The Master Kuo G5 3XL Taiwan Tuna Knife is designed for cutting the heads off of large fish, and for cutting the body into steaks. It is used by pushing the heel of the blade into the fish and then rolling the blade forward to finish the cut. The curved blade can also make long lateral slices.
The curved leaf shape is very handy for butchering large fish like Tuna, Mahi, and Grouper.
The G5 knife is made with 3 layered laminated steel.
The outer layer is stainless steel and the core is made of traditional Japanese high carbon SK5 steel.
Rockwell tested at 60-61 hardness.
Hand wash with soapy warm water. tow dry immediately after washing.
Do not put into the dishwasher, the outer stainless steel will not rust but the exposed SK5 Core bevel can show signs of light surface build-up over time, regular sharpening and stropping will maintain this and the use of Camelia oil.
