stored position substantially completely contained within the handle portion 16 of the larger knife. The tip end of the blade of the smaller knife is snugly carried within aperture 48 of insert 46. Upon complete insertion of the smaller knife, the resilient cantilever 36 shifts laterally downwardly such that projection 38 snaps over and engages the outer end of the smaller knife to retain or substantially lock the smaller knife in its stored disposition. The detent means securely retains the smaller knife within the larger knife not only to permit easy and safe portability of the unit, but also with sufficient securement to permit normal usage of the larger hunting knife while the smaller knife is stored therewithin.
The smaller knife is simply, quickly and easily completely withdrawn from the larger knife by shifting the cantilever 36 slightly upwardly to clear the smaller knife. Bolsters 24 and 30 smoothly guide knife 40 longitudinally along groove 22. Through the relatively expansive open sides of groove 22 between the guard and pommell bolsters, the smaller knife can be readily and easily grasped to facilitate simple removal of the smaller knife from the larger knife. Upon such removal, the larger and smaller knives 12 and 40 may be used independently of one another.
From the foregoing it will be apparent that the present invention provides an improved combination hunting knife apparatus which includes a pair of completely independent, separately useful knives, one of which can be substantially completely carried inside the handle of the other, yet which provides a simple, easy, and effective method of inserting and removing the smaller knife from the larger knife. At the same time the apparatus provides such advantages without incorporation of other retaining elements which must be removed from either the knives, which elements would thus subject to loss and/or damage that would render the unit completely inoperative. At the same time, however, the present invention provides such appartus with aesthetically pleasing and highly utilitarian design characterized by clean, unencumbered lines.
Various modifications and alterations to the specific arrangement illustrated will be apparent to those skilled in the art. Accordingly, the foregoing detailed description of a preferred embodiment of the invention should be considered exemplary in nature and not as limited to the scope and spirit of the invention as set forth in the appended claims.
