Ah! Based on your description, the “mysterious” U-shaped tool with a wooden handle you found is likely a charcoal iron—a traditional clothing iron used before electric irons were common. Here’s the breakdown:
🏺 Charcoal Iron: How It Works
1. Structure
- Metal body shaped like a traditional flat iron
- Hollow inside to hold hot charcoal
- Wooden handle to avoid burns
- Sometimes a latch or door to add/remove charcoal
2. Function
- Charcoal is lit and placed inside the iron
- Heat from burning charcoal presses clothes flat
- The metal soleplate distributes heat evenly
3. Why It Looks Strange
- U-shaped or bulky appearance comes from the charcoal compartment
- Wooden handle and heavy metal body make it different from modern electric irons
⚡ Fun Facts
- Used widely before electricity was common
- Still used in rural areas or for traditional clothes that need high, consistent heat
- Some are now collected as antiques or decorative items
✔️ Bottom Line
Your grandmother’s tool is a classic charcoal iron, a fascinating piece of history in laundry and textile care.
It’s functional but also a cool vintage collectible!
