Following the creation of the A-Baton, the Founder designed the "handguard", a portable self-defence implement.

Combining the functionality of other well-known portable implements like the kubotan and knuckle duster/ brass knuckle, it acts as a force-multiplier to supplement the user's basic self-defence skills.

For self-defence training, the handguard's design and user concepts provides an excellent bridge to employing common everyday items such as the pen and house keys into implements to escape a violent altercation.
