The cutting edge is arc-shaped, which is mostly used for round and round dents. It is also very useful in carving traditional flowers. For example, the round surfaces of flower leaves, petals and flower branches need to be conformed with a round knife. The horizontal movement of the circular knife is relatively labor-saving, and it can adapt to large fluctuations and small changes.
There are also positive and negative round knives. The oblique surface is in the groove and the back of the knife is straight. It is a positive round knife. It eats wood deeper and is most suitable for round carving, especially in the blanking and digging stages. The bevel is on the back of the knife, and the straight in the groove is a round knife with a reverse mouth. The shape of the round knife can also be made into a curved shape of an iron rod according to the needs, so as to extend into a deeper part and dig a hole.
