You're post just made me think of something...one of the places people mention using a knife lanyard is on a boat, so it doesn't go over board and sink out of reach. But for a lighter knife, a floating key chain might be a better tool. The knife can still fall free from your body, but if it lands in the water it will float safely on top. Not for fast moving boats or inclement water, but what do people think?
