The use of a splitter or riving knife will all but eliminate this issue if proper technique is followed....forward pressure, downward pressure and pressure inward towards the fence.
I just don't agree with this statement. Is the statement to read ..."will all but eliminate", or, "will eliminate"? Not very clear. I'm reading it as that those two devices will eliminate the kickback issue...which I don't agree with.
While those two devices are intended to keep the kerf, wood can "walk" as it's being cut. Wood can, push against the fence towards the blade. In a case like that it's edge can be forced into the riving knife or splitter, and cause binding. What happens then...since it's at the rear of the blade, can be projected up and forward towards the operator.
This is the same complaint I have with the "short fence", that is used in Europe. Makers there decided that once the stock clears the back of the blade, it needs no fence, and hence, lessens the possibility of kickback. BULLPUCKY. As wood gets cut, it can drift either way. So, for example, if ripping a long piece of lumber, with no fence past the blade, you have "legs" as a result of the cut that can go anywhere.
