If you have the time, a good quality hacksaw will do the job. You may need to make two cuts.
As the shackle is sub 12mm (I think), a very long pair of bolt cutters should also do it - you may be able to hire a pair from nearby.
My god those two blokes in the video talk. STOP TALKING AND JUST DO IT.
