I bought a Durascoop cat litter scoop about five years ago because the little plastic scoop I'd been using for a couple of years had gotten flimsy from use and would often buckle at the handle.
The Durascoop is made from cast aluminum and will never bend. It easily shaves off hardened clumps of litter from that litter box that would cause a plastic scoop to fold in half. It's actually a beautiful looking tool, too. If Raymond Loewy designed a scoop, it would look like this (except maybe the handle wouldn't be covered with textured plastic).
