were later independently produced after Phillippe started to sell the imported rods to a New York retailer and then copied by Americans Charles Orvis, Hiram Leonard and Englishman William Hardy in the 1870s and mass production methods made these rods accessible to the public. Horton Manufacturing Company first introduced an all steel rod in 1913. These rods were heavy and flexible and did not satisfy many customers. The next big occurrence in fishing rods was the introduction of the fiberglass rod in the 1940s and was developed by Robert Gayle and a Mr. Mcguire. Boron and Graphite rods came around in the 1960s and 1970s when the United States and United Kingdom invested considerable research into developing the new technologies. Hewitt and Howald were the first to come up with a way to lay the fibers into the shape of a fishing rod by wrapping them around a piece of balsa wood. However, by 1977, boron fibre technology had been muscled out by the cheaper material graphite and was no longer competitive in the market. Rods for travelers were made with nickel-silver metal joints, or ferrules, that could be inserted into one another forming the rod. Some of them were made to be used as a walking cane until needed for sport. Since the 1980s, with the advent of flexible, yet stiff graphite ferrules, travel rod technology has greatly advanced, and multi-piece travel rods that can be transported in a suitcase or backpack constitute a large share of the market. Modern design In theory, an ideal rod should gradually taper from butt to tip, be tight in all its joints (if any), and have a smooth, progressive taper, without 'dead spots'. Modern design and fabrication techniques, along with advanced materials such as graphite, boron, magnesium alloy and fiberglass composites as well as stainless steel (see Emmrod) – have allowed rod makers to tailor both the shape and action of fishing rods for greater casting distance, accuracy, and fish-fighting qualities. Today, fishing rods are identified by their weight (meaning the weight of line or lure required to flex a fully loaded rod) and action (describing the speed with which the rod returns to its neutral position). Generally there are three types of rods used today graphite, fiberglass, and bamboo rods. Bamboo rods are the heaviest of the three, but people still use it for its feel. Fiberglass rods are the heaviest
