So, my fellow knife knuts, I am quite certain that this topic has been discussed a zillion times over the years. I would like to throw my hat in the ring and try to explain how I, personally, contrast the differences between being a collection worthy piece, or a user. I currently own a multitude of folders and fixies of all calibers from Kershaw's to customs, and I love all of them, but that doesn't mean that I will use all of them. I have heard knife makers say that their knives are meant to be used and will serve for a lifetime, but then they put a mirror polished blade inside of scales made from meteorites. So I have made up my mind that if a knife is rare (maybe 10 or less) and made of materials that can easily tarnish or damage, it's probably not going to see use. I am not wealthy by any means (check to check) so when I am blessed enough to acquire a piece of said magnitude, I determine that before I pull the trigger, where it fits in my life. I am always looking at knives that could serve me in my daily life and in an emergency situation. Some would say that one knife should be enough to serve you for life if you take care of it, but where's the excitement in that? Then a knife pops up that I fall in love with that I know that I will never use. It will sit in my case and just look pretty. But that is why I bought it. I know the purists are ready to pounce, but rest assured that when I buy a knife, I buy a knife for a purpose. Whether it is to serve as an edc beater tool, or a piece to look at, play with, and bring me personal satisfaction. So how do you knuts determine what is collection worthy and what is user worthy?
