It's still an impractical knife (the question in the OP) regardless of whether the handle is hollow or not. That, and their expense, is why so few are actually used in the bush. Even the fictional character, John Rambo, had a like new custom knife --- one of the believable aspects (excepting a drifter having a custom knife) of the film.
When I need a large knife I just stuffed Glock Field knife (hollow handle but for different a reason) and/or a Lao machete in my ruck. At $25 for one and $1 and a pack of cigs for the other, I was never in want of any other large knife. They were actually used hard without even a second thought. Note the Glock sheath is in excellent condition. It rode in a ruck when it rode.
