I write some reviews, but it is true that this product met all the conditions here for me to take the time to go over my nerves. As one of the latest reviews, the quality here is not by appointment, too coarse fibers, nonexistent finishes. So after a time expensive knives have trouble inserting it. Finally the fibers cling to the knife and bend, break and end up making unusable the knife block. This also put pressure on the thread of the knife that eventually wear out before. I can assure you that I am a very sensitive, especially with my expensive knives!
