The word "zipper" isn't usually in such close proximity to "corn" (or any other vegetable). The Kuhn Rikon Corn Zipper, with the corn-on-the-cob design on the handle, is such a great kitchen utensil, we don't care what it's called.
The Swiss-designed Zipper, made of stainless steel and a durable plastic handle, cleanly and quickly strips cooked kernels from the cob. It sells for about $12 at multiple retailers; but the best deal, $22, includes the zipper and an accompanying pack of 18 heat-resistant corn holders that can be screwed into ears of corn even before putting them in boiling water. The Zipper and holders are all dishwasher safe.
A rose by any other name is still a rose. The Kuhn Rikon Corn Zipper by any other name is still one of the coolest new gadgets around.
