Watch This Blacksmith Turn Old Batteries Into Beautiful Knives

Shurap is a talented YouTuber and also a blacksmith by profession who has found a way to recycle old batteries. He converts these old batteries into beautiful knives. The Damascus-steel knife uses a Maglite flashlight for its handle.

It is advised not to try this yourself and for those of you who choose to ignore that advice, slap on a pair of rubber gloves before you try to pry out the metal in the batteries as it contains highly-caustic materials that can harm the skin in case of direct contact.

You can watch the whole process in the video below:
