Finding a craftsman who can make a concealed weapon requires caution, as such requests often involve legal and safety issues. In many countries and regions, the making and use of concealed weapons may be subject to strict legal restrictions. Therefore, it is important to ensure that your request is legal and in compliance with local laws and regulations. If you are interested in weapon making or ancient skills, you can consider the following legal and safe channels: 1. **Historical reenactment or martial arts clubs**: Some clubs may have in-depth research and legal demonstrations on the making and use of traditional weapons, and you can learn legal knowledge through these clubs. 2. **Craft markets or artisans**: Look for craftsmen who have experience in metalworking or replicating traditional weapons. Often, these craftsmen will create works for the purpose of cultural inheritance and display, rather than producing weapons that can be used for attack. 3. **Museums or educational institutions**: Some museums or educational institutions offer exhibitions or courses on the history and craftsmanship of traditional weapons. No matter which channel you choose, please explore and learn in a legal and responsible manner.
