Thin-Kerf Blade Needs Thin Riving Knife
Len Jankis, Norman, OK
Yes. The riving knife should be as thin as or thinner than the kerf of the blade you plan to use. If it’s thicker than the blade’s kerf, then boards will get jammed on the knife, creating a dangerous situation.
The good news is that most tablesaws equipped with riving knives offer a thin-kerf knife as either standard equipment or as an accessory.
