This is a Nanchang slicer (boning knife). The blade length is approximately 25.5cm. It is single-edged. The steel type is unknown. It is made of all steel. The back has the inscription "刀都作" (Katana Tsuku). I previously listed this item, but there were several rough scratches on the flat and back surfaces caused by power tools, so I repaired them. I also polished out minor scratches and made it mirror-finished. There is a small crack at the end of the handle, but I don't think it will progress. After polishing the handle, I applied beeswax, so it should be less prone to dirt. I recommend it if you don't mind. While it's a boning knife, it can also be used for sashimi and skinning fish. Nanchang boning knives are popular, so they sell quickly, so don't delay. Both the cutting edge and the flat surface are almost mirror-finished. It is also lightweight and generally clean, so I think it can be used for a long time. It is recommended for both professionals and general households due to its size. The sharpening stones used were Kitayama 8000 grit, Shapton 12000 grit, and a natural whetstone. It is in a very sharp condition, so you can use it immediately. ● Size: Blade length approx. 255mm ● Thickness at the thickest point: approx. 1.7mm ● Overall length: 375mm ● Weight: 167g #Knife #BoningKnife #Nanchang #25.5cm
