Just curious - It is still sharp but when it comes time, I want to know what I'm doing. I have a card scraper which I sharpen with a file, then burnisher but this one is curved. I've also got a scraper like this one but inverse.

carefully.....
But seriously, I would use wooden dowels and an assortment of abrasive papers. Then use the burnisher to turn the bur.

You can get round stones of various diameters, both concave and convex to sharpen it, but I don't a correct way to burnish it, or if you should for that matter.

For what it's worth, I have one of those and used it maybe twice (on cherry). What I did was to hone the flat sides on a fine ceramic stone (any fine stone would work) and then used a carbide burnisher to turn an edge. It worked, but I had to have a good grip on it otherwise it had a tendency to skip.

you could try using dowels with sandpaper attached to them.

Dowels with polishing compound (Jeweler's rouge).
If you're deforming the edge, you're turning ebony pegs.

I don't use a file for scrapers. I use my diamond stones an get the edge square and polished before going to a burnisher to form the hook. That's all I'd do if I wanted to use the convex edges.
For the concave parts, I'd use sandpaper and a dowel. It's a cheap and easy way to get the edge prepared for burnishing. I'd also probably use a nail set to for the edge. The thin tapered shape would work well for this application.

What do you mean?

So, I thought to sharpen *any* scraper, you need to:
1)file the edge square
2) hone the newly filed surface
3) burnish
Is that right?
By the way, thank you all for the input!

The edge should last a long time, if you're trimming softwood dowels.
If you're deforming the edge quickly, the material is very hard.
Ebony is very hard.
