Problem

Doors will not open. Windows will not roll down. Then what?

The problem

Doors are very hard or impossible to open against the water. The electric windows die when the wiring is wet. Help takes minutes to arrive. The side window is the way out, and tempered glass breaks from a single point of pressure.

The Safety Hammer

The Safety Hammer needs two inches and one press: the spring fires a tungsten tip into the corner of the glass, and tempered glass does the rest.

  1. 01Press the tip into the corner of the side window.
  2. 02The spring fires. The window shatters.
  3. 03Hook the belt into the slot, pull, and get out.

Thank God for this. I may have not been alive to write this. I can't express my gratitude. Thank you.
Jack, after a 2am roll into a pond.
I used a rescue hammer today in Lorena TX to pull a lady out of a flipped car back SUV window! Soft tap and the window shattered with ease.

Safety Hammer is such a small investment for such an important tool. The peace of mind it brings is priceless.

FAQ

What is the Safety Hammer?

A spring-loaded window breaker with a built-in seatbelt cutter, made to get you out of a car when the doors and windows will not open.

How does it work?

You press the tip against the side window. The housing compresses a spring and the striker fires a focused hit at one point. The other end carries a recessed stainless blade for the belt.

Does it work underwater?

Yes. It is purely mechanical, with no battery or electronics, so water does not stop it.

How long does it last?

There is nothing to run out. The spring resets after every press and the tool sits in its mount until you need it. Test it on the included glass disc when it arrives.

Can children use it?

It does not need strength, only a firm press, so most passengers can use it. Keep it mounted out of a small child's reach while driving.

Is it legal to carry in my car?

Yes. It is sold as a vehicle safety tool. If you travel across borders, check local rules on blades.
