OK. I'll answer my own post. I'll limit it to 5 must have knives (at some point) for any knife enthusiast (in my opinion of course).
1. Opinel (7 or 8) - Knives are for cutting things, and nothing cuts like an Opinel. Besides, they are ultra cheap and cool
2. Any compact but not tiny SAK
3. Delica 4 - arguably the greatest EDC knife of all time in terms of balancing functionality, size, and weight
4. Paramilitary 2 - Well, because it's a PM2, and is great for a super wide range of uses
5. Dragonfly 2 - because it's the epitome of the small big knife. Very few folders are as light and easy to carry, yet have the fast and easy deployment plus utility of the Dragonfly.
If I had to pick just ONE of the above? It would probably be the SAK, but the SAK cheats a bit because it is a multitool. For just a knife? For me I would pick the Dragonfly 2. The blade geometry for slicing, the weight, the surprising utility for such a small knife, and its non-threatening nature make for the ultimate package for me, as well as one knife every knife enthusiast should own.
