Although I have turned many pens, I turned a body for, and assembled a Dayacom Sierra pen for my own use. I am impressed with the smooth action of the transmission. It flatters my workmanship with a pen that feels as good as it looks. I am sure it will last me a long time. Although not as popular amoungst pen turners as the streamline, I encourage more turners to make this pen as it is a thicker, heavier pen. An excellent gentleman's pen, and you only have to make one piece, not two! An other bonus is being able to create a Parker style writing experience, whether for yourself or to sell on.
