I'd agree with the recommendations for laminate trimmer, router, or dremel for the cleanest edge.
one more trick with laminate -- after contact cementing in place, you want to weight it down all over while the cement thoroughly dries, like overnight. If you're glueing it together before installation, this should be fairly straightforward, using stacks of books or cans. If the piece is in place, you may need to get more creative with clamps, rods, etc.
(We had a kitchen design/remodel business which we sold for the $$ for our cruising kitty. And the carpentry skills are still pretty good for barter, now...)
