I have stopped buying folding blades this year yet still maintain the obsession with them, and the Military is the reason. I cannot see the necessity anymore in "searching for more". The grass stopped being greener when I found myself lusting for multiple variations of the same model, and the carbon fiber M390 Military sealed my deal.
Spyderco maintains, IMO, their market presence not based on hype or advertising or anything else, it's all word of mouth and pure function. The first time you EDC a Spyderco of any model and realize that the materials, steel, and fit and finish are beyond that of any other knife that comes off a production line (even given a wiiiide price range) you are hooked. The huge number of very knife savvy people that agree are a testament to this.
Everyone has a particular taste but I would be hard pressed to not find something in the Spyderco line up for every and anybody. If it works, it just plain works. I would emplore anybody bitten by the Spydeco bug to delve in further. It only gets better.
