To use a repair kit in Indiana Jones and the Great Circle, follow these detailed steps:

### Step-by-Step Guide to Using Repair Kits

1. **Locate Repair Kits**:
– Repair kits are small gray boxes that can be found near benches or inside enemy camps. You can pick them up by pressing the corresponding button on your controller to collect them. You can carry up to ten repair kits at a time.

2. **Open Inventory**:
– Press the right button on the D-pad to open your inventory. On PC, press the Tab key to open the menu.

3. **Select Broken Weapon**:
– In your inventory, find the broken item. If it can be repaired, a corresponding icon will appear next to it. For example, if you have a broken revolver, you will see it snapped in half in its icon on the left side of the screen.

4. **Use Repair Kit**:
– Select the broken item, and a repair option will appear at the bottom of the screen. By default, the E key is used if you have a repair kit on PC, and X is used on console.
– Once you select the repair option, press E (on PC) or X (on console) to use one of your repair kits. The number of repair kits in your inventory will decrease by one.

5. **Verify Repair**:
– After repairing your weapon, its durability should be restored, allowing you to use it again as a firearm or melee weapon. The durability is indicated by dots in the lower right corner of the screen.

### Additional Notes

– Only specific items tied to your current disguise can be repaired. For example, when you are in your standard adventuring outfit, you can repair your revolver. When disguised as a worker in Giza, you can repair a small shovel.
– Improvised melee weapons like sticks or batons cannot be repaired. Once they break, Indy will drop them.

By following these steps, you can effectively use repair kits to keep your primary weapons operational throughout the game.
