The fishing rod is divided into two kinds: hand rod and sea rod. The length of the hand rod, usually between 3.6 and 7.2, and the short rod of 2.5 meters, often used for fishing or fishing in the tent. Made of bamboo pole, river Reed, fiberglass, carbon steel and other materials. For the convenience of carrying and storage, people have long known how to make fishing rods into multiple knots, from the tip to the next section thicker and thicker to each other. The number of sections varies according to the length and material selection, some 80 / 110 cm per section, a total of 4 / 5 sections. Some are only 60 centimeters long and 80 centimeters long. When you don't have to go through the details, it ends up in two knots. Before the 1950 s, the best was a Japanese double fishing rod made of river reeds. Later, fiberglass was invented, and then carbon steel was invented, which was light and durable, and each section was intertwined with each other according to its thickness. It was very convenient to extract it from inside to outside when it was used. It is also made of aluminum and is lighter in weight.
Carbon steel, by contrast, is lighter than fiberglass. Better toughness, for the current most advanced material. However, it must be noted that it can not be used under high voltage wires or thunderstorm weather because of its strong electrical conductivity.
