As in other countries, Germans don't celebrate Halloween per se. On Nov. 1, Germans who are Catholic celebrate All Saints' Day. Taking it a step further, in southern Germany, residents celebrate Oct. 30 to Nov. 8 as All Souls' Week, and remember their beloved dead by visiting gravesites and perhaps attending Mass in their honor.
But the more unusual custom is the knife-hiding. On either Oct. 31, Nov. 1 or throughout the entire All Souls' Week (Oct. 30 to Nov. 8) — depending on the German region — people also stash away their knives in safe places. This tradition stems from an old belief that spirits come home to visit at this time. And no one wants to inadvertently slice or dice a ghost while chopping veggies or slicing bread. So Germans felt it was best to hide all of the household knives [source: Sawyer]. Now the practice is merely a fun tradition.
