I don't know if this is originally Danish in design, but Denmark's the first place I've seen one, so for now at least I'll give them credit for it. Made by Danish stainless steel manufacturer Raadvad (although we've got a Swedish one in the kitchen drawer too) this is the most simple and sleek looking can opener I've ever seen. A little more laborious than the ones I'm used to, perhaps, you use the protruding blade to cut you're can open while the little ridge beneath hooks under the outer rim to give you the torque you need to get the job done. Fantastisk.
