A grinding apparatus includes at least two oppositely arranged series of surfaces in slanting relative orientation and alternately overlapping each other, forming this way a groove into which an edge or cutting edge is insertable for polishing by the surfaces. The surfaces of each series of surfaces are arranged in a common plane forming a side in a respective block, the blocks arranged in a holder by which each block is spring biased towards the opposite block, the blocks operated in reciprocating movement transversely to the longitudinal direction of the edge/cutting edge while the surfaces contact opposite sides of the edge/cutting edge under spring action. A grinding block utilized in the grinding apparatus includes a series of individual surfaces arranged in a common plane forming one side of a block divided into sections, which are separated through intermediate recesses into which corresponding sections of an oppositely positioned block intermesh in a toothed engagement while forming a groove between the surfaces.
