Chopping without flopping

Todd Just so there's no need to start another thread...
What's best for chopping down bars? Hacksaw or pipe cutter?
I have some risers I'd like to shorten but don't fancy bodging them up again like the last ones I cut into.
Anyone used a pipe cutter?
Anyone have one I could borrow swiftly?
Or is it time to get out the hacksaw?
cheers.

hacksaw is fine, however most people can not cut a straight line in wood for toffy let alown in metal (same technique I know but you have to pay more attention). So if you are not comfident use soem pipe cutters.
