Nickle plated hardened above 5mm link steel chain requires cutters with 4? foot arms and you usually have to put one arm on the ground to get enough leverage.
Hard to hide cutters that big under a sweater. I'll probably get a new lock but @ least I don't have a Krypto.
Also if using a padlock- if it has key or ident #, write down and file off. A key can be ordered to replace or to steal I've been told.
Oh, my lock is 40mm with a 5mm hardened bolt so it's gonna be a tough cut too. I'll probably go 8mm hardened chain and lock soon. Cost maybe $20-$24.
