Sharpen the knife, then stab it into the surface of the bamboo, and press hard to make it go deep into the bamboo. Next, he used the hammer to lightly tap the hole of the knife. He controlled the strength and made the knife go a certain depth. Then, he heated the electric iron and placed it into the hole. He let the iron enlarge the hole.
