The gear shift pen has a bolt action on the side with a 5 speed handle. You need to "shift' through the gears to extend the tip. A crow bar makes the clip with tire tread around the cap and the tip. On the top of the cap is a hubcap. This pen has a silver finish and is made of padauk, a beautiful exotic wood. It uses a Parker refill. This pen makes a wonderful gift for your favorite car fan.
