I've done a number of joints with a Stanley knife when my cutter went
awol. It's fine as long as you are careful. Whilst a cutter is the right
tool, if you are doing just a couple of joints I'd probably just do that

I used a copper pipe cutter to put a groove in the plastic pipe then used
the SK, as this gives a followable mark to ensure a square end and also
slightly rounds off the outside so that it goes in to the O-ring seal with
no risk of damage.

Why faff about? Just go all the way through with the copper pipe
cutter.

a). it takes a long time for that thickness
b). it bends in the inside of the pipe, making it more difficult to insert
the, er, inserts that need, um, inserting.
