The spring loaded baton expands from 8.5 inches to over 20 inches with the touch of a button. There is a safety feature that prevents it from opening accidentally which is a good thing because it comes out with a powerful 30 pounds of pressure. That could cause a lot of damage to an attacker that gets too close!
Expandable spring baton automatically extends with a simple squeeze.
When quickness matters, nothing beats the automatic extension of this metal baton.
