For all we know, the King Taijitu's scales could be thick enough to act as armor, arranged like scalemail.

Blake couldn't cut the giant Nevermore, and it just had feathers. Everything Team RWBY shot at the giant Nevermore didn't work (and yes, some of their shots did actually hit it). The attacks that Ruby, Blake, Ren, and Pyrrha did on the giant Death Stalker didn't work either. Weiss had to flip over the Boarbatusk to kill it because of the bone plate armor on its back and sides.

Some Grimm are just more heavily armored, whether by thick scales, thick feathers, or bone plates.
