Safe-Cracking Techniques by Country

One of the things we've learnt over the couple of days is that, generally, different countries have different techniques at safe-cracking.  On our first day here, during a tour of the Weizmann Institute, the woman who was leading the tour talked a little about previous safe-cracking competitions that were held here.  She mentioned in particular the difference between the Israeli teams and the British team.  Apparently, the Israeli teams would try absolutely anything to try and crack a safe (including banging, prodding, and ripping violently) The British team, on the other hand, would be much more "gentle" and instead of using their hands, they would debate about what could possibly be the answer.  This team was very intelligent, but invariably, the safe would not end up being cracked.  The Israelis, though they might not necessarily understand all the physics behind the safe, blind trial and error sometimes yielded results.  The woman's lesson from this was to try everything, even if it may not make sense to you.  As it turns out, we witnessed many of the safe cracking techniques while we monitored our own safe and it pretty much went with the woman's description of the various teams.  One of the first questions of the Israeli teams that wanted to crack our safe was can we use the "plunger" to push the buzzer out? Or, "can we shake/pick up/move the safe?"  As for the British team, they would think for ten minutes and then act, as expected.  They were pretty brilliant though, I have to admit. I can't really evaluate our way of cracking safes...maybe because we were so close to the situation.  I'm sure though, that another country would be able to point out the "Canadian way" of cracking safes.
