I'll stand by my comment from the first thread about it a couple of years back. No operator on earth is going to use a weapon to tether their lunch to a rock in the surf to keep it safe until dinner time. It just makes no sense. Use your knife as an anchor to secure gear off-shore? Have an empty sheath swinging from your belt while you carry out clandestine or combat operations?
It will sell though. These high-speed, low-drag, bugout packers in Iowa will have one for when the SHTF so they can keep their lunch safe in Lake Placid when the big Gov comes for their guns...
Ditch the grapple to not tempt some hypoglycemic operator from giving up a combat weapon. Make it with a steel that's highly salt resistant and holds an edge that will make it through more than one bad-guy's vest, and use a coating that won't scratch off while opening a pack of cheesy-peanut butter crackers.
All that being said, it does serve the exact same purpose as the original Buckmaster. If it had a compass, I'd be a buyer...
