Title: Doesn't work well
Review: This is the second one I've had. The previous one worked great. The metal serated edge was staked on with plastic, and upon opening a small jar, it torqued it out. So, I bought another, and was glad to see they used metal rivets this time. However, they changed the serated edge, and now all it does is saw through the tops. I hope they redesign it again.
