<p>The invention relates to knife blades and to a method of their production. Knife blades of the type with a hardened surface intended to enhance cutting performance, are known, such as, for example in EP 92908829.2, and EP 93303062.9. Such knife blades display considerably improved cutting characteristics in comparison with conventional blades and the object of the invention is to provide a knife blade exhibiting still further enhanced cutting characteristics. This objective is met by a knife blade comprising a cutting edge formed on a blank, one side of the edge being provided with a coating formed by a particulate material in a matrix, the matrix being softer than the particulate material, and the coating being such that a considerable number of the particulates project from the matrix in the vicinity of the cutting tip of the blade edge, to form the cutting tip.</p> |
