The FN Big D-12 Heavy Duty Bone Cleaver is hand forged from spring steel with a traditional wooden handle and a rat tail tang. Weighing in at 780 grams or 1.75 lbs. it is a serious butcher knife for chopping through bones. The edge is hardened to Rockwell 60 and features the protective scale coating from forging to give it that more rugged, rustic, and all around more manly look. It can easily be swung all day by the rough traditional wet market butcher, the surgical chef, or the random crazed mass murderer.


  • Blade: 180 x 100 x 6 mm / 7″ x 4″ x 0.25″
  • Handle Length: 100 mm / 4″
  • Overall Length: 285 mm / 11.25″
  • Weight: 780 g. / 27.5 oz. (1.75 lbs).

Knife care: Keep clean with warm water and soap. Towel dry immediately. Do not put into dish washer. The edge steel can show signs of surface rust over time. Most surface rust can be removed by sharpening the edge or using a scotch brite pad.

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.

The FN Big series is a collaboration effort between Jende and Master Kuo. 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

  1. Rhett

    Forged cleavers always seem to have a better feel to them than mass produced ones. This thing just looks and acts tough.
