The blades are designed to flex in the last one-third of their length towards the tip, allowing for much safer thrusting than with conventional wooden wasters or shinai. The blade/tang joint is reinforced by a high tensile steel rod running along the full length of the handle, so removing the handle flex typically associated with plastic training swords. These synthetic-bladed swords also provide an excellent option for theatrical use, being inherently safer than steel or aluminum. The grips are manufactured from a rubber-like thermoplastic elastomer, designed to absorb the impact of strikes and to provide a tight fit on the tangs. These synthetic-bladed swords also provide an excellent option for theatrical use as well.
