The tsuru (Crane) nib of this Platinum 3776 is nibmeister José Munuera from Niblab's interpretation of the classic Naginata Togi. Starting with a Coarse 3776 nib and through meticulous grinding, it achieves line variation based on the writing angle: fine when writing at a higher angle (more perpendicular to the paper), medium at a normal writing angle, and broad when writing at a lower angle.

The iridium modified by Niblab also incorporates a line variation between horizontal and vertical strokes, allowing for writing with greater nuance.

This model was inspirated in the blue color from Chartre´s cathedral stained glass.
