The difference between punching knife and cutting knife techniques in seal cutting (please compare and analyze the aesthetic intention and characteristics with pictures. )

The difference between seal cutting's punching knife and cutting knife techniques. Seal cutting is a traditional art closely combined with calligraphy, which has a history of two or three thousand years. Seal is a practical work of art. The fundamental difference between seal engravers' works and lettering and spreading seals lies in that the former pays attention to chapter and seal method, while the latter mainly relies on description, regardless of chapter and seal method. Seal cutting is a combination of calligraphy and carving art, so the former people called the carving knife an iron pen, and the knife transport method includes two kinds: punching knife and cutting knife. Punching the knife: Push the knife forward with the lines that need to be engraved at the corner of the knife, and press the ring finger against the edge of the stone seal to control the speed of transportation. However, this "punching" is not a matter of punching at once, but a section by section, which can avoid the disadvantage of not being dignified enough, and the punching angle is small, about 3. Cutter: The holding angle of the cutter is straighter than that of the punching cutter, which is about 6. The lines cut by the cutter are short, and the angles fall together, so the long lines are segmented and completed by several repeated actions. Due to the lack of momentum of pure knives, it is generally appropriate to use both punching and punching, relying on the virtual strength of the whole body to transport it between the fingers through the elbow and wrist, rather than relying on the big movements of the hands and hips. Holding a knife, like writing a pen, is generally indefinite. All kinds of knives have advantages and disadvantages. It is nothing more than adapting to the habits of the engraver. Seeing the quality of seal cutting works is not observing the operation performance. However, using a knife-holding method suitable for your own habits can help to engrave a good seal. The editor likes to hold a knife, just like holding a pen. Generally, teenagers are easy to accept. It is fixed by thumb, index finger and middle finger, and the ring finger and little finger are auxiliary to the middle finger, with an angle of about 45. It is received and delivered by the joints of the three fingers, carved from the lower right to the front left, and the direction of knife delivery remains unchanged, which is as easy to launch outward as boxing. After proficiency, you can also change the angle and direction of the blade, and carry the knife to process the details at will. Composition is the art of arranging a word or a group of words on a printing surface, which is complicated and changeable, and it is really the most important link in seal cutting. If one side of the seal has a skilled knife method without a clever composition, there will be no masterpiece. In particular, the creation of complete sets and groups must be changed in all aspects, and it is necessary to show the author's skill in composition. Therefore, when designing Yin Gao, it should be conceived repeatedly. At this point, Wu Changshuo, a master of seal cutting, has a cautious creative attitude which is worth learning. Appropriate forms should be designed according to the specific strokes, strokes, shapes and the relationship between words. Single-knife in the middle of the stroke, mostly used to carve fine Zhu Wen; Double knives cut on both sides of strokes, which are mostly used to engrave coarse white and Zhu Wen. According to the different knife potential, it can be divided into three categories: punching knife, cutting knife and punching combination. According to the different methods of holding knives, the potential of transporting knives and the scars caused by the thickness and dullness of knives, various seal cutting schools have been formed. Although the homework has been handed in, it will be wasted if you don't give it, right? Hahaha.
