If you need bolt cutters to cut steel
bolts and chain fine. If you are looking for something to cut rigging
you need rigging
cutters (and big 0nes). Rigging cutters have a semicircular hole in one jaw so the rigging wire fits into the hole and the wire is sheared and not cut as with bolt cutters.
i have a pair about 2 1/2 -3 feet long and store them in a locker handles down cutters up. i spray the cutters with oil
and put a zip lock bag over them and tape the bag closed around the cutter head
