Description:
BACKGROUND OF INVENTION 
       [0001]    1. Field of Invention 
         [0002]    The present invention relates to a tool and, more particularly, to a sheath for at least one tip of a tool. 
         [0003]    2. Related Prior Art 
         [0004]    There are tools each of which includes at least one tip. For example, a claw hammer includes two claws each including a tip. A chisel includes a tip. An ice pick includes a tip. A mattock (or “pickaxe”) includes two tips. A crowbar includes two claws each including a tip. Such tips are sharp and might cut users or objects such as vehicles and furniture. Such tips are brittle and might get damaged when they are brought into contact with hard objects such as rocks. 
         [0005]    Therefore, the present invention is intended to obviate or at least alleviate the problems encountered in prior art. 
       SUMMARY OF INVENTION 
       [0006]    It is the primary objective of the present invention to provide a tool with a sheath. 
         [0007]    To achieve the foregoing objective, the sheath includes at least one hollow body. The hollow body includes a space with an open end and a closed end opposite to the open end so that a tip of a tool can be inserted in the space through the open end. 
         [0008]    In another aspect, the sheath includes two hollow bodies. Each of the hollow bodies includes a space with an open end and a closed end opposite to the open end so that a tip of a tool can be inserted in the space through the open end. 
         [0009]    Other objectives, advantages and features of the present invention will be apparent from the following description referring to the attached drawings.

     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0019]    Referring to  FIG. 1 , there is shown a sheath  100  according to a first embodiment of the present invention. The sheath  100  includes a single hollow body  10 . The hollow body  10  is made of a flexible material for absorbing shocks. The hollow body  10  is preferably in the form of a rectangular cone, i.e., it includes two lateral flat members extending to a flat upper member from a flat lower member. The hollow body  10  includes a space  11  defined therein. The space  11  includes an open end  12  and a closed end  13 . The space  11  is tapered toward the closed end  13 , and so is the hollow body  10 . The hollow body  10  may alternatively be in the form of a circular or oval cone. 
         [0020]    Referring to  FIGS. 2 and 3 , there is shown a multi-purposed hammer  91  that includes two claws and a horn  911  extending from one of the claws. The horn  911  includes a tip. The tip of the horn  911  is inserted in the space  11  through the open end  12  of the space  11 . The tip of the horn  911  is wrapped by the closed end  13  of the space  11 . The tip of the horn  911  is tightly placed in the space  11  since the space  11  is tapered toward the closed end  13 . 
         [0021]    Referring to  FIG. 4 , there is shown a sheath  200  according to a second embodiment of the present invention. The sheath  200  includes a single hollow body  20 . The hollow body  20  is in the form of a rectangular cone, i.e., it includes two lateral flat members extending to a flat upper member from a flat lower member. The hollow body  20  includes a space  21 , two slits  24  and two slits  25 . The space  21  includes an open end  22  and a closed end  23 . The space  21  is tapered toward the closed end  23 , and so is the hollow body  20 . The hollow body  20  further includes two slits  24  and two slits  25 . The slits  24  are respectively defined in the upper and lower flat portions thereof near the open end  22 . The slits  25  are defined in the upper and lower flat portions thereof near the closed end  23 . The slits  24  and  25  increase the flexibility of the hollow body  20 . 
         [0022]    Referring to  FIG. 5 , there is shown a sheath  300  according to a third embodiment of the present invention. The sheath  300  includes two hollow bodies  30  joined together by a connective portion  40 . The hollow bodies  30  are in the form of a rectangular cone. That is, each hollow body  30  includes two lateral flat members extending to a flat upper member from a flat lower member. Each hollow body  30  includes a space  31 , two slits  34  and two slits  35 . The space  31  includes an open end  32  and a closed end  33 . The space  31  is tapered toward the closed end  33 , and so is each hollow body  30 . The slits  34  are respectively defined in the upper and lower flat portions thereof near the open end  32 . The slits  35  are defined in the upper and lower flat portions thereof near the closed end  33 . The slits  34  and  35  increase the flexibility of each hollow body  30 . 
         [0023]    The connective portion  40  preferably connects the open end  32  of each hollow body  30  to the open end  32  of the other hollow body  30 . The connective portion  40  may alternatively connect the closed end  33  of a hollow body  30  to the closed end  33  of the other hollow body  30 . 
         [0024]    Referring to  FIGS. 6 through 8 , there is shown a claw hammer  92  that includes two claws  921 . Each claw  921  includes a tip. The tip of each claw  921  is inserted in the space  31  of a respective hollow body  30  through the open end  32  of the space  31 . The tip of each claw  921  is wrapped by the closed end  33  of the space  31  of the respective hollow body  30 . The tip of each claw  921  is tightly placed in the space  31  of the respective hollow body  30  since the space  31  is tapered toward the closed end  33 . The slits  34  and  35  increase the flexibility of each hollow body  30  so that the tip of each claw  921  can easily be inserted in the space  31  of the respective hollow body  30  even if the width of each claw  921  is a little larger than that of the space  31  of the respective hollow body  30  as shown in  FIG. 7 . 
         [0025]    The present invention has been described via the detailed illustration of the embodiments. Those skilled in the art can derive variations from the embodiments without departing from the scope of the present invention. Therefore, the embodiments shall not limit the scope of the present invention defined in the claims.
