    Abstract: A hair braiding tool for fusing the end of a braid of synthetic fibers includes a first elongated member having at least one substantially semi-cylindrical transverse groove formed in a surface thereof with the groove having an open end and a closed end and a second elongated member pivotally connected to the first elongated member and having at least one substantially semi-cylindrical transverse groove formed in a surface thereof with the groove having an open end and a closed end. Upon bringing the first and second members into engagement with each other, the semi-cylindrical grooves therein mate with each other to define a cylindrical passage having an open end and a closed end for receiving a braid end therein. An electrical heating element is disposed in contact with the closed end of the cylindrical passage for trimming and fusing the braid end.
