This is an Live Oak Father Sing twist pen and mechanical pencil set. Designed by author and professional woodturner Dick "Father" Sing, this pen is Dick's favorite style pen. The narrow, larger diameter center band gives the finished pen a double-taper look reminiscent of traditional "click" style ball point pens. The pen and pencil is made with durable 10k gold plated accents. The pen uses a Cross® style refill that features a premium Swiss-made carbide writing tip for smooth consistent writing. To replace the refill, pull off top of pen above the center band and twist out the refill. The pencil is specially designed to feed the correct amount of 5mm lead with each click of the plunger top. The eraser is under the plunger cap and the eraser is pulled out to refill the pencil with 5mm leads. A highly polished lacquer finish was used to protect the wood. These hand made pens and pencils make wonderful gifts and are absolute treasures to own!
