jaw saw..bar is hidden until you have the branch grabbed, and that takes two hands. You would have to go out of your way to get a kickback with it, and even then, the bar is still inside the protective jaws. .
This is absolutely about the safest chainsaw thing made. You can cut small firewood and kindling with it. No sawbuck needed, nothing. No dangerous holding something with your foot to cut it. No gadget branch holder needed, store bought or home made, just this saw. You can reduce a random pile of branches, say 3 inch and under although it will cut a bit larger than that, to 100% cut to size usable firewood. I've done it, it works, it is a spiffy design.
