Master Kuo knives are some of the sharpest factory sharp knives we’ve ever seen, but they are capable of even more after our professional sharpening services. We recommend the 2000 and 5000 Grit services for this knife. You can also add a custom made leather sheath.

Kuo Chang-Shi is most famous for forging the original Green Sword of Destiny from the 2000 movie “Crouching Tiger, Hidden Dragon”. His Damascus steel designs incorporate human bones and ashes to imbibe the spirit into the piece, as well as to add some elemental strength to the steel (such as manganese and phosphorus), which is based on historical accounts in ancient Chinese sword making.

    The wife bought me this knife as a birthday gift. The sheath also had my name custom engraved on it. This is the most pampered thing on the boat now – after my wife!
