Still waiting for someone to invent nobendium
Peple often mix Bordo with Bordo Granit X-plus. The later one is about twice the price and a lot stronger. Both the lock cylinder, rivets and steel plates are a lot stronger.
Though, leaving the lock low enough so that ground can be used as a leverage is always a bad idea.
Every lock cylinder can be picked. With enough knowledge, proper tools and enough time. Not many thieves have those. Abus Granit X-plus series (chains, Bordo model and U-locks) have good cylinder and good locking mechanism (the part that keeps the ends of chain/lock together to the cylinder) that is hard enough to pick that the preferred mode of beating them is cutting/breaking.
Every steel rod can be cut and/or broken - also just the matter of tools and time (and noise).
Like someone said a few posts above, as soon as the bike is better secured that the next one, it is quite safe.
