Using this knife bag is super easy. First, unroll it on a flat surface. Then, place your knives, cutlery, and utensils into the 7 pockets one by one. You can use the zippered utility pocket for small items like bottle openers or sharpening tools. When you're done, roll it up and secure it with the leather strap. For maintenance, keep it away from sharp objects to avoid tearing the canvas. If it gets dirty, use a damp cloth to gently wipe the surface. Don't immerse it in water as it may damage the leather details. Store it in a dry place to prevent mold growth. Always handle it with care to ensure it lasts a long time.
