| Abstract: | Objective To analyze the marks on the concave surface key. Method Samples of manipulated keys and keys that used as guide in a duplication process are made. Marks and striations on the keys are photographed and analyzed by light microscopy. Result There are distinctive marks on concave keys when normally used and when used as guide keys. Conclusion The examination of a concave key can reveal distinctive marks whether the key has been used as a guide to create another key. |
