The shackle is the part that gets cut, so it is the part to read · review
A light aluminum-bodied padlock with a 6.9 mm (0.27 in) hardened shackle and a high shackle 22.3 mm (0.88 in) wide. BURG-WÄCHTER states double shackle locking and two keys.
The conclusion A light, non-seizing lock for a low-value gate. Do not put it on anything a cropper would be worth bringing for.
Padlocks are chosen on price and defeated on shackle diameter. That single number decides which tool works, and everything else on a listing is secondary.
It means bolt croppers. A shackle of this diameter is within reach of a tool somebody could carry under a coat, which places this lock squarely in the category of gates, barriers, lockers and anything whose contents are not worth a serious attempt.
That is not a criticism — most padlocks are used exactly there — but it should be said before the purchase rather than after.
The body is aluminum, so it does not rust into a solid lump over a winter on an outdoor gate. Seizing is how most padlocks actually end, and a lock that still opens in February is worth more than one that was harder to cut in August and is now unusable.
The high shackle, 22.3 mm (0.88 in) wide, reaches through thick hasps and chain links that a standard shackle will not.
The shackle is retained on both legs. Locks retained on one side can be defeated by attacking that side; this one requires both to fail. Few listings at this price mention it.
A garden gate, a barrier, a locker — anywhere the lock is a formality rather than a defense.

For a garden gate, a barrier or a locker, yes. For anything a bolt cropper would be brought for — a trailer, a generator, a shed with tools in it — no. Shackle diameter is the number that decides which tools work on a padlock, and 6.9 mm (0.27 in) yields to a cropper most people could carry.
Weight and corrosion. An aluminum-bodied lock on an outdoor gate does not seize solid over a winter, which is how most padlocks actually die. It is softer than hardened steel, and this is a trade rather than a free improvement.
The shackle is retained on both legs rather than one. It matters because a lock retained on one side can be defeated by attacking that side alone; retaining both means both have to fail. It is a genuine specification, unlike most of what appears on padlock listings.

| FJM SPSA80-CR-KA D-style high security padlock, 80 mm, keyed alike | $37 | A freely rotating hardened steel shackle with heel-and-toe locking, in a D-shaped body stated to grant very little access for bolt cutters or saws. 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 |
