When I replaced my bathroom 3 years ago I replaced all the piping to
the bath, sink and shower with polypipe. I looked at a couple of
proper pipe cutters but decided the cost was not worth it for a
single job. I used a junior hacksaw and then cleaned up the cut ends
with a Stanley knife (making sure no plastic swarf was left inside
the pipe of course). The entire bathroom has been 100% watertight
since I did the job!

You'd make a good mate for Drivel then!

Whatever else you may do to plastic pipe, *don't* cut it with a
hacksaw. In the absence of a proper cutter, a decent pair of by-pass
(*not* anvil type) garden secateurs makes a good substitute.

The slightest roughness or burr on the outside will bugger up the
O-ring of a push-fit fitting - which will then leak like a sieve.
[Not quite so critical if you're using compression fittings].

I agree with what you say about the roughness - which is why, having cut the
pipe to the required length with a hacksaw, I then cut off a further 1-2mm
of the rough-cut end with a Stanley knife which completely removes all
roughness or burr from the end of the pipe.
