Carbon fibre bottle opener

I found this kickstarter project, showed it to my college and bragged about being able to produce something like this for quarter the price.
He didn't believe me. I went to eBay to get some material.

Three days later I opened his beer with this. Handmade out of 1,5mm carbon fibre.
The plate I got was big enough to produce two more, I ended with around 4€ per piece.

Opening bottles with it feels strange, but works fine. The material is so strong I can't break it with my hands.
