"Don't be a wimp and wear goggles." Atma pulled out an ingot and started on making a spear head, after beating it a few times he drenched it and then put it back into the forge to heat up again. The spear's head was the easiest part so he could finish it pretty fast. The harder part would be flattening an ingot so he could beat it into a tube. The part Atma loathed would be making the parts for the switch that would extend the spear to full length. The little intricacies involved would annoy him to no end. He grabbed a larger hammer and pulled out another ingot to beat it flat, sparks were flying everywhere with each strike of the hammer. The ingot went back in without being drenched and a fresh ingot was pulled out to beat flat as well. "The reason you drench and heat-treat metal is that the rapid heating and cooling helps to make the blade stronger, so it can cut and stab soft targets easily. You don't ever drench kunai though because drenching and heat-treating a blade also makes it more brittle. So with this spear I can't go stabbing walls with out ruining the spear. I can stab walls with the kunai though no problem." Atma finished speaking as he started to flatten the next ingot as he didn't want sparks to fly down his throat.
