This. Thug and Punk is about it. Tough carbon steel. Full tang construction. Flat grind.
I don't think any other Buck knives offer that combination.
IME, grind really matters. I would rather process game with a flat/sabre ground blade than process wood with a hollow ground blade.
This is the disconnect with Buck and the survival/bushcraft market. Buck primarily focuses on hunting, and with that, is more focused on hollow ground knives. My sense is that the design of the Thug and Punk was completely driven by Hood. Buck hasn't seen their way to pull the design elements through to other designs.
It would be excellent to see Buck use more flat ground and drop point blades in both their folding and fixed blade lines, but until then, they offer very little that compares to knives like the BK2.
