After watching several failed attempts to cut this Pewag 1/2" chain with 42" bolt croppers on YouTube, I was sold. The only time I've seen it cut is in a vice with an angle grinder, which still took two cuts taking over a minute in ideal conditions. I bought 4' with an Abus 37RK/70 padlock, which I strap across my body when biking. It all weighs just under 15lbs, but I don't mind the weight.
