The shackle is the part that gets cut, so it is the part to read · review
A monoblock cast-iron padlock: the body encloses the shackle so that very little of it is exposed. KOTARBAU states a chrome-plated hardened steel bolt in a solid cast body.
The conclusion The shrouded shackle is worth more than every other feature in this hub. Measure the hasp before ordering.
The other padlocks in this hub leave their shackle exposed and are defeated the same way: jaws either side of the shackle, and squeeze. This one does not offer anywhere to put them.
A padlock is attacked at its shackle, and a bolt cropper needs to get on both sides of it. A monoblock body wraps the shackle so that only a few millimeters are visible, and those few millimeters are inside a cast-iron shoulder. There is no combination of hardening, keyway or brand name that changes a lock’s resistance as much as removing the target does.
If you buy one padlock on this site for something that matters, buy a shrouded one.
Clearance. A shrouded lock has almost no gap under the shackle, so it will not pass through a thick hasp, a heavy chain link or an eye bolt of any size. Measure what the lock has to go through first — this is the commonest reason a shrouded padlock is returned.
Cast iron: resistant to cutting and abrasion, more brittle than forged steel under a heavy hammer. KOTARBAU publishes no security grade, so nothing further is claimed here.
A shed, a store, a gate — anywhere the lock is protecting something worth carrying away.

That the body is a single casting which wraps around the shackle, leaving only a few millimeters exposed. Bolt croppers need jaws either side of the steel, and a shrouded shackle simply does not give them anywhere to sit. It is the most effective change available in a padlock.
Clearance. A shrouded lock has almost no gap, so it will not pass through a thick hasp or a big chain link. Measure what it has to go through before ordering, because a lock that does not fit is a lock that gets replaced with a worse one.
Both. It resists cutting and abrasion well, and it is more brittle than forged steel under a heavy hammer blow. KOTARBAU publishes no grade — the ABUS Titalium locks here state ABUS level 5 or 6 — so this is the general property of the material rather than a claim about this lock.

Heel-and-toe means the shackle is secured at both ends, so cutting one side does not open the lock — both legs must be cut. It is the strongest shackle arrangement on this shelf |
