I cut it with a knife.Which is the proper rewrite?
a) I
used a knife to cut it.b)
I used a knife to cut it with.Should
with be attached to the end of the sentence?
I vote for (a), but another person votes for (b). I don't think I'm wrong, but I'm not a native speaker of English, so I need a native speaker or two to comment on this. Thank you.
