quanto verrebbe a costare

When possible, it is better to disassemble the scissors. Otherwise, the other blade could ding on my waterstones and screw up the sharpening. Nice to take them apart, cleaning, oiling them with japanese shear oil. Doing the tension test., and cut the ONE PLY WET KLEENEX. Not the fabric, not the white paper.
I also do the ride line on a leather strop with 30,000 grit aluminium oxide. and polish it with baby cloth that has 30,000 grit powder ( guitar baby cloth )

@louis2457, I agree with you. For bevel scissors, must be good. I could sharpen bevelled scissors with japanese waterstones. Removing nicks with 1000 grit, getting the edge with 4000 grit, and polishing with 8000 grit. Removing burr with 4000 grit and 8000 grit.
For japanese scissor, this is easy to do with Japanese Waterstones. Very sharp for scissors that never been sharpened but if the scissors were sharpened with bevel angle instead of convex angle, it will never cut good as new.

should disassemble scissors - removing too much metal is not good taking a pair of japanese made scissors to this machine wrecks them. Only good for scissors manufactured with a bevel edge - I repair alot of scissors - I own this machine but use a horizontal double plate unit on most.

Also all I see is metal to metal contact, no water nothing. I use aluminum oxide pads in the 9 micron to 40 micron range and an 8000 grit stone to polish the rideline on the inside of the blade. I did'nt see any of that either.

I use a Schimech. what I want to see is you sharpening a convex style shear. They do not have a bevel like you are putting on in your video.

But here is my dilemma. If I continue to sharpen like this, eventually the hollow bevel will go away. Is there a way to restore the hollow bevel? Like any competent sharpener, I remove the least amount of metal, but eventually I will need to figure out how to restore the hollow bevel. Does anyone have any ideas?

I use very wide, flat surfaces beneath my abrasives to preserve the flatness of the insides of the blades; this ensures that they fit together correctly and maintain contact all the way along the stroke of the cut. the individual blades shaved the hair off of my arm. She said they cut better than when they were new. She gave me all her scissors to sharpen and the other stylists in her shop want me to sharpen their shears as well.

I aloready have a knife and edge tool sharpening business. A friend of mine who is a hair stylist asked me to try my best with a $600 pair of shears she had dropped. I did some research and found that the convex part of the blade is engineered and manufactured to very exact tolerences. All that is needed is a polishing, which I did with a leather strop and a fine compound. The flat bevel on the inside I sharpened for a few strokes with 600, grit, then 800, 1000, & 1200. Finished with strop.
what size grit wheel do you use?Is it the 800 that comes with the Ookami package?
