- Q:I have one and wonder how much force this can take since it does seem like you can bend it(Sure it's impossible with hands), but I don't want to try that cause i don't want to break it. Many people say that it's really hard and can handle a hammer smash? is that true and can it even make it through more force. Cause steel is harder than iron and iron is pretty hard... So how much can i trust this locks security, i mean if i put at at a door would some thiefes be able to break it, if they had the right tools??
- any pair of larger bolt cutters would whack right thru that lock brother. use it, but put a backup lock on somewhere else too. thx for the pic!
