The Kryptonite model was done in <30 seconds.
Funny thing, I may be over simplifying this, but if you watch the vid of them trying to cut the chain on their products, there is one critical difference. The links they use appear to be so large that the cutters arms can't close far enough to get the leverage needed to cut through. Simple physics. That's a pretty good idea along with the hardened materials etc. Of course the bolt cutter company would just need to redesign the cutters to get better compression leverage and the game starts over.
I suppose it'd be easier for a thief to just unbolt the rear wheel if they couldn't cut the chain. LOL Imagine coming back to where your bike was parked only to find your rear wheel laying there on the ground. Better loop it through the swingarm too.
