     DETAILED DESCRIPTION OF THE INVENTION 
     Throughout the description, the following terms are used:
     cartridge opener  2 ,   bottle cap  4 ,   bottle  6 ,   casing  8 ,   aperture  10 ,   tooth  12 ,   bullet  14 ,   rim  16 ,   bullet end  18 ,   primer  20 ,   shoulder  22 ,   cannelure  24 ,   neck  26 ,   magnetic surface (i.e. refrigerator)  28 ,   magnet  30 .   stopper  32 .   

       FIG. 1  is a contextual drawing that shows the cartridge opener  2  of the present invention as it is typically used to open a bottle cap  4  on a beverage bottle  6 . While outward appearances are that of a rifle cartridge, there is a cut out in the casing which permits efficient opening of the bottle  6 . As depicted, the user may invert the cartridge and removably secure a “tooth” disposed in a cut out (aperture  10 ) of the cartridge under the bottle cap  4 . From that point, user has a very efficient lever to swiftly remove a bottle cap  4 . The aperture  10  is ideally suited to accommodate the bottle cap  4  of a bottle, which may be fitted therein and securely engaged and then leveraged off the bottle. 
       FIGS. 2 and 3  provide additional detail of preferable embodiments of the present invention. As shown, a preferable embodiment is that of a typical .50 caliber rifle cartridge. This is a rifle round that is ell-respected in shooting communities, but also has sufficient weight and size to be an ideal lever for the purposes of the present invention, once suitably modified. The cartridge features a bullet  14  (typically with a full metal jacket). This is disposed at the bullet end  18  of the cartridge. The cartridge has a casing  8  which forms the main body of the cartridge opener  2 . Toward the rear of the rifle cartridge is disposed a rim  16 , which also features a primer  20 , which has been expended. Of course, this particular cartridge will not feature any gunpowder since the purpose of the cartridge is not actually for deployment in a weapon, but is for the purpose of recreation and opening beverages in an efficient, gratifying and stylish manner. Disposed in the rearward portion of the casing  8  is an aperture  10 . The aperture  10  is generally cut in the shape of a square or a rectangle. An important feature of the aperture  10  is what is referred to as a tooth  12 , which is situated on the bullet end  18  of the aperture. Other typical features of a rifle cartridge are shown in  FIG. 3 , namely the shoulder  22 , the cannelure  24  on the bullet, as well as the neck  26  of the cartridge. The shoulder  22  and neck  26  of the cartridge are part of the casing  8 . 
       FIGS. 4 and 5  are important in as much as they show preferable dimensions of the aperture  10  of the present invention as well as preferable dimensions of the tooth  12 . A properly sized aperture is important because it must accommodate for the size of a typical bottle cap  4  on a bottle  6  such as a beer or soda bottle. It rust have appropriate dimensions, yet, the casing  8  and the tooth  12  must have adequate size to properly lever on the bottle cap  4 . Applicant has found a .50 caliber cartridge to be of an ideal size for purposes of opening a bottle. Applicant has determined that one preferable range of length (meaning lengthwise along the cartridge) for the aperture  10  is in the range of 0.5-1.0 inches in length. Still, more preferable is a length of 0.875 inches. A preferable size for the gap between the top of the tooth  12  and the top of the aperture  10  is at least 0.5 inches. More preferable still, is a gap of 0.625 inches. The tooth  12  is preferably of a length of at least 0.2 inches with a still preferable size being that of 0.245 inches and with the preferable width of at least 0.2 inches and more preferable still, a width being 0.307 inches. The length and the width of the tooth  12  is an important factor because if it is too wide it will obstruct the bottle cap  4 , whereas if it is too narrow it will not adequately leverage the bottle cap  4  on a bottle or it will slide off, which can be an annoying experience for the user. The tooth  12  is beneficial because it allows both a proper overall size opening and yet accomplishes excellent leverage and grip. Overall, the aperture  10  may be cut to an approximate midpoint of the casing  8 , which is seen in  FIG. 4  and  FIG. 5 . As may also be seen, the aperture  10  is disposed toward the rearmost portion of the casing  8 . One preferable placement for the opening for the aperture  10  is 0.5 inches from the rim  16  of the cartridge opener  2 . Applicant has determined that this orientation provides the best weight and leverage considering the considerable weight of the bullet  14  disposed at the opposite end of the casing  8 . particularly, on a .50 caliber cartridge, the weight and leverage angle provides an ideal experience and comfort in the hand of a user. Also, the disclosed orientation and position on the aperture  10  provides for great ease of removal of a bottle cap with minimal force using the wrist. 
       FIGS. 6 and 7  simply show the top and bottom views of the cartridge opener  2  of the present application. 
       FIG. 8  is a perspective view that shows the various aforementioned features of the cartridge opener  2 . From this vantage point, it is also possible to see how the aperture  10  on a .50 caliber bullet is particularly suited to provide adequate space to accommodate the bottle cap  4  on a typical beer or soda bottle. Other cartridge sizes are contemplated; however, a .50 caliber cartridge is most preferable. 
       FIG. 9  represents another embodiment of the cartridge opener  2  of the present application and depicts the apparatus as it may be used and secured to a magnetic surface  28 , such as a refrigerator. Persons looking to open a beverage with a bottle  4  typically want to open the beverage near the refrigerator  28 . Rather than fumbling around in drawers or in other locations, the applicant has determined that attachment to a refrigerator&#39;s magnetic surface  28  or a nearby metal surface is preferable. In the context of a .50 caliber bullet cartridge, which has a considerable weight, magnetic attachment without impeding the aperture  10  must be done correctly. The magnet must be a suitable strength to hold the considerable weight of the cartridge and it must be properly positioned to prevent undesired sliding of the cartridge opener  2 . 
       FIGS. 10 and 11  show one preferable placement for a magnet  30  to secure the cartridge opener  2 . These figures show an embodiment where the magnet is secured to the rear of the casing  8 . In this particular embodiment, the magnet is fixedly attached and protrudes out of the rear casing  8 . The magnet  30  is typically a “super” magnet. These are often neodymium disc magnets. 
     As shown in  FIGS. 12 and 13 , a magnet  30  is preferably centrally disposed or slightly offset from a midpoint of the casing  8  on the side opposite of the aperture  10 . 
       FIG. 12-16  are perspective drawings that show the appearance in three dimensions of this embodiment with an externally located magnet  30 . 
     In yet another embodiment of the present invention, a magnet  30  is fixedly disposed internally of the casing  8  of the cartridge opener  2 . A cartridge with magnetic properties may be fashioned by disposing one or more magnet(s)  30  inside the casing  8  and then securing the magnet(s)  30  with an adhesive means, which may be secured either below, around, or on top of the magnet(s). One preferable location for securing such a magnet is toward the shoulder  22  inside the casing  8 . Adhesive may be injected through the aperture  10  on top and/or around the magnet  30 . The magnet  30  may be internally fixed anywhere along the inside casing although applicant has found it preferable to secure the magnet  30  in a manner that when the cartridge is fixed on a magnetic surface, such as a refrigerator  28 , the aperture  10  faces outward. The magnet  30  may be fixedly attached via insertion through the casing  8  with a properly sized cut out. The magnet  30  may also be secured via an epoxy substrate or adhesive. 
     Yet still another method of fabricating a magnetic version of this present invention is to obtain a cartridge opener  2  and insert at least one magnet (or preferably four) into the body cavity (casing) of the cartridge (typically toward the bullet end), and then plug the magnets inside the casing with a rubber/plastic stopper  32 . One preferable stopper/cap may be formed from vinyl, polyethylene, polypropylene or other soft plastic so that it is fashioned to accommodate the inner dimensions of the casing and so it will best hold the magnets  30 . The stopper  32  may be jammed down on the magnets with a wedge or instrument to hold them securely. This latter method is beneficial because it avoids the stickiness associated with glues and adhesives, and it preserves the overall shape of the cartridge while allowing it to be magnetized. 
     The cartridge opener  2  may be fashioned from a variety of materials, although, metal is preferred and in some cases chrome or other precious metals may be used or plated onto the cartridge opener  2 . some cases, powder coating and heat treatments may be used on the cartridge and particularly on or around the aperture  10  to prevent chipping or damage to the surfaces from repeated use with a bottle cap  4 . 
     It is to be noted respecting each of the foregoing descriptions that the appended figures illustrate only typical embodiments disclosed in this specification, and therefore, are not to be considered limiting of its scope, for the invention may admit to other equally effective embodiments that will be appreciated by those reasonably skilled in the relevant arts. The components in the figures are not necessarily to scale, unless otherwise noted, but with an emphasis instead being placed upon illustrating the principles of the invention.
