This is one of my initial prototype nibs.
previously, i tried with Titanium, stainless steel materials.
The silver nib offers a bit of softness.
the point of this nib is tungsten carbide.
it will probably last 5~10x more than iridium points.
however, it does tarnish a bit to black color.
also, the writing feel may be inferior to iridium points.
it is extremely hard material.
