The reason the natives wore their knives around the neck was supposedly to avoid losing it. The reasoning was that you would notice the lack of weight hung off your neck if it wasn't back in it's pouch.

That being said, just because the indians did it DON"T mean there isn't a better way of doing it for yourself.....

They didn't use chainsaws either, but I bet they wouldn't turn one down that was full of gas......
