Microcarvings pay special attention to the selection of materials. The stone material should be absolutely pure, and there should be no sand grid or half silk cracks, because half a sand dot may damage a fine picture or more than 10 Chinese characters. Secondly, the micro carving knife is also a special thin knife, which should be sharp and sharp. It is necessary to have a particularly proficient knowledge of calligraphy and traditional Chinese painting. When carving, "meaning carving" and "meaning carving" can be carried out. Hold your breath and concentrate on your thoughts on the spot. The knife should be stable, accurate and ruthless. The micro carved knife is just a pen. The skill is not enough. Because the knife is slightly out of control, it doesn't reach its purpose. The calligraphy effect must be paid attention to when matching the micro engraving inscriptions on the micro sculpture works. The creators should avoid the ugly appearance, the skew of characters, the uneven lines, the inaccuracy of paintings, and the imbalance of matching. We should grasp the artistic effect of the line changes produced by cutting tools and customized stones. Only in this way can calligraphy and knife techniques and strokes be perfectly unified.
