- Innovative, unique and creative
You are the smartest one. Innovation is the powerful tool for you. You tend to bring more inventive ideas and give attention to the details which might be ignored by others. People with an inverted triangle shape are a little obstinate.
- Assertive and ambitious
If you have the sword-shaped nails then you are most ambitious one. People with this shape are very hard-working and clear. No one can stop you from attaining your goal. Only thing distress in you is that you set a high standard for others. So, work on your team spirit and understand others.
