A great lock puller to use with your pro bar. The Adze Rex stores nicely in a pocket and works on a wide range of locks. I am proud to see that this firefighter level modification was supported by Fire Hooks Unlimited and is now offered. Modifying Tools (Adze Rex background) http://community.fireengineering.com/profiles/blog/show?id=1219672%3ABlogPost%3A575402 The tools features the same lock-pulling head as the REX Tool, but without the pry bar. Carry in your pocket, and when needed, apply to a lock cylinder and pry with your PRO-BAR's Adz. The Lil-Rex comes with a leather carry case and entry keys.
