I have been reading up on Riving knifes for a while. My understanding is that they are permanently installed and can’t be removed – correct me if I am wrong.

Despite it’s anti kickback features, can anyone think of any woodworking situation where a riving knife would either reduce functionality of some operations of a table saw? Either that or just cause problems in some situations?

If money was no object, would you buy, or avoid a table saw with a riving knife?
