  1. Make an alloy with a stronger metal (i.e. tungsten).


  2. Heating,folding, on creating alloys are all good answers.

    However, how you heat is important. There is an old technique called "coking".Coke, is a form coal takes in the burning process ( the process of coking would take considerably more space and time than available)

      The coke process allows the steel to take on more carbon, and by folding this extra carbon into the steel it creates a stronger steel that has a slight flex quality to it.. I.E. not brittle.

      There is also a folding technique used in knife making that produces Damascus steel, alternating band of two separate metals sharing a minimal bond. The result is a remarkable mix of strength and flexibility.

  3. If you get it red hot and dip it in water it will harden, but become more brittle. You can see an example of this when you take a very hot pan off the stove and stick it in the sink and run cold water over it. Sometimes it will even break the pan.

  4. fold it

  5. Heat the steel until it is completely red hot. Then, quickly but carefully submerge it into oil. Let it soak in the oil until it is cool to the touch. There are special oils for this but used motor oil will work fine.

  6. get it very hot and then cool it quickly.  this is called tempering.  perhaps you should look up "tempering" on wikipedia for better instructions.

  7. Start by learning English..

  8. Either work it or melt it down and reformulate it!
