The ASP Protector P21 Clip-On Baton is the perfect choice for self-defense. With a extended length of 21", 8 1/4" collapsed, this baton is capable of delivering serious blows to an attacker. The black chrome plated 4130 striking surface is incredibly tough and will not back down in a fight. The 7075-T6 aluminum middle shaft and handle are forged to shape and precision machined to provide a comfortable and secure grip. The cross check knurling with spiral micro grooves provides superior grip even in the most challenging situations. The baton can be expanded by sharply flicking it straight up and down, and retracted by striking the tip downward on a hard surface. This baton comes packaged for easy storage and transport.
