The slow match or punk rope to fit in the brass cylinder may be made of candle wick or coach wick purchased at the hardware store; such wick is about three-eighths of an inch in diameter. Scout Commissioner John H. Chase of Youngstown, Ohio, suggests that the rope may be made from the wastes of a machine shop or a garage; but one of the best woodsmen I know is Mr. Frederick K. Vreeland, and he uses the apparatus shown by Fig. 34, which is made of the yellow fuse rope, or punk rope, which may be purchased at cigar stores. He fastens a cork in one end of the rope by a wire, he pulls the other end of the rope through the end of the brass cartridge shell which has been filed off for that purpose. The end of the fuse rope must be charred, so as to catch the spark. To get the spark he takes the back of the blade of his knife (Fig. 35), and strikes the bit of flint as you would with flint and steel, holding the charred end of the punk against the flint, as shown by the diagram (Fig. 29). Loose cotton and various vegetable fibers twisted into a rope soaked in water and gunpowder will make good punk when dry.

To Get The Spark

Place the charred end of the rope on the flint, the charred portion about one thirty-second of an inch back of the edge of the flint where the latter is to be struck by the steel; hold the punk in place with the thumb of the left hand, as in the diagram (Fig. 29). Hold the knife about six inches above at an angle of about forty-five degrees from the flint, turn your knife so that the edge of the back of the blade will strike, then come down at an angle about thirty-five degrees with a sharp scraping blow. This should send the spark into the punk at the first or second blow. Now blow the punk until it is all aglow and you are ready to set your tinder afire. Push the punk into the middle of a handful of tinder and blow it until it is aflame, and the deed is done!

All these pocket contrivances for striking fire were formerly known as "striker-lights" or "chucknucks."
