I thought a heavy push block would give me control so I used this piece of Oak for a while, till it flew past my head.

One way kickback happens is the workpiece is allowed to lift above the table by a little bit, then gets sucked down into he teeth which can launch it. That happened to my push block because it was longer than the workpiece.
Now I use this block, shown here in oops position. It is a big block of Balsa with an Oak tab on the back and a Pine handle on top. It's immune to this particular mistake, and it's a terrific push block. I made one for a friend with foam instead of Balsa. Works great, just be careful what glue you use. 4" x 6" x 24"

Here I am using a thin side push stick to hold the work against the fence.

The attached thumbnail shows a push stick in a position to get driven into my hand. Not recommended.
And I don't let any plastic or metal onto the table for fear of shrapnel.
