I'm a bit of a knife nut I guess, so rather than buy a cheaper knife expecting to LOSE it, I buy slightly pricier knives expecting to KEEP them!
Having said that, I really like marlinspike ropework and fancy knots, but am still learning the basics. In the meantime, I found a very PRACTICAL simple lanyard set-up as posted in the following video.
I plan to use this set-up during an upcoming canoe trip. Take Care!
