I have been keeping an Ace Hardware 36 inch Bolt Cutter in each truck as a "...master key...", boy was I surprised to find it completely made useless by, you guessed it, cutting the bolt on an actual lock. My understanding was that this was it'd core line of function. So...this has lead me to find a (seemingly) better made set of Bolt Cutters from KREEN with replaceable blades. Since Ace has a 30 day replacement policy and I've had them for years, they will not become a nice door stop but I will acquire and test the KREEN brand and post back here. So....for those who are like minded, I would suggest taking those bolt cutters out and giving them a try and posting here for others. As a reference the model I purchased is ACE Model #2195469, 36 inch Bolt Cutter In the interim be safe.
