Don't know about the one you have a link too,
but this is what I use:
VINTAGE AMERICAN CORN CUTTER Design 185,140 - (item 260148009423 end time Aug-14-07 16:15:29 PDT)
I was a bit disconcerted to see it listed as "vintage". I bought mine new, a "few" years ago
. I used a tip I saw recently on another corn thread here, and soaked my blanched corn in a sink full of ice water, before cutting the kernels off the cob. It really did cut down on the splattering. i bought a 22 pound bag of ice and used every cube.
I have always blanched the corn cobs before removing the kernels, so I have no experience with cutting the kernels off raw.
