Fixed blade - Schrade 165OT Woodsman, if you have one, you know what I'm talking about. A very underated "classic" knife.
Folder - Case 6375CV large stockman, a real handfull of traditional slipjoint. The 8OT is a very close runnerup in this category, but I do love the 75 pattern.
How about a multitool?
For me, the best everyday tool I've used so far is the original SOG Pocket Powerplier. Everything I need and nothing I don't in a very smooth, easy to carry package. I've tried others over the past decade, but this model always gets the most carry time and use. Once again, a underated classic design.
