By far the easiest and cleanest way is to use the method shown on the Earl's website. They use a large sharp masonry chisel, a 5 lbs maul and a small flat block of brass.

One good hit is all it takes to cleanly and instantly cut any braided line.

I was shocked when I watched how easy it is to do on their video. They cut all of their lines this way. It leaves the hose clean and the ends perfectly formed with no taping required.

A sharp chisel and a block of wood. Works very well. Clean cut and no burrs.
