This has been a long time coming? As I sit here looking at my collection of knives, I cant figure out what is missing? In my years of collecting knives my taste have fluctuated greatly, yet it still seems as though something is missing. I can't seem to put my finger on it and it is driving my crazy. While the most expensive knife I have purchased was around 650, I am quite certain paying more is not what I am after, but something else? As a knife guy, we are always chasing the next purchase, but I can't seem to figure out what is next on the list? While I would not like to see this thread turn into an arena for fanboys to fly their flag, I would like to use this as a place to discuss the philosophy behind what makes the perfect knife or maybe some theories into what makes the perfect knife and if anyone has hit that brick wall in their knife career.
