Introducing the Master Kuo G5 3XL Taiwan Tuna Knife, meticulously crafted for the precision tasks of beheading large fish and expertly sectioning them into steaks. Its unique design facilitates an effective technique—initiating the cut by pressing the heel of the blade into the fish, followed by a smooth rolling motion to complete the task. The gracefully curved blade also excels at making extensive lateral slices.
