Not only suitable for soft wood. If you grind something else, they won't give a permanent pattern. Especially at the fiber end, the grain resists sanding, while softer woods sand easily, resulting in a "hills and valleys" texture. I found this disappointing as wood is one of the advertised uses for this product. It's a bit misleading in my opinion. It's probably great for other materials, but not wood.
