Yup, safety first. I've got my Grrrrrrripper, and use it. But, I also use push sticks and push blocks a lot - all homemade. But when I start something new, usually cannot find either a push stick, or push block, but always find my Grippper, but not always my first choice. So every time I make new push sticks and/or push blocks, out of leftover pieces. Because if I can't find any, they are usually so chewed up by the saw blade they aren't something I want to reuse.The alternative as the piece gets thinner and thinner is a long, skinny push block. The pictures are of a variety of push sticks and simple shop made push blocks, any of which will increase safety.
Works for me.
