what chain to get to stop bolt cutter
Standard manual metal saws can cut cable very fast, however armored cable like ABUS Steel-O-Flex series 1000 or 1050 models are a good compromise. A properly hardened* quality security chain, depending on the link gauge, will be either very difficult or impossible to cut with bolt-cutters or manual tools. * many Made in China brands are not consistent in hardening and steel quality.
