The purpose of this product is to cut the foam and plastic easier than to the other materials. It is different from other cutters because it has a nichrome wire that will cut neatly and nicely than other materials. It is also has a special taser where we can use it for self-defense and a light that we can use in the dark place or even when we are cutting foams and plastic. We don't have to worry if its brownout because this product also has a solar power bank.
