Aichmophobia (pronounced [ik-mo-fo'be-a]) is a kind of specific phobia, the morbid fear of sharp things, such as pencils, needles, knives, a pointing finger, or even the sharp end of an umbrella and different sorts of protruding corners or sharp edges in furnitures and building constructions/materials. It is derived from the Greek aichme (point) and phobos (fear). This fear may also be referred to as belonephobia or enetophobia.
