Comment 2 for bug 170132

I used to use the razor tool using sign software when
working at a sign graphics company a few years ago proofing
vector artwork for large format billboards and signs. The
tool equivalent to what this user describes as razor was one
of my bread and butter tools. As buliabyak mentioned you can
do cut path and divide, but these both take many more steps
than a razor tool. It is important that this tool should act
on all objects beneath it at once, no matter which ones are
selected, and it should be able to snap to guides. This is a
very powerful tool because of its speed, one I couldn't have
done without when doing professional sign proofing.
