I originally started out wanting a knife simply for the ooh feature. Shiny metal that just looks so pretty.
My first choice was a Benchmade 740 Dejavoo. G-10 handles, S30V steel, modified locking liner. It looked so ergonomic and pretty. For $105, I thought it was a steal compared to the $160 it retailed for, so I picked one up. It fit so well in the hand and was very easy to resharpen, which I liked.
After I played around with that knife for a while, I got kind of tired of having to retighten the pivot screw every week so I went and picked up a Spyderco Caly3, which was the other knife I had wanted to buy at the same time. It was a wonderful knife in VG-10, relatively small and not very menacing. The profile of the knife was ridiculously thin too. Oh, and the leaf blade was just perfect for slicing, which is what I usually need in an EDC, so it worked out perfectly. However, I still felt some disappointment in my purchase.
As time went on, the Caly3 just didn't seem to fit what I wanted. Sure, it was great and did everything that I needed, but something was just missing. I eventually gave it away to my girlfriend's brother (which is a steal for him, since it set me back over $100) and off I went to find another EDC. In came a Cold Steel Ti-Lite 4" with zytel handle, but it wasn't much for slicing as much as it was for stabbing. Next came a Swedish mora from Frost's of Sweden, which I still use to this day, as it's a cheap fixed blade that I can simply abuse, and for $12, why not? However, it just can't be carried with me everywhere, as Californians tend to shy away from people carrying weapons in plain view.
Finally, after doing much reviewing, I've settled upon my EDC folder that will probably stay for years to come. I went and picked up an Opinel #8. Carbon steel blade, very thin, hardwood handle, and a simple pivot ring to lock the knife both open or closed. The best part is that it only set me back about $10, which means I'll probably pick up a few more just to have around.
So, I guess you could say I started out buying into some of the big-name hype companies and worked my way towards more traditional knives. Seems like the simpler the knife, the more useful it is.
