A cutting edge which has improved resistance to scratching wear, such resistance being required for cutting edges for snow removal, which has good performance to increase e.g., compressed snow rate, and which can be manufactured at comparatively low cost. The cutting edge comprises a hard member provided at the leading edge of an edge body, the hard member comprising (i) a hard material containing hard grains which are dispersed with high filling density and integrally combined by a metal having a lower melting point than the hard grains and (ii) a protective member which covers at least the front face of the hard material as viewed in the travel direction of the blade and which has impact resistance.
