The appearance details of this knife highlight its outdoor practicality, as follows:

- Blade: Made of stainless steel with a gray matte coating (anti-reflective and corrosion-resistant), the blade type features a "plain edge + serrated edge" combination design. The plain edge is used for regular cutting, while the serrated edge is suitable for cutting ropes and sawing small dead branches. The blade also has long strip-shaped grooves (which serve both to reduce weight and assist in chip removal), and the pointed tip structure of the blade enhances piercing ability.

- Handle: The main body is made of black engineering plastic with anti-slip texture, with a fluorescent green decorative block embedded in the middle (easily identifiable in outdoor scenes), and the decorative block has a fixing hole. The tail of the handle is equipped with a black lanyard and a buckle, and the overall grip is anti-slip and fits the palm.

- Sheath: Made of gray hard plastic, with a black webbing strap and buckle, it can be stably mounted on a belt/backpack, offering strong portability.

- Supporting tools: The attached small black tool (with serrations on the head) is most likely a flint for outdoor survival, assisting in making fire in the wild.

Its applicable scenarios are concentrated in the outdoor field:

- Camping/hiking: The plain edge can handle ingredients and cut materials, and the serrated edge can cut ropes and saw small dead branches, suitable for daily camp operations;

- Outdoor survival: The matte blade has good concealment, the anti-slip handle is suitable for wet and slippery environments, and the supporting flint can assist in making fire in the wild, making it suitable for mild survival scenarios.
