We finally broke down and bought a new can opener while we were at the Weg today. We bought the recommended OXO Good Grips Smooth Edge Can Opener, which looks disturbingly gynecological in this picture, but seems just fine in real life. The only real drawback was that it cost $20. They had the (also recommended) kind that didn't leave the smooth edge, but they were only $6 or so cheaper and I have a tendency to slice my fingers open, so I thought, why not splurge.
We also bought this pink ice cream scoop from Zyliss. Also sort of overpriced at $10, but hopefully it will do a better job than our current scooper.
