There are indeed some antique weapons that can be designed to be disguised as ordinary tools. Here are some examples: 1. **Swords and knives**: Some ancient swords or daggers may have very exquisite decorations, and look like decorative works of art or crafts. Some can even be made into knives that can be hung on the wall. 2. **Crossbows**: Some antique crossbows are compact in design and may be disguised as ordinary tools, such as hunting tools, and sometimes look similar to modern tools. 3. **Axe**: In addition to being a weapon, ancient axes were often used as tools. If the design is appropriate, they can be confused with modern farm tools or gardening tools. 4. **Cane swords**: Some canes have sword blades hidden inside. This cane looks ordinary, but it is actually a hidden weapon. 5. **Umbrella swords**: This umbrella can also have a sword hidden inside. Although it is not common now, it has been used in history. 6. **Small throwing weapons**: Such as darts or small slingshots in the hand, some designs can make them look like ordinary toys or tools. These weapons usually have certain historical value and collection value, and need to be treated within the appropriate legal and ethical framework. In any case, you should be aware of local laws and regulations before possessing or displaying these weapons.
