My Father was a B.C. RCMP Officer he always said anything with a Blade longer than 6 inches has to be on your Belt in Plain View and Don't wear a knife in the Bar or the Airport or the Court House. I was warned of the Police Line oh give me your Knife and you can pick it up from the Station and 9 times out of 10 you'll go to get it and it's missing they can't find it. Challenge them say sure I will but you need to sign this paper that your responsible for it when I return to get it which at that point its too much hassle for them to try and trick you out of it. When I was younger My vehicle and my person was searched illegally items were removed so I filed a complaint with the ( Public Complaints Commission ) Against the Officer. The Police will never tell you that a Complaint can be filed. Always Remember Any Knife carried when asked is for utility use. If its being used for Defense make sure its only worth $10 -$30 Dollars because if you have to throw it away I'd rather throw a cheap knife away than a $100-$200 Dollar Knife.
