I have a havalon with two blades, a saw blade and a normal blade. I also have an outdoor edge folding knife. Ive been reaching for the outdoor edge more often lately for cleaning game. I prefer the way their blade replacement mechanism works more than the havalon.
Years ago all I carried was a Buck 110, the went to a Kershaw folding. As I have moved further in this journey, I like a small knife. I do have an Outdoor Edge replaceable blade folder I carry now along with a good fixed blade. They each have their use.
I have. Folders are a pain to clean and I will take a few extra ounces to have both a folder and a fixed blade.
Not a fan of fixed blades that are either large or heavy though. I would probably just use a folder if the only fixed blade option was a BK-16 for example.
