Figure N10.01: Shown on the right is a cast-off blade from my miter saw. It's 16" x 2", and, as illustrated, really flexible.

Scrapers are cognizant Makers' secret weapons in the battle for smooth wood. Why they're not standard-issue equipment escapes me. The Fox Mulder in me suspects collusion between an army of mutant mind controllers and the Sandpaper Industry. Trust no one . . .

Once you get comfortable forming the hook, you'll never look back. I learned the process about 20 years ago from a community access cable TV show. It took me about 10 minutes practice to suss out exactly the right angle and pressure needed to form the hook. Your learning curve may vary, but here's the basic process.
