What to consider when buying the best credit card knifes

Credit card knives are designed to be portable, lightweight, strong and durable. Whether buying them for safety purposes or opening packages, credit card knives remain the newest thing for both men and women.

However, before buying one, here are a few things you need to consider to get the very best:

  • check
    The blade metal: The blade metal determines the quality of the credit card knife. Don’t compromise on quality for portability. When it comes to blade metal material, go with knives made of stainless steel and aluminum. The blade metal should be rustproof.
  • check
    Length of the knife: Folding knives length usually starts from two inches and go all the way to 6 inches. Depending on your need, choose the ideal length that will fit in your pocket and wallet. The ideal credit card knife length should be from 2-3 inches. The knife will be kept in your wallet so the smaller, the better.
  • check
    Safety lock: Locking mechanism of credit card knifes is crucial as it determines the safety of the knife. The lock must hold firmly but also be easy to open and fold. The locking mechanism is important as most credit card knifes lack a protective sheath. A smooth locking system ensures your safety and those of children around the knife.
  • check
    The handle material: Most handles are made of the tough ABS plastic materials and tend to be cheap. However, this is not the best handle material as it gets flimsier with time. Go for the titanium coated stainless steel handle. Wooden handles are also great but get slippery when wet.
  • check
    Price: Price should be your final determining factor. Credit card knives are cheap, and one doesn’t have to pay a lot to get one. Consider your needs, budget and get a knife that is fairly priced with features matching the price.

Based on the above considerations, we have searched the internet and come up with a list of five best credit card knives available on Amazon for sale. These are the best picks currently and retail at a good price giving consumers a reason to buy. Let’s have a look:
