What table saw blade do you use for splines?

I use one of the outer blades from my dado set. It is 1/8” wide and leaves a flat bottom.

I use one of the cutters from my stacking dado set. I’m too cheap to spring for a regular flat kerf blade.

You can also do it on your router table with a slotting bit. I realize that you asked about a table saw process, but this is another option.

I use a flat grind on a Freud rip blade too.

FTG rip blade. A flat top grind is the only grind that’ll leave a truly flat bottom.
