For years and years my hunting group has used only replaceable blade knives. But in recent years we have moved back towards using a real knife. My brother uses a Goat knife, which he has used on several bears, mule deer, whitetails, and elk, and my dad uses a buck 110, and a bench made bugout. I have been using a Chris Reeves Iyoni recently, that I won in an Exo Mtn gear giveaway. I really really like it. It’s American made, sturdy blade that sharpens easy, and holds an edge through cutting up a whole mule deer.
In my opinion, the best knife is one that you like, (wether that be because of nostalgia, style, or how it feels in hand), a knife that keeps its edge, and a sturdy knife that you can rely on, and know it’s not going to break on you.
I just carry my one fixed blade other than my leathermen. I like to carry a small sharpener so I can tune up my blade if necessary.
