Mine came from a pound shop, used it about ten times so far.Turn the screw in slowly and carefully without rushing it and trying to cut to deep every turn, and you get a perfectly neat cut with no burring, internal or external that needs filing.
A hacksaw seems like an awful lot of effort to me. Even if you do trust yourself to cut it square, a hacksaw is a very long winded way of doing it if you need to take the fork out of the frame or keep swarf and cuttings from going everywhere as well.
"using the pipe cutter method, can you perform the op without taking the fork out of the frame and all the associated disassemblage? (i'm wuite lazy…) " yes, just make sure you're cutting where you need to.
