My cabinet saw has plenty of power but I still use a thin kerf blade. Only time I use a full kerf is when I use a flat top grind blade for joinery.

Using a full kerf blade just wastes wood. There is no reason to use them unless you already have them and don t want to buy a new blade yet.

I really don t buy the whole “FK is more stable” thing. If you have to push the wood so hard it s making your blade deflect then your blade is dull or something else is FUBAR.

Roland Johnson from FWW did an article on this a few years ago. I believe he found no difference in terms of deflection between thin and full kerf blades.

I do…..Seen a lot of warped blades thin and full….
