Chain-holder blade including a shaped body (10) exhibiting a peripheral profile (12, 14) provided with a groove for housing and guiding the diamond-encrusted chain, characterised in that the peripheral profile is formed by several attached elements (26) made of an abrasion-resistant material, along the profile of which the diamond-encrusted chain passes, and in that the profiled body (10) exhibits, at least in the part corresponding to the return travel or non-operative travel of the diamond-encrusted chain, an essentially straight pathway. <IMAGE>
