The present invention relates to a pneumatic tire formed with a kerf, and a kerf blade for forming a kerf therefor, and more specifically, to a pneumatic tire formed with a kerf that increases a binding force between blocks, and a kerf blade for forming a kerf therefor. Therefore, one embodiment of the present invention provides the pneumatic tire formed with the kerf, including a tread portion (100), a side wall portion (200), and a bead portion, having a block (300) and a groove (400) formed on the tread portion (100), and having the kerf formed on the block (300). A kerf (500) includes inverted triangular protrusions (511) having the base formed at an upper side to be arranged in a line on one side surface (510) of the kerf (500), and triangular protrusions (521) arranged in a row on the other side surface (520) of the kerf (500). The inverted triangular protrusions (511) and the triangular protrusions (521) are located to engage with each other. According to the present invention, since the 3D kerf structure firmly maintains the blocks inside the pattern, it is possible to expect the effects of increasing the traction and improving traveling performance on the wet road surface without canceling handling and wear.
