I've gone up and back down the knife ladder in a somewhat short amount of time (about 2 1/2 years) since I really started collecting. What amazed me at first was of course the utility of a knife, but then there's the blade steel, and engineering involved in creating them.
Our first knives were made of rocks and bone and sharpened by a lucky tap with a harder rock - look what we have available today

We have super steels - carbon, stainless, tool steel, rust proof (H1), etc....and then to add those steel choices to different handle materials, locking mechanisms, sheaths, etc....and it becomes a plethora of knives
I started with a BSA Camilus boy scout deluxe and a SAK classic as early as I can remember. After high school I had my own money and desire to learn about blade steels (which led me here). After learning about blade steels I wanted to learn about all the different locking mechanisms out there, all the handle materials and their advantages/disadvantages. Of course this caused me to slowly go up in price from <$40 up to $500 knives (sebenza, umnumzaan, SMF, SnG). After seeing what was at the top of the ladder I was satisfied and began my descent and found my middle ground as to price vs. function, bang for buck, po-ta-toe po-taa-toe

and that ended up being a 552 Ritter Griptilian for me
The 552 Ritter Grip has amazing S30V, the handle is filling to the palm, is just the right thickness of blade, has enough cutting edge for whatever it is that I will need, has a beautiful stonewash finish (which is my favorite finish), has the 1000 lb axis lock, and if I desire in the future I can get the wilkins grips for it to "customize" the look of it :thumbup:
So, using myself as an example:
1. I collected to learn more about blade steel
2. I collected to learn about handle material
3. I collected to learn about locking mechanisms and their strength/weaknesses
4. I collected to learn about what fits me (hand and pocket)
5. I collected to learn if a more expensive knife really is better
6. I am happy that I did shop around and feel that I found what is a good value to me.
7. I look forward to that new design so I can test it out
