If you have concerns about the knives, it may be best to reach out to Tupperware directly to inquire about their exchange or return policy. **

Folding knives can be used for self-defense in certain situations, but it is important to check the laws in your specific area regarding carrying and using knives for self-defense. In some places, carrying a folding knife for self-defense may be considered illegal or may have restrictions on blade length. It is also important to consider the potential legal and ethical implications of using a knife for self-defense, as well as the level of training and skill required to effectively use a knife in a self-defense situation. **

The best knives for self-defense are typically fixed-blade knives with a sturdy and sharp blade. These knives are more reliable and easier to deploy quickly in a self-defense situation compared to folding knives. Additionally, knives with a blade length of 3-5 inches are generally considered to be the most effective for self-defense, as they strike a balance between being easy to handle and having enough reach to be effective. It's important to remember that self-defense should always be a last resort, and proper training and legal knowledge are essential before carrying a knife for self-defense purposes. **

Knives can be used in self-defense situations as a last resort when facing an imminent threat. It is important to remember that using a knife in self-defense should only be done when there is no other option to escape or protect oneself. If forced to use a knife, it is crucial to aim for the attacker's vulnerable areas such as the throat, eyes, or groin to incapacitate them and create an opportunity to escape. Additionally, proper training and understanding of knife techniques are essential to effectively and safely use a knife in self-defense. **
