A bag-shaped sword blade section having a throttled opening formed of a sealing and elastic material such as rubber is fitted onto and closely attached to a tip end of a cylindrical-shaped grip formed of a hard material such as wood, a hard rubber, plastics and metals. A gas such as air is filled in the sword blade section to define a cavity. Accordingly, a soft sword is made uniform in quality, and undergoes less degradation in quality even after an extended use.
