division-based last mechanism where the last is sawed into two parts, the top of the cone and the rest of the last, which are screwed together through a hole in the top accessible above the topline or within the shaft of the upper when lasted. The last is removed in pieces by first unscrewing and removing the cone block, then removing the rest of the last.
Wooden scoop-block lasts are popular among bespoke shoe makers.
Spenlé calls this style as “2-part dividing”. Spring Line calls it “scoop block”.
