Hollow grinds seem to have worked well for Buck for a long time now. If it's ain't broke, no need to fix it. Folks that think other grinds are better, should just buy the brands that use the grind that they like.
What kind of grind did Ron Hood specify for the Punk and why?
IMO hollow grinds make perfect sense for hunting knives so its perfectly sensible that the majority of their line. But for knives sold as good for general purpose outdoor knives or survival knives? Hood got it right. Buck can too.
