I keep it sheathed in my daypack along with my other game processing gear. It's harder to lose a daypack.......

.
It also helps to protect the knife/sheath more when you take a spill, which while hunting, isn't unheard of. And IMHO......keeping it in a daypack or another type of pack might also offer a bit more self protection from being impaled during a fall, especially when your knife isn't sheathed in either a very secure sheath or a rather cheaply made/thinner/less 'bulletproof' made sheath.
Some might hate to have their trusty knife less available to them as when in a daypack of some sort, but in reality, it should take only seconds to secure if necessary. If seconds might seem too long for your needs, such as in an instance of a 2 or 4-legged attack, the firearm you're hunting deer with will likely suffice much more effectively than a knife.
When preseason scouting or when out hiking, I always carry a sidearm and a woods knife is always with me, as well. But, as above, the knife is secured in my daypack. If either my hunting rifle or handgun were to be damaged enough in a fall to render either useless, I would then wear my knife on my belt where it would then become my primary source of protection.
Knives are so very useful in so many ways and seem to be a great source of 'comfort' for many, as well, but IMHO, unless in the hands of a well trained person, they can unsafely boost one's level of confidence.
Good luck this season and I hope you get to use that knife, no matter where or how you choose to carry it.......
