Colorado Boomerangs has been hand crafting real aerodynamic boomerangs since 1987. The weight and durability of the wood is important and you need real airfoils for each wing. Colorado Boomerangs are light enough to be able to generate a lot of spin with the throw and they are also durable to withstand hard landings. They are made from 10 ply airplane grade plywood imported from Finland. Remember, boomerangs are like little airplane wings. They need to "fly" and being both light and strong are important criteria.
