     BACKGROUND OF THE INVENTION 
     1. The Technical Field of the Invention 
     The disclosure generally relates to set of tools for food handling during grilling process and more specifically to the set of two tools where one is a fork and the other is a knife that work also as spatulas, and while both are interlocked together, they work as tongs, as a grill scraper, and grill grasper. Fork&#39;s body contains a can opener while knife&#39;s body contains juice can piercer and beer bottle opener, therefore together work as one multifunctional BBQ tool. 
     2. Description of Related Art 
     In one approach set of tools used for barbecue contains tongs, fork, hook, and spatula that may work as a knife. A set has also a bear bottle opener. Tongs, fork, spatula, and hook used separately or simultaneously with one other tool, require the other tools to store somewhere close by. 
     In another approach spatula alone works as fork or knife and often contains a beer opener. The problem with such approach is that a cook-operator still needs to use either tongs and separate fork or knife to manipulate a grilling food. 
     Yet another approach is to provide universal handles with exchangeable inserts that each performs a different function. The problem with such approach is that exchangeable parts have to be stored somewhere during food preparation so the parts may be easily misplaced. The other problem with such approach is that parts after initial use are not clean anymore and placing them back in the storage container or handling them afterward is not convenient. 
     Another approach is using the tongs of which one arm works as a knife and the other as a fork. The problem with such approach is that fork should be stationary during cutting with a knife so while the arms are not separable—additional tool is necessary. 
     Yet another approach is to separate both parts of tongs by utilizing spring loaded connection with oftentimes complex mechanism that lowers reliability of such tool. 
     Therefore, it is apparent that there is a need for a barbecue tool, which is cost-effective, easy to manufacture and store, and while used outside, to efficiently perform multiple and necessary functions, while also being compact enough to keep it in the usually limited storage space around BBQ. 
     BRIEF SUMMARY OF THE INVENTION 
     The present apparatus and methods described here in preferred embodiment meet the recognized need for basic barbecue tools in the form of knife and fork that each can work separately as spatula or, when interlocked together, can work as tongs. Cutouts placed in the foot sections allow resilient interlocking connection of both spatulas to function as tongs and allow hanging each tool separately or in one piece as tongs assembly. Sharp tools, namely a piercer and a can opener, are located away from contact with operator&#39;s hands ensuring safety of operation. 
     Patterns of knife-spatula and fork-spatula blank cuts from planar stainless steel sheet require additional operations such as sharpening edges, forming the cutouts of incorporated tools, bending, and connecting thermo-insulating material to become the finished product. 
     Tool grip of the handle contains two strips made from a thermo-insulating material in two different thicknesses: thin and thick, where thin strip is placed on the inner side of tool while a thick strip goes outside. 
     Stainless steel properties of knife and fork provide necessary resilience to operate tools assembled together as a tongs without any additional mechanism, added part, or process. 
     Cutting patterns integrated in the foot of tools allow forming can piercer in the knife and can opener in the fork. Sharp edges of the can opener and can piercer placed far from food handling parts stay clean unless being used accordingly. That way the sharp edges do not require the same amount of cleaning as the remaining parts of tools, lowering a chance of an unintentional injury to the operator. Foot ends of both knife and fork, usually directed towards the operator, are rounded to prevent injury from accidental piercing and ensure the tools&#39; safe use. Lip-bend of fork foot provides a bearing for edge of circular shape of knife foot and allows alignment of the top edge of the knife-spatula with the bend of the fork-spatula tips for use as a scraper, where the top edge of the knife-spatula cleans the top of the grill, while bent tips of fork-spatula clean sides of the grill when knife-spatula and fork-spatula are assembled as tongs and are in closed position. 
     Tips of fork-spatula, bent towards working space, while assembled in tongs, provide additional gripping power during food handling, and while tongs are in closed position, lower a chance of accidental piercing by teeth of the fork and prevent unintentional cutting by sharp edges of the knife-spatula. Lateral teeth of fork-spatula, being wide and having tips bent, work as hooks for handling the food.

     DETAILED DESCRIPTION 
     Use of actual terminology to describe exemplary and preferable embodiment of the present disclosure as illustrated in  FIGS. 1-11  does not exclude any or other technical terminology or limit processes or shapes to describe similar products, which may lead to accomplishment of similar shape, function or purpose, and to be limited only by listed claims. 
     Referring to  FIG. 1 , elongated pattern cutout from the planar stainless steel sheet after being mechanically formed and processed to work as a knife that functions also as a spatula has three parts distinguished by shape, function, and purpose.
         A head of a knife-spatula  1  has two lateral edges  5  that while sharpened work as left-handed and right-handed knives. Top edge  6  of knife-spatula works as a part of a scraper and oblong cutouts  7  work as a meat juicer. Transitional trapezoidal shape of the knife-spatula is a part of the head. Obtuse angles of bend  1   b  and  1   a  place spatula away from the body to create food-handling space and enhance scooping of grilled food.   A handle works as a tool grip with a thin strip  3  of thermo-insulation material placed at the food handling side, and a thick strip  4  placed at the opposite side.   A foot works as an interlocking device and as a pivot for fork-spatula  2 . A can piercer located below the handle on the side of the thick strip  4  is formed from the pattern cutout. The rounded foot works as a bottle opener and one part of the two-part grill grasper.       

     Referring to  FIG. 2 , elongated pattern cutout from the planar stainless steel sheet, after being mechanically formed and processed to work as a fork that functions also as a spatula, has three parts distinguished by shape, function, and purpose.
         A head of a fork-spatula  2  has multiple cutouts to form the shapes of teeth  8  and  9  along the top peripheral edge, where wide lateral teeth  9  are working as a hooks. Tips  10  of all fork teeth are bent not more than seven degrees in the direction of food handling side and provide better food grip without diminishing piercing ability of a fork and also work as a part of scraper.
 
Transitional trapezoidal shape of the fork-spatula is a part of the head. Obtuse angles of bend  2   b  and  2   a  move spatula away from the body to create food-handling space and enhance scooping of grilled food.
   A handle works as a tool grip with a thin strip  3  of thermo-insulation material placed at the side of food handling, and a thick strip  4  placed at the opposite side.   A foot works as an interlocking device and yoke for knife-spatula  1 . A can opener located below the handle on the side of the thick strip  4  is formed from the pattern cutout. The rounded foot of fork has projection-bend  19  and lip-bend  20 , and while bent in such way that lip-bend  20  is perpendicular to the foot and is offset by projection-bend  19  from the foot at the resulted distance, provide alignment for heads of knife-spatula  1  and fork-spatula  2  in the assembly of tongs used as a scraper.       

       FIG. 3  illustrates a view of detail “A” of knife-spatula  1 , where the circular end of the foot works as a locking circular shape  11 , while cutout inside the circular shape works as a bottle opener  12 . Shape of the cutout above the circular shape matches the yoke opening in fork-spatula  2  where locking neck  16 , locking edge  17 , and locking support edge  18  together function as a pivot. Can piercer is formed from the pattern of a can piercer cutout  13  located above the yoke and projecting on a side of the thick strip  4 . A can piercer sharp edge  14  is formed from an upper cutout shape, while a can piercer lip  15  is formed from lower cutout shape. 
       FIG. 4  illustrates a view of detail “B” of fork-spatula  2 , where the yoke at the foot section consists of two types of shapes: vertical aperture  24  that accommodates the size of locking circular shape  11  of knife-spatula  1 , and a rectangular cutout  26  that functions as a yoke. The length of the yoke horizontal edge  25  corresponds to the width of locking neck  16  in the foot of knife-spatula  1 . The pattern cutout  21  for can opener located in the fork-spatula  2  above the yoke provides upper cutout shape to form can opener sharp edge  22  and a lower cutout shape to form the can opener lip  23 , that work together as the can opener that is accessible from the side of the thick strip  4  of a handle. The rounded foot section of the fork-spatula  2  has two bends in the same direction as bends of can opener. The fork projection-bend  19  ensures the correct placement of the lip-bend  20  to work as a bearing for locking circular shape  11  of the knife spatula  1  in tongs assembly used as a scraper, and as a grasping face in a grasper illustrated in  FIG. 11 . 
     The following figures illustrate the two step process of interlocking fork-spatula and knife-spatula to work as tongs, where:
           FIG. 5  illustrates the first step when foot in circular shape  11  of knife-spatula  1  passes from the side of working space to the opposite side of the fork-spatula  2  through the elongated vertical aperture  24 .     FIG. 6  illustrates the second step, where foot in circular shape  11  of knife-spatula  1  is clear on the other side of fork-spatula  2 , and locking neck  16  of knife-spatula  1  is turned in the rectangular cutout  26  of the fork-spatula  2  and ready to work as tongs utilizing resilient fixed connection between feet of fork and knife.     FIG. 7  illustrates the tongs assembly in open position, where the interaction of fork lip-bend  20  of fork-spatula  2  and locking circular shape  11  of knife-spatula  1  ensures the relative position of both spatulas.       

       FIG. 8  illustrates the tongs assembly in closed position in a diametric view from the fork-spatula  2  side with an indication of the detail “C” and relative position of circular shape  11  of knife-spatula  1  and fork lip  20  of fork-spatula  2  at the foot. Tongs works as a scraper only while food-handling spaces of both tools face each other and are in closed position. 
       FIG. 9  illustrates the detail “C” of tongs assembly in diametric view from the fork-spatula  2  side, where bends of tips  10  of fork-spatula  2  are aligned with peripheral top edge  6  of knife-spatula  1 . Closed tongs works as a scraper, in which side edges of tips  10  clean sides of a grill and peripheral top edge  6  cleans top of a grill. Wide lateral teeth  9  work as hooks when fork-spatula  2  is used individually. 
       FIG. 10  illustrates the tongs assembly in diametric view in open position for use as a grasper with indication of the detail “D”. 
       FIG. 11  illustrates the detail “D” of tongs assembly used as a grasper, where: fork projection-bend  19  with fork lip-bend  20  grasps, and together with the circular shape  11  of knife-spatula  1 , holds an edge of a vessel, container, grill, or plate. Fork lip-bend  20  also guides the locking circular shape  11  and prevents misalignment of the knife-spatula  1  and fork-spatula  2  in tongs assembly. 
     The above embodiment of the invention of BBQ convertible tongs, in which the scope of the invention is described and illustrated hitherto, is determined by the appended claims.
