In a sanding block having two expansive sides and two adjacent sides, each adjacent side adjoins each expansive side at a given one of two opposite edges of that expansive side. The expansive and adjacent sides are abrasive. When viewed macroscopically before the sanding block becomes worn, the expansive sides between their opposite edges are planar and are parallel, a given one of the opposite edges of each expansive side is a curved edge, which defines a radius not less than about ⅛ inch at any location on the curved edge, and the other one of the opposite edges of each expansive side is a sharp edge, which defines an acute angle in a range from about 55° to about 70°.
