The craft of making harpoons in Hongze Lake is a traditional craft item in the second batch of representative items of municipal intangible cultural heritage in Huai'an. Historical evolution According to archaeological excavations, there is a bone tool called "fish dart" in the Hongze Lake area. Experts have identified it as a fishing and hunting tool in primitive society, and it can also be regarded as the predecessor of the harpoon. It seems that thousands of years ago, the ancestors in the Hongze Lake area were engaged in fishing activities. In the album of traditional Chinese paintings from the Qing Dynasty collected by the Hongze Lake Museum, there are scenes showing fishermen forking fish. Since humans entered the Iron Age, with the increasing prosperity and increase of the production of iron products, iron tools have become an indispensable production tool in people's daily life. The invention and use of the harpoon is the crystallization of the wisdom of the fishermen in the Hongze Lake area in production practice. It is small, flexible and practical. It can be used in groups or by one person. It is an irreplaceable fishing and hunting tool. Main content The production of harpoons in the Hongze Lake area is made through chiseling, grinding, bending, hooping and other processes. The iron plate or iron bar is forged into fork teeth and finally installed. Chisel: Select an iron plate suitable for the length of the fork teeth, clamp it with pliers, put it into the furnace for calcination, take it out in time after it turns red, put it on the anvil, and chisel it into 6 iron bars about one centimeter wide (generally, lantern forks have 13 teeth). Now, finished iron bars are mostly used. Roll: Put both ends of the iron bar into the furnace with fire, roll them into thin tips, curl them into whiskers, and then roll them into fork tips, with the tip about five centimeters long. Bend: At this time, bend each bend into a "U" shape, with the mouth slightly open outward, and the spacing is not waiting. Make another flat fork bar about fifty centimeters long, fold it in half first to make a fork clamp, and roll one end with fire into a barbed tip to make the center tooth. Then, clamp the "U"-shaped racks in the center teeth, with a spacing of about one centimeter, and put them into the furnace with fire to connect. Then rotate the "U"-shaped teeth from top to bottom in the same direction, one by one, at a certain angle, so that the upper and lower ends are at right angles (looks like a lantern). Finally, grind the lower end of the fork clamp into a square pointed fork handle, which is generally equidistant from the lantern fork teeth. Hoop: embed the finished fork body into the root end of a green bamboo of appropriate thickness, plug it with a wooden plug, and then tighten the joint with wire. The tools for making harpoons include bellows, anvils, sledgehammers, hammers, pick hammers, pliers, chisels, etc. The products include flat forks, clam forks, lantern forks, etc. The Hongze Lake harpoon making technique is the crystallization of the wisdom of Hongze Lake fishermen. It has certain historical and cultural value. It not only enriches the types of fishing and hunting tools, but also enriches the traditional manufacturing process, and has certain research value.
