I've got a Grrrrrripper (however you spell it), and like it. Won it, didn't buy it. I'm 77, started out helping my grandfather when I was probably 7 or 8. Started using power tools in 9th grade, table saw in 10th grade. No riving knife or kick back thingies on my saw. Never had a kickback yet, and don't plan on having one. BUT, just in case, I always stand out of line with the blade. Learned that one in the 10th grade, when our shop teacher demonstrated kickback, and described what caused it. And I still remember that piece of wood hitting the wall. Unless I am holding a piece of wood well away from the blade, I use push blocks, not so often push sticks. I set my blade so it just cuts the top of the wood, then use a push block, with a handle, thick enough that I can pass right over the blade and it will just make a very small cut on the bottom of the push block, and impossible to cut me. It helps to be a bit scared of the saw, or anytool with whirly parts that can bite you; it make you careful.
You see pictures and videos of people standing in line with the blade of a saw, a lot of time supposedly skilled woodworkers. Which just about guarantees that if there is kickback, they are going to get hit. Standing out of line with the blade is one of the best safety measures you can take with a table saw.

I am currently unsupervised. I know, it freaks me out too. But the possibilities are endless!
Call me a craftsman, artisan, or artistic, and I will accept that. Call me an artist and you will likely get a quite rude comment in return. I am not a @#$%ing artist.
