Watching the nut splitter video on the Abus Brodo lock, I noticed the coating surrounding the pin on the lock links were pre-removed. Without removing the coating, it would not have been possible to place the nut splitter against the pin to spli it. The removal of the coating was not highlighted in the video and we do not know what was used and how long it took to remove. I presume it is probably a tedious process - one which most bike thieves would not want to undertake. Hence, I still prefer the Brodo lock over others.
