Full flat grind has its place, but with better steels than ever and greater emphasis on thinness BTE, we can do even better with a good high hollow grind.
The GB2 with its high hollow grind is a sheer delight to use, zipping through materials like nobody's business. The Dragonfly Salt also cuts way outsize its footprint, which I feel is thanks to great ergos and a high hollow grind.
I would love to see high performance variants of existing models with a really thin HHG.
Apparently Sal's already ahead of us, but I'm interested to see who else is hot for the HHG?
