Has anyone used this Gingher sharpening service? https://gingher.us/Gingher_Mainte...

My Gingher 4 inch curved embroidery scissors need sharpening and I want to be sure about the service before I send them out. I purchased a new pair to have an extra and it's made differently now with a thicker lower blade which makes it so I can't cut as close. That's why it's important to fix my old pair. My local scissor sharpeners won't touch this type of scissor.
