Do the knife yourself

For centuries, the knife was an integral part of every man's equipment. Nowadays, the ability to make a knife is not less actual than several centuries ago. In this video you will learn how you can make a knife with your own hands, which can be used both in everyday life and, if necessary, for self-defense. The knife produced in this way will be unselectable, i.e. awkward, which on one hand makes it difficult to wear safely, and on the other, allows you to instantly gain an advantage in an unexpected attack by lightning-fast extraction and alerting.
