The Wall St. II (Woodcraft) and Sierra (Rockler and others) pen styles offer a "satin" finish option which is located on a large area of the nib. I am wondering if anyone has any information about how durable (or not) this finish is. This plating is located in the area where the user would be gripping the pen, so I wonder if wear is an issue over time due to friction with the user's fingers. Any feedback about this would be greatly appreciated, I'm new to pen-making and don't know if this is a commonly-known issue or not. From what I understand so far, a satin plating is far from the most-durable plating available. Should selling pens with this finish be avoided?
