Has anyone else experienced this? This pen is wearing out right in my hand. I use it everyday and it gets opened and closed numerous times a day, but it seems to me this kind of wear is going to happen eventually depending on how often it’s used. The area that’s wearing was originally beveled around the edge, but has now worn into a very sharp edge that wears on the side of my thumb. It has also resulted in a ton of aluminum dust in the barrel. I contacted Boker about a possible warranty issue but we’ll see where it goes.
