Supposedly a hacksaw. My opinion is that you're more likely to get success
(and much more quickly) by reusing the old olive than hacking the pipe
around. You can get proper olive removers, but they're expensive.

AFAIK you can undo and tighten up compression fittings as many times
as you like.

I think I may have misread the original question. Obviously, you reuse the
olive if just retightening an old joint. I was thinking that the entire
valve had been replaced. (i.e. replacing handwheel with TRV).

You will never get one off intact or without damaging the pipe
Occasionally they leak when reconnected
Just needs a bit of PTFE tape wrapped round them to fix the problem.

Talking ******** too. Admittedly rarely get one off intact (except when
its been on stainless steel pipe) but not too hard to remove without any
damage to the pipe. Done it many times.

Dremel type device, slim cutting disk and cut a partial thickness groove in
it (I usually do it on the diagonal). When deep enough (but obviously not
full thickness if you want to avoid damage to the pipe) insert the tip of a
good screwdriver in the slot and twist. This will then snap the olive.

The most important part is to make your cut as clean as possible with
vertical sides so that the screwdriver tip gets a good purchase.

I do exactly that, but with a junior hacksaw.
