Been seeing a lot of videos about them breaking glasses in an instant, but i’m clueless to this sorcery. The same glasses take say a conventional hammers/crowbars/screwdrivers multiple tries to break. There’s no source telling how it works and i’ve personally never seen this thing in real life. Why do these hammers have such a small tip and how does it breaks glasses with ust a mild pressure on the window? I get the seatbelt cutting part, but the hammer part is a bit baffling.
Is “f=ma” the right answer to this concept?
Some unusual designs they’re coming in now (tubes) are beyond my comprehension.

A hammer spreads the impact over a wide area, which can be more easily absorbed by the glass. A safety hammer concentrates the impact at an extremely tiny point. It’s also quite hard, most likely harder than your screwdriver.
For example, put a small thin piece of hardened steel over glass, hit the metal with that safety hammer, and it won’t break. That’s because the metal spread the impact over a larger area on the glass.
