3 Strongest Shapes Square: Square nails, with their straight edges and sharp corners, offer a wide surface area that generally withstands breakage better than more tapered shapes.
Oval/Round: These shapes mimic the natural curvature of the nail bed, distributing force more evenly across the nail, which helps prevent breakage.
Tips for Reducing Breakage – Keep them Short: Shorter nails are less likely to break because there's less leverage and force applied to them during daily activities.
