When I was attached to a Motor Lifeboat Station I was told " have a boat knife by monday." Nothing was issued or even suggested. I had a Ontario survival knife from arctic survival school , a stainless steel finnish puukko and a Ulu <img src="images/graemlins/blush.gif" alt="" /> The local State trooper ( with a personal grudge against the coasties) informed me I would be arrested carrying the A/F from the station to the Lifeboat shed.
