This gets asked a lot, and it's an interesting study in where a person's mind goes.
Do you gravitate toward a Dooms Day scenario where every function that a knife can perform will be pressed into service? Do you see yourself as an outdoorsman needing a blade that can tackle the wilds and build a shelter? Do you just see yourself as you are and ask, "What do I NEED?"
All three of those would garner different answers from me.
I would say that if I needed a knife that could do most everything I need of a knife that would not only be practical but tough and with a good track record... CRK large Inkosi.
I could do my job for the next 25 years with nothing more. I could survive a short stint in the wilds with it if it were all I had. It will hold up to decades of hard use and stay tight and in tolerance.
But I'm glad 8 don't have to choose just one....or 10.
