Reasons why the kola is preferably broken with a knife rather than by
hand?  Many of the answers received   from the questionnaire  indicated that it is due to  health reasons, that is, for hygienically reasons
as the immediate motive. Some people 
say  it is because the   kola is sacred, and as   much should be treated holy  “sanctae sanctae tractate sunt” 
The
popular  reason is that the kola is
broken  with a knife as a mark of  honor to it because it is not    up to the size of a piece of yam which
people bite  and  chew. The remote reason is essentially
religious,  for people  who have 
shed blood develop a “ strong  
hand “  “aka ike”
and may not
break the  sacred kola  for others using the soiled or profaned hand
or   bloody hand. The  sacredness of the oji  stems from the fact that  oji is Izzi symbol of life
