Which nail shape is considered the weakest?

The pointed or stiletto nail shape is considered the weakest among the options. This design features a narrow, elongated tip that creates a dramatic and fashionable look. However, the structure of pointed nails leaves them more vulnerable to breaks and splits compared to other shapes. The tapered end does not provide the same level of support as the broader tips found in square or squoval shapes, which distribute stress more evenly across the nail.

Additionally, while round and squoval shapes offer a more balanced structure, allowing for greater durability and less likelihood of injuries or breaks, the stiletto design, due to its sharp point and minimal support at the tip, is prone to damage, especially in day-to-day activities.
