There are jigs and tools that make them far easier to sharpen. But you can also put thm in your workbench clamp, using a file or diamond stone, and a burnisher (my brother gave me his, made from a good screwdriver). I also bought a Veritas scraper sharpener, which really makes putting the burr on, a predictable and pretty easy job. You can set the sharpening angle quite precisely. The other picture is a scraper holder for those of us who find it hard to hold the scraper properly for any length of time. Do put a burr on all four edges. Forgot what brand, but look up card scraper holder and you'll find several.
The more I do, the less I accomplish.
