The Master Kuo GL 360 Long Taiwan Tuna Knife is a big fish knife with a long, straight blade that is 360mm, or 14″ long and 80 mm or 3″ high. It is used to make long lateral cuts as well as cross sectioning cuts on large fish like Tuna, Mahi, Swordfish, Grouper, etc. The G-L300 looks and acts like a very large chef knife that can cut through fish bones, and is almost always accompanied by a G-5 XLG-5 2XL or G-5 3XL. It is kin to a Japanese maguro bocho.

This blade is stainless steel cladding with a Japanese Carbon steel core, and a stainless steel handle. Hardness is RC 60-61. It is also available in 300mm (12″) and 340mm (13″).
