The Tachikawa T-600 is similar to the Tachikawa G, but is much stiffer and can handle more pressure. This spoon-shaped nib is also similar in appearance to the Hunt 513EF Nib. Smooth and capable of holding a lot of ink. Extra-fine point creates delicate hairlines, and a lot of pressure is needed to create thick swells, making this nib great for heavy-handed calligraphers. Suitable for monoline lettering, modern calligraphy styles, and Copperplate. Calligraphers of all skill levels will enjoy this nib.
