How to make a knife?

First, the woodcut knife. It is made of solid steel bars, with sharp angles of various shapes at the cut of the cutter head as the cutting edge, and a round wooden handle at the end of the cutter. Hold the whole knife in the palm of your hand, expose the cutting edge with your thumb, and push the handle horizontally with your wrist to carve lines, which is suitable for carving fine products. Second, the woodcarving knife. Triangular, round and square groove blades are the main ones, supplemented by flat blades and bevels. Holding a knife to draw a line is roughly like holding a pencil. When the big round knife cuts thick lines, put the top of the handle in the palm of your hand and push it hard to carve. Inclined knives and flat knives can also meet the needs of carving, but the way of holding knives needs to be changed.

Second, to make a big round knife, you can first insert the nib into the pen holder and fix it, then polish and file the tail of the nib into an arc, and then sharpen it.

Third, make a medium-sized round knife. First, use pliers to clamp the two sides of the nib into a proper arc, then smooth and file off the redundant parts on both sides, and then sharpen the blade.

Fourth, a small round knife. It can be made of medical No.9 injection needle or veterinary injection needle, or made of steel bone of old umbrella.

File the steel needle half or one third first, because the needle body is too long to be forced. The manufacturing method is to smooth the knife edge first, and then use a file or a grindstone to grind the knife edge into a gap about 2 mm long. The cross section of the notch must be less than a semicircle, otherwise the sawdust cannot be automatically picked out and the blade is blocked. The grinding method of small round knife is the same as that of large round knife. The left hand refers to the blade, and the right hand holds the handle and grinds it to a sharp point. Finally, in order to protect the blade from being broken, you don't have to use a stone mill, you can use charcoal instead, or you can rub a little toothpaste or copper oil on the leather for internal and external friction. The meat cleaver that has been used for a long time at ordinary times can also be wiped in this way, so it is not necessary to grind it again.

Five, small square knife. The smallest square knife cuts lines between the circular knife and the triangular knife. The edge of the knife falls off slightly, which is the line of triangular knife, but it has a round taste, and the front is carved, and the line of fan-shaped round knife has a square taste.
