You are directionally correct but the top of the line chisels are in fact hand made in Japan and I suspect the same for knives. Lee Valley and some other higher end manufacturers make some damn fine chisels but chisels are hand tools and I would guess 9/10 woodworkers who use chisels will choose hand made Japanese chisels over any factory manufactured tools.

Isn’t the main thing that makes a chisel better or worse the material quality, such that regardless of whether it is hand made or factory made, the chisel made of superior material is better?

Selection of metal, lamination, presence of a ura (裏), handle material, the ability to make a new handle and attach it to the original metal. A metal chosen for an extreme sharpness may be terribly difficult to sharpen, a metal easy to sharpen may not hold an edge for long.

Most factory chisels are not laminations like hand made Japanese ones are. They are just a single alloy.
