I purchased an amazing and convenient knife from Amazon. I have taken it through airports without any issues, but I am uncertain if that is standard practice. To determine its sharpness, the knife should pass the tennis ball test. If it fails, then a new knife may be necessary.

    I had a scary encounter where a man with a broken bottle demanded that I hand over my wallet. I complied, but secretly retrieved a knife from my wallet and threw the wallet in his face, which gave me enough time to fold the knife. I then confronted him with the knife and he eventually ran off. It definitely saved me from being mugged.

          I recently obtained a couple of knives with a different name on the blade at a Gun Show. The vendor gave them to me along with another purchase. I am keeping one of the knives in a readily accessible place while carrying my wallet in my pocket for quick access in case of an emergency.

            I have bad experience. The plastic used is similar to the one used for LEGOs and is cheaper than what I had anticipated. The card is not sturdy and has folds that do not securely lock, making it feel like a credit card with random hinges on it. Additionally, the blade is not very long. Other than that, the product is good.
