An entire set of curved scrapers costs the same or less than a box of sandpaper. The difference is that the scraper can last for years, or even decades, and doesn’t fill up your lungs with carcinogenic sander dust. Though the above curved scrapers are identical in appearance, they are of two thicknesses. The .04mm ones are for fine scraping, and the .06 are for more heavy duty work.
At the top right is the famous Bahco/Sandvick scraper. Comes ready to work, and can be used without burnishing. It’s thick for a scraper, at .08mm.
The scraper bring grabbed by the old Stanley #82 is a mystery, as the calipers say it is more than 0.1mm thick. It’s as stiff as a plane bade, and has prepared, aka beveled edges, on two ends, German style. it will make some serious shavings.
A typical burnishing setup includes a vise, and a metal working one is best. An absolute must is a good file, and sharpening stone. A carbide burnisher makes things much easier, and I have a great one that was made by Lee Valley Tools in Canada.
Scrape away. Your lungs will thank you.
