The mighty Mastiff is a three-and-a-half-foot steel chain with titanium-reinforced 10mm links. It barely flinched under bolt cutters and actually ruined our hacksaw's teeth. The grinder sliced a link in :30, but not without being difficult and dangerous to stabilize on the chains. It's a worthy line of defense, but it's not as portable as the Knog, TiGr, or Blackburn.
