What do you make your scraper from?

Cabinet scrapers are not that expensive, but I have had good luck just filing straight the end of a putty knife and rolling a burr on one edge, you don’t need much. Putty knives are not that hard but will hold and edge long enough to scrape a pair of horn scales smooth.

You can even file to a curved shape and roll a burr, but not really needed, sandpaper will smooth out transitions easily. Nice tip, great post.
