Forgive my ignorance on blade grind geometry but wouldnt a full convex grind be best with this thickness? Would bring it closer to a hybrid machete/chopper? I would guess that would bring the cost way up on them though. Maybe if the coating ever gets to ugly it would be worth trying. All speculation of course. I kinda like the extra beef, dont need to worry about what I sink it into.
As far as I know the only way to put a full convexed grind on a knife is to do it by hand. Obviously this would take far more time and effort thus substantially raising the cost.
