To care for and maintain VG10 steel, it's essential to clean the blade after each use, sharpen the blade as needed, and store the knife in a dry, cool place away from moisture and humidity. When cleaning the edge, rinse it under running water, scrub it gently with a soft-bristled brush, and dry it thoroughly with a soft cloth or towel. You can also apply a few drops of oil to the blade to protect it from moisture and prevent corrosion. When sharpening the blade, use a sharpening stone or honing steel and hold the knife at a 20-degree angle. When storing the knife, use a knife block, magnetic knife holder, or sheath to protect the blade from damage.
