Has any-one used these and are they worth getting?

Well, my coach just got them, but I don't know if she's used them yet. She's a Gold-level skater.

I have heard that they are sometimes difficult to sharpen. Make sure that whoever is sharpening them is experienced and understands the specific characteristics of the blades.

They're supposed to be sharpened just like a normal blade. I'm not sure how that works, but that's what our sharpener says.

Everyone I know that has them seems to like them. I'm looking into them for my next blade.
