Preventing Cracks with Salt: To prevent cracks, soak a new walnut cutting board with handle in concentrated salt water for 12 to 24 hours, then let it dry. Additionally, you can use a suitable metal band to tighten the board and close any existing cracks.

Daily Use and Maintenance: Proper daily care is also important. Clean the 3 piece bamboo cutting board set promptly after use and avoid exposing it to direct sunlight to prevent drying and cracking.
