In this series, we have upgraded the product design with a new finger protection design. The arc transition at the junction of the blade root and the blade avoids accidental finger touch and cuts during use. In the pursuit of product aesthetic performance, we have never forgotten the practicality of the essence of the knife. The Lan series has achieved the unity of appearance and function. Products in this series is made by 3 layers 10Cr15CoMoV composite steel with a hardness 60±1 HRC with good levels of corrosion and rust resistance and toughness. It adopts the 3 layers composite steel mirror polishing and sandblasting process. Forged from composite steel, the surface is mirror polished and sandblasted to give the surface of the knives an original texture. The knives in this series use pakka wood material for the handles, also treated with high-quality resin, which is particularly resistant to moisture.
