Building a furnace and casting a beautiful copper knife is our latest video. In this video we made a knife from the copper that we created. It took us a long time to collect the copper.
We did a lot of experiments to melt copper to mold a copper knife, so many times we failed. We succeeded successfully and created a pretty sure and beautiful knife.
Initially we collected the required amount of copper, we built a new oven with better wind system, we used coal ash to make a metal coke when melting. We use stone knives to make molds on sand.
We will continue to do some necessary stuff when we collect the required amount of copper. We will continue to make the next video on primitive technology and wild survival skills.
