Not til next Monday (23rd Feb), mind!
Yeah, yeah, so what, its a hammer, but for less than three and a half quid its a bit of peace of mind - nasty to think of, but what if you're unconcious in your car following an accident and the kids cant get out of the back because you're in the way? This little hammer can live in the seat back pocket and instantly smash a side window for anyone in the back to get out (or you too, if your door is caved in!).
One of those things you want to own and never use, but imagine wanting to use but not own!
