common sense is the KEY to using a RAS (or any saw for that matter). Always stay clear of the blade, NEVER take your hand off of the carriage handle when the blade is spinning (unless its locked down), and always be aware of direction of rotation. Most RAS injuries happen because the opperator is ripping a sheet of lumber and is unaware of which side of the saw is infeed or outfeed.
That said, a RAS is one of the most versitile tools you can have in your shop. various types of cutting, various types of sanding, dado cuts, boring and drilling, light router work, etc. etc..
Just remember, as much work as you can do with a RAS, they will still go through your body like a fart through pantyhose.
And yes, they are being phased out. Mainly because people who have no buisness owning tools of any kind hop on them like they're a toy. Too much liability.
There was a video on youtube of a woman cross-cutting some boards on a RAS. They were bragging about how good they were at using the saw, blah blah. In the video, she had the saw all the way OUT twords her, was placing the boards next to the fence with the saw ON without a hand on the handle, and then SHOVED the saw backwards to make the cut. I left a comment about how lucy she is to have all of her digits and/or her apendages and the video was pulled.
Those are the kind of people who are getting great tools like this removed from the market.
