WICHITA, Kan. -

They get a lot of requests here at Don Schmid Auto Salvage.

"I've had people come in here for tires, wheels, glass, a little piece of tubing," Aaron Epp said.

But the Does It Work crew wanted something else from Aaron.  We wanted to break a car window and cut a seat belt in order to test the "resqme."

The commercial says the "Resqme tool will help you get out of your car during a vehicle emergency."  The makers say this light-weight tool is supposed to "slice through jammed seat belts with its sharp steel blade and break windows with its spring-loaded spike."  

We bought one online for $10.95.  
That does not include shipping and handling.

"It doesn't seem like it will cut a seat belt or shatter glass," Aaron said.

Pushing his doubts aside, Aaron puts on his safety goggles and gloves, and gets in the driver's seat of a 1993 Mazda 626.  Aaron removes the safety pin and tries to slice the seat belt.  It wasn't as easy as it looked in the demonstration clip.  So, he switched how he was holding it and the direction of the blade.

"That did it," Aaron said.

Now it's time to break some glass.  The instructions say you should use the "Resqme" on the side of the window.  

Initially, Aaron tries hitting the window quickly with the tool.  But, the directions say to apply a steady pressure.  When he does that, the car window shatters in place.

"I can see the tint on it holding it together," Aaron said.

The tint keeps the glass from falling out of the door.  However, it takes little effort to bust through.

"Yep, that's easy," Aaron said.

Aaron says most car windows will react to the "Resqme" like this one did.

"Most cars nowadays have some kind of tint on it, whether it looks clear or not," Aaron said.

We wanted to test the "Resqme" on a newer vehicle with darker tint, so we found a 2004 Chevy Impala.
Aaron takes a seat and starts the test.  He was able to bust through in eight seconds.

Does it work?

"Yes it does," Aaron said.

The key to breaking a window with this device is using steady pressure of at least 12 pounds. The makers suggest attaching it to your keychain or visor-- or loop it around your rearview mirror or headrest.
