Handheld Storage Tube Having an Externally Integrated Firestarter

I claim a handheld storage tube having an externally integrated firestarter comprising:

• a storage tube, being an elongated hollow structure sufficiently sized as to be held within the palm of the user's hand or pocket, being constructed of any rigid material, having threads formed at both ends which correspond and re-movably mate with the threads of a first and second end cap to create an enclosed and accessible dry storage area within said storage tube;
• a sheath, being a second elongated and open ended hollow structure sufficiently sized as to facilitate the insertion and storage of a replaceable ferrocerium rod within said sheath, said sheath being constructed of any flexible or rigid material which is either externally attached lengthwise to said storage tube's curved surface or said sheath being a physical extension or protrusion of said storage tube's curved surface;
• a replaceable ferrocerium rod, being made of any pyrophoric or spark generating material, being re-movably linked to the first end cap by any means that allow it to swivel, rotate, flex, or move independently of said first end cap;
• a first end cap, having threads that correspond with and re-movably mate with the first end of said storage tube, and being linked to said ferrocerium rod by any means that allow said first end cap to swivel, rotate, flex, or move independently of said ferrocerium rod;
• a second end cap, having threads that correspond with and re-movably mate with the second end of said storage tube, having a flat mounting tab extending perpendicularly from the diameter of the flat end surface of said second end cap, having a void milled through the center of said mounting tab's face whereas the void is dimensioned as to preserve enough surface area of said mounting tab's face as to accommodate the mounting of a replaceable scraper to the remaining surface area of said mounting tab's face along one edge of said void with a portion of said scraper's edge protruding into said void, while also accommodating the insertion of said ferrocerium rod through said void;
• a replaceable scraper, being flat and elongated with a screw hole near each end, being made from carbon steel or any other material having similar physical characteristics which allow it to generate sparks when scraped along the surface of said ferrocerium rod, and being re-movably attached by the use of screws to said mounting tab of said second end cap;
• two elastomeric gaskets, being re-movably placed between the threads of said storage tube and each end cap to create a waterproof seal.
