The Kuhn Rikon Auto Safety LidLifter's single-handle design and top-mounted knob draw mostly positive reviews; although, the lack of a scissors-style grip means you cannot vary pressure on the can. Push-button pincers help you lift the lid off once you're done, and the side-cut design leaves smooth edges on both can and lid. We found some durability complaints but nothing out of the ordinary for a smooth-edge can opener.
No more squeezing handles together. The Kuhn Rikon Auto Safety LidLifter opens cans along the side, leaving a smooth edge on both lid and can. The single-handle design means you don't have to squeeze to make it work, but the trade-off is you cannot adjust the amount of pressure applied to the can. This can opener earns a nod from Carol Eustice, About.com's expert on arthritis, for being arthritis-friendly. However, a few users contend the way the knob is positioned (your hand must be palm-down as you twist it) feels awkward and hard on the wrist. Metal pincers help lift the cut lid off the can.
Decent to good durability. Most reviewers say the Kuhn Rikon Auto Safety LidLifter's stainless-steel cutting mechanism is relatively durable, but it's not perfect. Some users claim the Auto Safety LidLifter stops cutting all the way through the can on the first pass after just a few months. This is a common issue for smooth-edge can openers. The Deluxe version of the LidLifter contains more metal parts, but still produces only mediocre durability. Some users also see the plastic button that activates the lid-lifting pincers as a potential weak point, although it holds up at least as well as the cutting mechanism. The Kuhn Rikon Auto Safety LidLifter (as well as the Deluxe version) comes with a two-year warranty.

The author and some unidentified helpers evaluate six manual can openers for criteria like grip comfort and ease of puncture. The test included the Kuhn Rikon Auto Safety Deluxe LidLifter, which they find easy on the hands because you don't have to grip the handles.
