I was sharpening a curved scraper this morning and that’s a finicky thing at best. I was wondering what method others use for this process? I end up with a tool that works well. I thought you all might have some “speed” secrets to share.

I don't know if this would apply to your situation, but I use curved scrapers a lot on wood turnings, sometimes with the wood moving but more often used as a normal scraper.Quote:

Some of my curved scrapers. I grind new profiles as needed with a 1" belt sander - far cooler and easier to control than a grinding wheel.

If you end up with a tool that works well please share your method!

On my curved scraper the goose neck style I clamp a flat file in my tail end vice then rotate the scraper as it sits flat. For the inside curve I use a round file. Then use the burnisher to draw out the hook.
Look for a card scraper burnisher.

Rough shape with snips, hacksaw, grinder and sanding drums. Hone with shaped stones, burnish like any scraper.
nothing special John. I use a diamond paddle, coarse, with the scraper up on a block. I will use a file if I’ve broken out a piece on a knot or something. On the inside curves I use a diamond chainsaw file, fast and cheap. I burnish as you do, down only.Quote:
