I love to cook shrimp. I really don't mind peeling them, but it's the de-veining & butterflying that drives me insane. Repetitive, tedious & downright annoying. Luckily, some clever bugger has invented the Shrimp Butler. This ingenious machine does all the work for you & is reasonable priced at $35.
Although you need to be making shrimp by the bucketload for this thing to be worth the money, I think it's a pretty cool little gadget. They have a demo video on their website, check it out.
