Why is it that the white ceramic part of a Spark plug is so good at breaking toughened glass ?

Good question.  All I know is that it is popular to break the ceramic out of the spark plug and throw them through car windows...f$^%'in punks.

I'd imagine it was a combination of the shape giving it an impact over a very small, focused area, and the fact that the ceramic material is extremely hard.

What ever the spark plug insulator is made of it breaks glass real easy. Ghetto thieves EDC a peice in there pocket.

Somehow, I think I'd rather be carrying a manufactured tool so as to have someone to blame when it doesn't work right...

When i got my Swiss rescue tool i went to picknpull auto wrecker to try it out on cracked windows and seat belts we all so did the spark plug thing it worked well. We took a spark insulator and taped on the windows and we thew the insulator at the windows both ways it shattered the safety glass.

Id rather you used something my daughter made....hopefully I would have enough time to reach into your burning, sinking vehicle to relieve you of your knives and MT's before it was too late.

Yer after the wrong guy there.

Yeah but I think I may be even cheaper so your crap may be better than my crap.

The insulator from a spark plug is in fact porcelain,

 interestingly the same material used in teeth Veneers,if that's the case in an emergency one could just bang ones face off the window

It makes perfect sense that a rescue tool is a permanent feature of your keychain and no bigger than say, a key. I wish instead of this DIY one I could just buy one but I want it to be no bigger than this one. Does anyone know of a commercial version this size?

Well not exactly this size, a bit bigger. I have a "resQme" in my car. I live between two rivers, every so often someone drives into one of them, so I play it safe. I prefer to gave a spring loaded centre punch. Who knows if you'll have enough space/strength/time to swing something with enough force.
