Our fins are made from start to finish in our workshop - nothing is outsourced.  We're a family outfit, and as such, our workshop is based in the basement of our parents' house.  In actual fact, we built the workshop too, floors, walls - the lot, converting the garage into a functional work space.  Pretty much every bit of furniture has also been built by us, and many of our tools we have developed, adapted and modified to our needs - our engineering backgrounds have come in useful at every stage!
