This is the cheapest one I see, but there are nicer ones. Basically a large cable cutter

Use this, and forget about tape, grinding, cutting, cleaning whatever. This will cut the hose clean as a lazer, and it has the added benefit of slightly reducing the end from the radial compression. making it easy to put the fittings on. literally, one second and the cleanest cut you can get. Even works on double braid.
