    Have just been researching this while looking for stocking stuffers. One alternative I’ve seen is to smash an old sparkplug, the pieces of ceramic are oddly effective at smashing out car windows.

      That was the case when these tools were effective. Has your research shown it still holds true? I would assume the same changes that made the glassbreakers ineffective would do the same for those ceramic shards.
