Unsealing and Polishing Process for Wood Cleaving Knives#shorts

This process involves specialized techniques to prepare a new wood cleaving knife (柴刀) for use by removing factory-applied protective coatings (unsealing) and refining its blade edge through successive grinding and polishing. It typically uses progressively finer abrasives—from coarse stones to fine sandpaper or honing steels—to shape the edge geometry, eliminate burrs, and achieve a sharp, durable cutting surface. The craft emphasizes maintaining the blade’s original angle, ensuring uniform sharpness along the edge, and creating a smooth finish that reduces friction during wood-cutting tasks, enhancing both efficiency and longevity of the tool.
