Aichmomancy (from Greek aikhmē, spearhead and manteia, prophecy) is a form of divination somewhat similar to Acultomancy in that it uses sharp pointed objects to show patterns to read.
Aichmomancy readers use pins, knives, forks, nails, and handmade pieces of wood sharpened to a point. Readers drop sharp pointed objects onto a flat surface, find patterns and interpret them.
In the most ancient form of this divination a spearhead was spun in the sand. Several centuries later, during the Early Middle Ages, divinations with pins became popular in Europe. Readers used seven pins and a table covered with cloth. Pins were thrown over the table, and the patterns were read and interpreted.
