Using this knife bag is super easy. First, unroll the bag and place your knives and utensils in the 9 pockets. Make sure the longer knives fit well as it can hold knives up to 15 inches long. You can use the zippered utility pocket for smaller tools like bottle openers. Adjust the shoulder strap to a comfortable length for carrying. When it comes to maintenance, keep it away from sharp objects that could tear the canvas. If it gets dirty, you can gently wipe it with a damp cloth. Avoid exposing it to extreme heat or moisture for long periods to preserve the water - buffalo leather details and the waterproof interior flap. Also, don't overstuff the bag to prevent damage to the pockets and the structure of the bag.
