I actually just had to sit down and think about this for a good while.
My first answer was I'm definitely more passionate about knives than I am about the outdoors, hiking, wilderness, etc. I mean, I've been absolutely nuts about knives since I was tiny and I've spent a medium size fortune on them for as long as I can remember. I've always appreciated knives for much more than just their intended uses. I like the shapes, the variety, the artform, everything about them. I love the history that some can carry, the roots that the designs have in history, the feelings that they inspire. I could go on and on forever. I absolutely love my knives and everything about them. I've never spent a fortune on being outside. That was my first series of thoughts.
Then I started to think about how much time I've spent between the two things. I've spent a good deal of my life being, in some way, involved with knives, whether it be from using them, to collecting them, to researching and learning about them. However, I've spent WAAY more time outdoors, camping, hiking, all kinds of stuff. I might not have spent near as much money doing those activities as I have on knives, but that's only because it was always free, for the most part.
After I thought about it some more, I asked myself, "if being in the wilderness/outdoors cost money, would I be willing to sacrifice my love for knives in order to invest in my outdoor activities?" The answer is most certainly yes. I would rather have only a handfull of knives that served their specific purposes and still be able to have all of my outdoors experience and activities. So the conclusion is that I am more passionate about the wilderness/outdoors than I am about knives.
