Blue Oar is a technique that uses a circular disk of Shinsoo to move rapidly in a certain direction.
Shinsoo is used to form a blue disc, which allows the rider to move at a very great speed. The main usage is for single transportation; the user moves quickly from point A to point B, generally in a straight path. However the technique has been seen to be able to turn on sharp corners. Also, due to the great speed and momentum the technique produces, it can sometimes cause destruction along its pathway and can also be used to break through barriers.
