  • HAVE A GO ITS IS NOT HARD TO DO IT TAKE A BIT OF ENERGY IT A THING THAT THE SWORD MAKER OF JAPAN DO TO START THERE FORGES SO I BEEN TOLD THE TRICK IS SOFT STEEL NOT COLD DRAWN HAVE A GO ANY ONE GLENN MOON HERE

  • * friction between the molecules *

  • @rittersteel not friction,heat dissipation.

  • Go Moony!

  • It is friction. The work energy of the hammer is not being carried away by convection fast enough to keep the metal less than "red hot." The plastic deformation of the metal, moving the metallic grains relative to one other, causes intergranular friction and the shifting/breaking of atomic bonds. Potential energy in the form of linear elastic deformation is a very small portion of the energy of deformation in this case.

  • It's not friction. You could call it compression, but really it's just energy transfer. Kinetic to potential, released as light and heat.

  • But good grief, take that cutoff hardy out of the hole before you lose a couple fingers!

  • Awesome! I've heard of this, but I was always kind of skeptical. I doubt no more!

  • glenn moons a beast

  • That's so damn cool.
