Sure, if you wear it on a belt for a hiking trip or similar light duty, just use some paracord to provide a leg loop with a looser constriction tension to it. Just enough to prevent any serious flooping around. More serious ops may dictate a tighter hold.
I've also seen these types of sheaths attatched to daypacks, harnesses, suspenders and such, and the eyelets would also be useful then too.
In a pinch, long shoelaces can be used in place of paracord. In fact, recent surplus offerings of the official USAF pilot's knife of days past come supplied with just such laces.
Good choice on the Becker!
