Wacky, yes. But ratcheting tools always improve repetitive cranking tasks, so this strikes me as a kick-ass idea. Besides the ratcheting mechanism, this Apri opener also foregoes the whole clamping routine; you just push down on it with your body weight to latch it onto the can.
You can see more detail in the pictures (link below). Slide the lever under the inside edge of the can, then push down on the whole unit and crank away to open. It’s larger than it appears in the photo above — about 5-3/4″ long. And the metal cutting lever is magnetized, making it easier to position.
Now for the bad news: This is another vaporware product, this time from Quirky, a Kickstarter knockoff, which means that to get one you’d have to ante up, wait to see if the “inventor” can make good on the project, then either get one or (hopefully) get your money back.
Of course, you could always just go with Progressive International’s ratcheting can opener [What’s This?], currently available for $14 on Amazon and Prime shippable. That’s $5 less than the “presale” price of the Apri and a hell of a lot less waiting. The Progressive also features a back-and-forth lever motion as opposed to the Apri’s twist action. So the real question is: How important is the lever-less design to you?
