Engineering:Macharomancy

Macharomancy (Greek makhaira, a short sword or a dagger, and manteia, prophecy; alternative spellings are machæromancy, machairomancy) is a form of divination by interpreting knives, daggers or swords, one of many methods of divination based on the use of weapons (cf belomancy – by arrows, axinomancy – by axes, and other).
