Just a reminder: eveyryone should carry a hammer to break car windows

59. You should be able to manage.

Pick one up at the home store and give it a try. There are different settings for how much of a mark you want to make when using it as a punch. Press it against the steel display frame in the store.

I use them for marking tile for drilling. The punch makes a small chip in ceramic tile or natural stone. The chip makes drilling easier as the drill bit doesn't travel.

Though I don't see why one would use the punch on the windshield unless it is a last resort. The windshield is laminated with plastic so it would take a lot of force to get out even after the glass shatters.

All the other car windows will collapse in to mostly harmless tiny chunks.

Tempered glass is REALLY strong. But it is susceptible to concentrated force of other hard surfaces. That's why the center punch works.

More than a few people have learned the hard way setting expensive tempered shower doors down on tile. My neighbor moved a shower door we were installing in her bath. We had it set on towels but she moved it to clean. She set it on the tile and a piece of the corner popped off. She's very lucky it didn't explode in her hand.
