The kevlar fibers don't really work in practice. Turns out you can just use a pair of shears or a boltcutter. Examples: https://www.youtube.com/watch?v=j7ah3R

  It is not this. I don't remember where I found it but only the sheif has Kevlar fibers, there is what I think is a hardened steel chain in the middle. The loose Kevlar fibers don't offer any strength, instead, they make a mess if you try to cut through the sheif. You can probably cut through the sheif and Kevlar with shears to reveal the chain and then use your angle grinder but it will slow you down, especially if everything is entangled.

  https://altorlocks.com/products/saf-lock https://altorlocks.com/products/saf-lock sounds more like what the parent was referring to. It's a good example of clearly addressing a specific threat model: it doesn't try to be impossible to cut (although the marketing material says otherwise...). Instead it's just so thick that a 5" angle grinder can't reach all the way through it in a single cut, and the coating material is specifically designed to be slow to cut through so that it takes a long time and requires multiple batteries. Of course, it still has the obvious problem that the thing you're locking it onto is probably a lot easier to cut.

    Holy cow, 6.2KG!! That’s almost as much as a good bike weighs, and enough weight to seriously feel it lugging that around. I guess if you really have to leave your bike locked in public for long periods of time it could be worth it, but wow, that would not be a nice or convenient thing to lug around.
