A scraper blade for a conveyor comprising: a blade body having first and second opposing ends and having a forward side and a rearward side between the first and second ends, wherein the second end of said blade body provides a scraping edge and wherein the first end of said blade body provides a base for mounting the scraper blade on a blade mount of a conveyor, and said blade body having a plurality of elongated recessed features extending across the rearward side thereof, wherein the elongated recessed features are spaced apart and are generally parallel to the scraping edge of the first end of the scraper blade, at least one raised feature extending across the rearward side of said blade body, wherein the at least one raised feature is generally parallel to the scraping edge of the first end of the scraper blade and is further from the second end than are the elongated recessed features, whereby a feathered edge produced by wear at the scraping edge tends to separate from the blade body when the scraper blade wears to one of the recessed features, thereby to leave a renewed scraping edge on the scraper blade, and whereby the at least one raised feature provides an indication of wear of the scraper blade.
