A new fundamental delta-wing paper "jet".
Optional dorsal fin makes a Fin Sharky.
It's not for everyone though. It's an "expensive" high-performance plane which is quite difficult to produce.
Learn the design and you will be able to create a successful Sharky on at least some if not most attempts. It's fun and challenging to fold. Amaze your friends and add a new dimension to your paper aviation.
The K-20 dates back over two decades to when I designed it in elementary school. It makes its public debut in 2001 here on PaperAirplanes.net.
The design presented here is the original one. More recently I've been doing some new developments on it and hopefully will have some more about them here before long.
It uses the same basic fold structure to generate the leading rear wing edges as does the K-19. The positions and angles of these folds can be more freely varied in the K-21, so it's good for practice and sometimes if you flub up when making a K-19 you can turn it into a K-21.
