Finding a craftsman who can make a concealed weapon is a relatively complex task. It is worth noting that activities involving such production may be illegal in many areas and there are legal risks. It is recommended that you follow legal and ethical standards and consider the following ways to find professional craftsmen or technicians: 1. **Professional forums and communities**: Some weapon enthusiasts or craft communities may have relevant discussions. You can ask other members on these forums. 2. **Craft fairs and exhibitions**: Attend relevant craft fairs or exhibitions, where you may meet some professional craftsmen. 3. **Social media platforms**: Find relevant hashtags or groups through social media platforms, and you may find some professional craftsmen. 4. **Local craftsmen**: Visit local metalworking or woodworking shops to see if they can provide you with help or recommendations. Please make sure that you always maintain legal and ethical compliance in this process and avoid participating in any illegal activities.
