To provide a precise cutting tool which includes abrasive material particles having less variation in the particle diameter than conventional materials, even in a relatively large particle diameter.

A plate sieve having polygonal holes in a plate is used to select a particle size to provide abrasive material particles. A precise cutting tool includes a blade with the abrasive material particles having a particle diameter slightly larger than the thickness of the blade and extremely less variation in the particle diameter, embedded in the blade.
