Interesting, thanks for the link!
This is the first real-world scenarios I've seen with the TiGr lock, and I had a feeling it sounded too good to be true.
Thank goodness the theft situation in most places isn't as dire as in the video. Where I live, a decent-quality U-lock puts you head and shoulders above the competition, especially when there are adjacent $1,000 bikes locked with cables.
I think I remember reading at one university that about half of bike theft was unlocked bikes, half was bikes with cables, and only 2% of stolen bikes had U-locks. And of those U's, I'm guessing probably most were lower-end ones. I don't know of those stats are correct (or apply everywhere), but it roughly correlates to what I see around me. People in Chicago seem to be trusting U's a lot, even leaving wheels unlocked. And people who ride as their jobs in much worse crime areas than me say that bikes that are locked with high-quality U's or chains don't really get messed with
So I'm not that much more paranoid after seeing the video. I'll keep my hardened chain on the shelf unless I know I'll need to lock overnight or to something of unusual size.

I just read this article earlier today @ the market.
Thanks for the video.

I thought it was interesting they claim to cut (with an angle grinder) through two 18mm hardened steel shackles on a Kryptonite NY-FU Mini in under a minute (other testers have taken twice as long), but can't cut a chain with 10mm hardened steel links before the battery poops out (3+ minutes).
Also, other testers in the past had little trouble compromising lower spec Abus Bordo locks with hand tools, but Mr. Ruzal couldn't. Perhaps Abus has improved this product?

You've just noticed how the skill of the guy who cut matter. I doubt that it is the abus lock that magically improved

Also in this video a kryptonite evolution and spybike tracking system tested (or i would say...defeated)

Also, this author is not an engineer:
...the steel (which replaced iron) in the locks was rounded, becoming smooth, dense, and heavy. Idly biceps-curling the New York Legend chain, I feel a jolt of exertion in my neck. The best locks feature highly dense steel...

Years ago, Bicycling actually employed engineering to their reviews -- for instance, they used machines to measure frame/BB stiffness. Now... they have writers that don't understand the relationship between Fe and steel? I wish I were surprised.

Clamping a u-lock in a bench vice is a good deal less realistic as a theft scenario than duct taping a chain down to hold it still while it is being power cut. In any event, I think a cordless angle grinder is the wrong tool for compromising security chains: cheaper, quieter, just as portable.
Art rating is implying the same thing by giving more stars to chains than ulocks. Why do you think i went for a 19mm hardened chain and the strongest abloy padlock instead of a 18mm kryptonite ulock?
What i meant by magic is the fact that you start from a design and make small improvements from time to time but unless it is magic, you are a genius or lucky you don't make a weak design becoming one day better than strong designs. Art rate the abus bordo xplus 2 stars, good chains are rated 5 stars and cable locks 1 star that must means something.

Kryptonite sez a NY-FU Mini weighs ~2kg (4.5 pounds). A quick 'net check suggests one meter of 19mm security chain weighs around 6.3kg (~14 pounds) and an Abloy 362 adds another 1.4kg (3 pounds).
You're in training for some kind of competitive event?

The grinder blade makes a very large difference though. Thinner blades will cut through a lock much more quickly than thicker ones, with the caveat of wearing out faster and being much more likely to shatter in use.
