Unfortunately all sold before I got there! I would have snapped it up.

Your analysis seems correct. However, the last recommendation for Hi-ATB was from a blade sharpener.

It is unclear if Infinity and Amana use different metallurgy in their tips from blade to blade. Both seem to spec C-4 submicron carbide. However, Freud lists 7 different tooth metallurgies. The Hi-ATB Plywood blade and most of the other wood blades are the middle grade. The laminate/melamine and solid surface blades are the hardest using a micrograin 1/2 the size of C-4.

The question then is also will the different metallurgy help reduce wear? If so, do other manufacturers do it?
