That was indeed the thinking behind it 🙁nod):
Why they considered such a high end lock to be primarily at high risk from heavy hammer and impact attacks only, and to pay little attention to drill, saw or cutter attacks beats me. Even more so when you considered the price on them- Cruisers and Battleships also- very expensive padlocks. When you consider the incredibly tough alloys used at the time by the likes of Ingersoll, Abloy, Master etc and basically most others making locks in the top categories, Chubb’s choice of spongebob iron seemed a little odd. But, in their defence, we are talking a company that for a time led the world for safes, research, testing and most importantly- the development of barrier materials. So, with that in mind I guess there must have been a lot more to it than that 🙁think):
