Query: cuttable

my wife had her bike stolen in daytime at a busy spot. the thief cut through the cable, looks like with a hacksaw. this is not a good lock.also, if you check out the manufacturer's website, they have a guarantee (if you send in a slew of paperwork on purchase and then after you file your police report). However, this lock is not covered by the guarantee. Kind of strange they sell a lock they won't back up.
