Can beauty scissors be sharpened with a belt grinder?

[Brent Riggins]

As you know beauty scissors has convex edge.  So to sharpen it, we need WOLFF Hira-To or TAS(& convexing clamp). 

But belt grinder(e.g. Viel, Kally) can sharpen convex edge knives. 

How do you think about it? Is there any problem with sharpening beauty scissors with belt grinder?

I would get a pro to do it. What is going to happen is, you are going to remove some of the material from the blade. If you have a super fine belt and a real steady hand go for it. But I get my hair shears from Kenchii. They have different level shears to pick from and I only sharpen them once a year. Go to https://kenchiibeauty.com/shears/ and pick a level 3 shear, they also have a life time warranty.
