I use an ABUS D-lock and one of these, the cable is about 3/4″ thick
no idea how solid they are, but they have a silver rating.
Bronze means “Can be cut with scissors”, Silver means “The scissors have to be quite sharp” All these test standards are nothing but a scam unfortunately, lots of ridiculous attacks “We attacked the chain with a combination of harsh language and baking soda for 5 minutes and it didn’t break!” and nonrepeatable results “Boltcropper proof until an independant tester tries it and cuts it in 10 seconds”.
There are afaik no cable locks that aren’t faster to cut with cablecutters, than they are to unlock with the key. But none of the testing systems use proper cable cutters.
The Abus thing seems to be less terrible than most but I’m never sure if it’s actually secure or just designed to pass tests.
