There is no best EDC knife. It is all about personal preference. Ive always loved knives since I was a kid in cub scouts, but didn't start getting serious into them until a couple years ago. I've owned many knives. I have sold many, and bought new ones to replace them. I've owned Kershaws, Spydercos, Bucks, CRKTs, etc.

However, recently I found a knife that I personally love over all my others. It's a Ontario Knife Company Rat I. They usually run about $30, but I got mine brand new for $5 due to a mismarked price tag. It is now my EDC, and never leaves my pocket. It has satisfied my addiction to knife buying as of now!

I was a USA made only guy for a bit, but I learned a knife can be made anywhere in the world as long as the quality control is good. Good luck in your searches!
