Diamond knife

A diamond knife is a very sharp knife in which the edge is made from diamond, invented by Humberto Fernández Morán in 1955. Diamond knives are used for medical and scientific applications where an extremely sharp and long-lasting edge is essential. The knives are very expensive to initially purchase, depending on the quality and size of the knife; in addition the knives must be professionally sharpened as the edge dulls.
