What does a hardened shackle actually do on a padlock, and is it worth the upgrade?
A hardened shackle is made from boron-carbide or hardened steel alloy that resists bolt-cutter attacks and hack-saw attempts far better than standard shackles — a critical feature for outdoor storage, gates, and equipment in Tempe where opportunistic theft is a real concern. The shackle is often the first thing targeted, so cutting corners there defeats the purpose of a quality lock body.
