You are correct that the Bordo 6500 has a 15/15 on the Abus rating system, it seems depending on test, some tests have found faults with the folding locks from Abus. Thanks for pointing this out.
If you are interested in the 15/15 Abus U-lock, the Granit X-Plus, in every review I have read it has not been defeated by bolt cutters (angle grinders, yes). The Granit X-Plus is what I use when I borrow my friends bike in New York, it has a Vds rating, Art foundation score of 3, and a Sold Secure Gold rating
(source).
As for the Stiftung Warentest video, yes, that is primarily what has made me judge the Tigr so harshly.
Here Stiftung Warentest recommends the Abus Sinero ($60) over the Tigr, worth noting is that it is cheaper and lower on the Abus rating (7/15) than my lock I have mentioned previously.
Here is the press release about the Stiftung Warentest test of bicycle locks, out of 37 locks tested only 5 were given a "good" rating and 4 of the 5 were Abus locks, including one of their cheapest U-locks the Abus Sinero. So according to the tests the Abus locks "Especially the three ABUS padlocks Granit X-Plus 54 Granit Plus 51 and 43 Sinero demonstrated resistance to breaking attempts with different tools." I don't believe these locks can be bested by 24" bolt cutters.
My Granit Futura 64 Mini was not included in the test, but it is higher grade than the Sinero which was tested,
here is one review by Road.cc. "The Futura Mini is dinky, but don't think it'll roll over under attack. Ours was barely marked by the big bolt cutters and the persuader -- even with the help of a 2 ton bottle jack -- wasn't able to remove it from its post.". Of course after five minutes of attack the locking mech broke, but it withstood a lot of punishment from bolt cutters.
Here it seems that one of the two distributors in Germany, Manufactum, has decided to stop distributing the TiGr lock because of the test by Stiftung Warentest. They are now contacting customers who have ordered to refund them.
With all that said, after borrowing my friends Granit X-Plus in New York, I think I will get that lock in the future for more high-risk areas. But for now I am happy with my Mini with locking skewers as backup protection.
Every lock can be defeated. If you're worried about someone coming at your bike with those big-assed bolt cutters in the vid, then fine, don't get the skinny TiGr. Maybe even the big TiGr wouldn't assuage your fears.
And that's precisely the point; the OP said explicitly he wanted the lightest lock and didn't need protection from big bolt cutters, so why on Earth you've been carrying on with all this I just cannot understand.
I have two TiGrs and they have changed my riding life with their easy, unobtrusive mounting and lockup flexibility. It's always there when I need it, even when I want to ride light. I've been on several rides where, at the post ride beer stop, I'm the only guy who even has a lock, and guys are asking if I can secure their bike, too. That says a lot to me about other locks, that riders don't even have 'em. I used to struggle to find a way to carry my u-locks, too...for decades...and it never got any better; they're just heavy and awkward....so I get that game, and I'm delighted not to have to worry about it anymore, and that's why I don't mind the TiGr price premium, because it gave me something no other lock could.
The real game is in determining how much security you need while knowing for certain you can never have enough. Like all games, we pay our money and take our chances. Facing that reality, I opted for TiGr, but I get that if lightness, portability, flexibility and ease of use aren't at the top of your list of requirements, then you're gonna wind up gambling on some other lock.
