Cardboard and Duct Tape Kunai

I have always enjoyed making paper or cardboard weapons out of anything I can find. This is one of my favorites.


               Materials-
         
               2 cardboard flaps approximately 5x10in.
               1 duct tape roll (you wont need it all)
               1 box cutter
               1 ruler
               pen or pencil
          

Draw a triangle with 4 in. as the base and 2 slanted sides 6 in. long. Then draw a line down the middle. Do this twice also cut out two rectangles with 4 in, as height and .5 in as width.

Make a shallow incision along the line drawn in step two in both triangles then fold to make a raised triangle.

Take the two triangles and duct tape them together then take each rectangle and tape it to the inside of each triangle,with the two points sticking out of the end tape them together. Then tape all the cardboard so no more of its color shows and Your Finished! !!
