Claim:
1. A diamond tool comprising: a body with a thickness of 1 mm to 2 mm; a tip portion formed along an edge of the body, the tip portion being thinner than the body; and a brazing bond layer having a brazing bond and diamond particles having a particle size of 25 to 50 meshes, wherein the brazing bond is formed on the tip portion to secure the diamond particles with the brazing bond, wherein the brazing bond layer has a greater thickness than a difference between half the thickness of the body and half the thickness of the tip portion, such that some parts of the body can penetrate into a surface of an object to be cut, wherein the tip portion has a plane section with a uniform thickness, wherein an outermost surface of the tip portion is convexly curved in a plane perpendicular to the plane section, wherein a value obtained by subtracting a difference between half the thickness of the body and half the thickness of the tip portion from the thickness of the brazing bond layer ranges from 10% to 70% the particle size of the diamond particles, and wherein the tip portion has a thickness ranging from 50% to 80% the thickness of the body.
