Cutting a nail tip with any tool other than a professional tip cutter will weaken it and cause it to....

When a nail tip is cut using tools that are not specifically designed for that purpose, such as a professional tip cutter, it can lead to an uneven cut or damage to the structure of the nail tip. A professional tip cutter is designed to create a clean and precise cut, which helps maintain the integrity of the tip. Using improper tools can result in stress or weakness in the material of the nail tip.

This weakness can cause the tip to crack, especially when subjected to regular wear and tear or stress from activities. This is because a poorly cut tip lacks the necessary support and structural strength, making it more susceptible to fracturing under pressure. Maintaining the correct cutting technique and using the proper tools is essential for ensuring the longevity and durability of nail enhancements, hence the connection between improper cutting and cracking.
