Title: Scissors split into two kitchen knives

Description:
BACKGROUND OF THE INVENTION  
      (a) Technical Field of the Invention  
      The present invention is related to a pair of scissors, and more particularly, to one that can be split into two kitchen knives.  
      (b) Description of the Prior Art  
      Scissors and kitchen knives are a must in the kitchen to cut off the sealing bags of the edibles or to prepare cooking materials. However, the exchangeability between the scissors and the kitchen knife is unlikely since the kitchen knife is not so handy to cut off a plastic bag. Therefore, both of the scissors and a bunch of kitchen knives must be available by the sink; and one has often to search for a pair of scissors or a kitchen knife.  
     SUMMARY OF THE INVENTION  
      The primary purpose of the present invention is to provide a pair of scissors that can be split into two separate kitchen knives. One of the knives can also operate as a can opener and both respectively are handy for a right-handed or a left-handed user. To achieve the purpose, the scissors of the present invention is comprised of a first blade and a second blade overlapped and pivoted to each other. A cutting edge is provided on one side of each blade and both cutting edges are facing each other. Another heel extends from the distal end of a heel of the first blade. An angular plate is formed on the distal end of a heel of the second blade. The extended heel of the first blade is overlapped with the angular plate on the heel of the second blade. The heel of the second blade is strayed away at a certain inclination from the angular plate and protrudes beyond the heel of the first blade. The heel of the second blade is inserted into and secured in a ring handle, and the heel of the first blade is inserted into and secured in a bow handle. The bow handle strays away from a line extending from the cutting edge of the first blade.  
      A pivot axis provided vertically at its end a lateral bolt is disposed on the second blade at where the second blade is to be pivoted. An axial bore is provided on the first blade at where in relation to the pivot axis and the axial bore enters into or leaves from the lateral bolt at a given crisscrossing angle. With such a movable pivot mechanism, the pair of scissors can be split into two separate kitchen knives. Whereas both of the scissors and two kitchen knives share the same two blades, the user has two cutting tools in one piece without bothering to search for a pair of scissors or a kitchen knife.  
      Another purpose of the present invention is to provide a pair of scissors that can be split into two separate kitchen knives that also operate as a can opener. To achieve the purpose, a gap is formed on the cutting edge of the first blade. Accordingly, when the pair of the scissors is split into two kitchen knives, the first blade can also operate as a can opener.  
      The foregoing object and summary provide only a brief introduction to the present invention. To fully appreciate these and other objects of the present invention as well as the invention itself, all of which will become apparent to those skilled in the art, the following detailed description of the invention and the claims should be read in conjunction with the accompanying drawings.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
      The following descriptions are of exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.  
      Referring to  FIG. 1  for a perspective view of a pair of scissors of the present invention,  FIG. 2  for a schematic view showing the process of turning over a first blade, and  FIG. 3  for a schematic view showing the process of turning over a second blade; wherein, the pair of scissors of the present invention that can be broken down into two kitchen knives is comprised of a first blade  10  and a second blade  20  with both overlapped and pivoted to each other. At where both blades  10 ,  20  clamping against each other, a cutting edge  11  ( 21 ) is formed at a certain inclination on one side on the back of the first blade  10  ( 20 ). Another heel  13  extends from the distal end of the cutting edge  11  on the first blade  10  at where close to a hell  12  while an angular plate  24  to be overlapped with the heel  13 is formed on the distal end of the blade back  22  of the second blade  20  at where close to a heel  23 . The heel  23  of the second blade  20  is strayed away at a certain inclination from the angular plate  24  and protrudes beyond the heel  12  of the first blade  10 . Similar to a pair of sewing scissors, a bow handle  30  and a loop ring handle  31  are provided to the scissors of the present invention. The heel  23  of the second blade  20  is inserted into and secured by the ring handle  31 . The heel  12  of the first blade  10  is inserted into and secured by the bow handle  30  with the bow handle  30  located at where strays away from a line L 1  extending from the cutting edge of the first blade  10 .  
      As illustrated in  FIGS. 4 and 5  for the sectional views of the present invention, a pivot axis  25  having at its end provided with a lateral bolt  25 A is disposed vertically on the second blade  20  at where the pivot is preset. An axial bore  14  is disposed on the first blade  10  at where in relation to the pivot axis  25 A to merely enter or leave the lateral bolt  25 A at a given crisscrossing angle. It is to be noted here that the angle is greater than that to open up the scissors to prevent slip. The crisscrossing angle is preferred to such extent when closing upon both of the first and the second blades ( 10 ,  20 ). The lateral bolt  25 A is vertically provided to the extended length of the axial bore  14 . The pivot axis  25  may be integrated with the second blade  20  or inserted through a locking pin provided at where the second blade  20  is pivoted. By means of pivoting to the movable mechanism, the first blade  10  and the second blade  20  are tightly clamped and overlapped to each other to operate as a pair of scissors. Meanwhile, as illustrated in  FIG. 6 , the first blade  10  is disengaged from the second blade  20  by having one hand to hold the bow handle  30  and another hand to hold the ring handle  31  to spread up both blades  10 ,  20  to where the contour of the lateral bolt  25 A and that of the axial bore  14  are matched to respectively pull up and down both blades  10 ,  20 . Both blades  10 ,  20  are now available as two separate kitchen knives. Furthermore, a gap  16  is disposed on the cutting edge of the first blade  10  for a can opener.  
      For a right-handed user as illustrated in  FIG. 7 , he may hold with his right hand the bow handle  30  of the first blade  10  to use the cutting edge  11  as a kitchen knife, or he may turn over the blade  10  to open a can by engaging the gap  16  to the edge of the can. Alternatively as illustrated in  FIG. 8 , a left-handed user may hold the ring handle  31  of the second blade  20  to use the cutting edge  21  as a kitchen knife to skin something.  
      The present invention by providing a pair of scissors that can be split into two kitchen knives saves the trouble of searching for the scissors or the kitchen knife, simplifies the design of having both of the scissors and kitchen knives combined n one piece, and has not yet been made available in the market to comply with the requirements of patent law. Therefore this application for a utility patent is duly filed accordingly.  
      It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.  
      While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
