I have been using scythes perhaps 15 years less than you have, but I found that when using the old shape stone, I would not grab the stone like a handle. I found that it was far safer and easier to grip the sides of the stone such that when I finished the edge feather, I could slide the stone upward and not get my skin anywhere near the sharp edge. I also did my initial sharpening runs from back edge toward the front, but find my final edge is sharper if I finish with an upward stroke diagonally along the edge. Fingers and knuckles are always safely back on the stone. If one was worried about slight slices, they could also purchase some butcher knife-proof gloves.
Maintaining close attention to what one is doing, of course, is the best practice. Sharpening a scythe is not a multi-tasking situation.
" find my final edge is sharper if I finish with an upward stroke diagonally along the edge" Agree. It may not be clear but in each direction the stone is held at an angle to the travel starting with the meddle of the stone and ending with the tip at the end of the stroke. So the stone is traveling up against the edge.
If the edge is very sharp and thin it may curl over the bottom and not cut very well. To check for that the flat side of the stone is run flat on the bottom edge with very little pressure just feeling for any drag that will be caused by a back curl or nick. Avod making any bevel on the bottom edge because that favors the the blade sliding up the stalk of grass instead of cutting in.
