Japanese: 縄師
Nawa (縄): Rope
Shi (師): Roughly translates the “teacher”

One doesn’t boast about being a ‘shi’. One gets labeled a ‘shi’ because they’ve overcome huge barriers with their own hard work.
Mai Randa

A term meaning “teacher of rope”, the one who ties.

A person that has reached a certain degree of proficiency in handling nawa.
This is considered a grand title for all but the most accomplished rope artist.

Expectations/standards for that in Japan are quite high not just “play” rope.

RopeMarks (Bob Roos) is (proudly) recognized as a nawashi.
