If you mean his book description, Tonbokiri refers to himself as a creation of the Muramasa school, but he was not made by the founder Muramasa Sengou as pointed out correctly by above anon.

According to this article from Asahi Shinbun, Sano Art Museum where Tonbokiri is currently displayed has the following description for the spear.

佐野美術館によると、蜻蛉切は刀工・村正の弟子、藤原正真（まさざね）の作品と言われている.

Tonbokiri was forged by Fujiwara Masazane who was a disple of the Muramasa school.
