To maintain the quality and performance of the Master Kuo G-4 M Taiwan Tuna Knife, it is recommended to hand wash it with warm soapy water. Towel dry the knife immediately after washing.

Avoid putting the knife into the dishwasher, as the outer stainless steel will not rust but the exposed SK5 Core bevel may show signs of light surface build-up over time. Regular sharpening and stropping will help maintain the knife's edge. Additionally, the use of Camellia oil is recommended to protect the blade.
