Saber, light sword, laser or lighter is a strong weapon. The knife of light saber is an odorless form that does not radiate heat and expands energy until it contacts the solid. The power of the blade is so great that it can cut through everything. The speed depends on the destination and the object. One of the most important injuries of a light saber is that it will not bleed even if the limbs are cut. This is because the power of the blade causes burns and so the cuts are caused by cutting.
