A cutting tool, preferably in the form of a cutting insert of hard material, having a narrow land area or ledge along the cutting edge, forming a shallow recessed groove promoting the formation of a false cutting tip build-up during use of the cutting tool, the cutting tip build-up resulting from the transfer of material from the chip to the ledge surface. The invention further contemplates favoring the formation of cutting tip build-up by providing a plurality of diamond particles embedded in the ledge surface at least at the cutting tip of the tool.
