Tenkara rods Tenkara rods are a type of fly rod used for tenkara fishing in Japan. A mixture of the rods in the other categories, they are carbon rods, fly rods and telescopic rods all in one. These are ultra-light and very portable telescopic rods (read more about telescopic below). Their extended length normally ranges from , and they have a very soft action. The action of tenkara rods has been standardized as a ratio of "how many parts are stiffer : how many tip parts bend more easily". The standard actions are 5:5, 6:4, 7:3, and 8:2, with 5:5 being a softer/slower rod, and 8:2 being a stiffer rod. Similar to western fly-rods tenkara rods also have cork, and sometimes even wooden handles, with wooden handles (such as red-pine, and phoenix-tree wood) being the more prized rods due to their increased sensitivity to fish bites and the heavier feel that helps balance the rods. Tenkara rods have no guides. Tenkara is a fixed-line fishing method, where no reel is used, but rather the line is tied directly to the tip of the rod. Like the carbon rods mentioned above this allows for "very precise positioning of the fly which in turn enables huge catches of fish with accurate feeding". One of the most common flies used in tenkara fishing is the Sakasa Kebari. Tenkara fishing is very popular in Japan, where these rods can be found in every major tackle shop. In the US, tenkara is beginning to grow in popularity. Spin casting rods Spin casting rods are rods designed to hold a spin casting reel, which are normally mounted above the handle. Spin casting rods also have small eyes and, frequently, a forefinger grip trigger. They are very similar to bait casting rods, to the point where either type of reel may be used on a particular rod. While rods were at one time offered as specific "spin casting" or "bait casting" rods, this has become uncommon, as the rod design is suited to either fishing style, and today they are generally called simply "casting rods", and are usually offered with no distinction as to which style they are best suited for in use. Baitcasting rods While the easy to
