Matsunaga, which produces the brands KING and SUN TIGER is perhaps the best-known manufacturer in Europe. Its strong point is producing very traditional soft stones that abrade quickly to reveal new sharp cutting particles. These kinds of stones must be dressed very often to keep them flat and effective. Stones are relatively soft and have a comfortable feel in use, because one can see and feel the stone cutting the surface. These types of soft stones must be resurfaced relatively often however, as a hollow quickly develops in use.
