Comments about Abus Abus Nautilus Combination Padlocks:
When new the lock works well. As the lock ages it starts to have problems. In its second year the internal mechanism starts to jam prevent the lock from locking smoothly.

Other such padlock mfgr's see no need for a special (lose-able) tool in order to change the lock's combination. Simply rotating the opened lock's collar 90 degrees and pressing it down allows most locks of these kind to have their combination changed (and prevents situations where the 'special tool' is not susceptable to loss).
