OK from what i understand, a riving knife is attached to the elevation mechanism of the blade. Right? My saw has a splitter built into the gaurd that does the job, so what is all the crave about riving knives?

Riving knives and splitters essentially do the same job, but a riving knife is a more elegant solution. It sits in closer proximity to the blade, and tilts, raises, and lowers with the blade. More importantly, the vast majority of stock splitters are cumbersome, and are more likely to not be used at all. A riving knife is more likely to be in position to do it’s task because it can stay in place for more functions without interfering. There are some aftermarket splitters that are nearly as good as riving knives, but they’re set at a fixed height.

I see a riving knife as a better mouse trap, but it’s not the end-all be-all panacea that some would have you believe.

The riving knife also has the advantage of staying just below the blade top allowing through cuts at any blade height. Saw a thread the other day, need to find it again, that said the knife would not allow non through cuts. This is not the case with a riving knife, it can be set above or below the top of the blade arc allowing the knife to stay in place while making kerfs, full dados or rabbets, etc. I’m certain mine saved a huge kickback the other day when I bound the trail edge of a panel.
The knife changes out easily for kerf width and height along with staying in close to the blade to do the job intended. Sorry for rambling, BTKS
