1. A method for producing a cutting tool comprising the steps of:
coating a portion of a tooth tip of a tooth with cutting particles to form a plurality of geometrically undefined cutting edges;
coating a portion of the tooth tip of the tooth with buffer particles having a circular cross-sectional shape and being made of a different material than the cutting particles in such a way that the buffer particles are located between cutting particles; and
removing the buffer particles so that free spaces are defined between the cutting particles.
