I actually own one of these, so I am going to abstain from this one. b_leblanc, I am pretty sure I did a corn shucker (different model, but similar) many pages ago!
I have one of those and it doesn't look like that so I didnt say anything but with my luck I'd be wrong.
Yea, the key end is usually not rounded. Looks like you can use that tool for cooking hot dogs in a campfire instead of one of those big forks. Maybe it's something used in boiling crawfish or making outdoor jambalaya. I don't know.
