Self-defense: First of all, a knife is a tool. When facing wild animals or dangerous people, it is a defensive tool. If it is not long enough, it can be tied to a long and strong wooden stick to facilitate the opening of the road. Skinning: If fish or hares are caught in the wild, the survival knife can be used to skin or scrape fish scales. Tableware: Forgot to bring a fork outdoors? Or chopsticks? Then use a knife as tableware, provided that the blade is clean enough. Digging tools: If your survival knife is of good quality, there is another use in the wild, that is, as a shovel. Of course there are many more functions.
