Using your Boldric BOCKR115 knife bag is a breeze. First, open the zippered utility pocket to store small items like sharpening stones or extra utensils. Then, carefully place your knives in the 9 pockets provided, making sure they fit snugly. Adjust the shoulder strap to a comfortable length and you're ready to go. When it comes to maintenance, use a damp cloth to wipe down the canvas exterior regularly. Avoid using harsh chemicals as they may damage the fabric or the leather details. If the bag gets wet, let it dry naturally in a well - ventilated area. Also, be careful when inserting and removing knives to prevent any damage to the pockets. With proper care, your knife bag will serve you well for a long time.
