When you think about a pocket knife, the most common assumption is that it is a weapon for self-defense. While that is an accurate assessment of the product a pocket knife is more useful than a weapon you may never use in self-defense.

The high quality and well-designed pocket knives Zero Tolerance, a member of the KAI group family, develop some of the highest quality precision pocket knives that are available today. Here are the best Zero Tolerance knives you can purchase.

Criteria Used for Evaluation

Ease of Use

Many of the knives I selected for this list utilize a KVT ( Kershaw Velocity Technologies ) ball bearing system that allows for the blade to open smoothly with minimal resistance. These ball bearing systems use no springs or torsion bars and instead use a group of bearings that surround a pivot point at the base of the blade. These ball bearings will rotate when combined with either the Speedsafe easy flip open or the thumb stud opening mechanism.

The thumb stud flipper is a manual opening mechanism found on a variety of the knives included in this best of the list. This easy to use system is found on near the base of the knife and can be employed by simply applying a small amount of pressure with your thumb. This opening system will force the blade open and allow the frame lock to fall into place ensuring your blade will remain open until you free the lock and close your blade.

The Speedsafe system is used in both the thumb stud and spine switch opening mechanisms. The system was designed to stay closed unless there was enough force applied to the thumb stud or the spine stud. When enough pressure is placed on either of the opening mechanisms the blade will slowly ease into the completely open position.

Responsiveness

Another aspect that these knives needed to conform to was the ability to ensure that no matter the need, the knife would open every time you pulled it out. While not its only function yet its prime function, in the event that you need this knife for self-defense the blade getting stuck when you need it most could prove to be a fatal flaw. The Zero Tolerance brand does an amazing job of not only ensuring their products will open, but they assist in the opening of the knife,  making it possible to achieve it in a swift single fluid motion.

Most knives are commonly being used to open tough plastic packaging or other equally annoying packaging products, and a dull knife is about as useful as your fingernails to open the packaging. While everyone loves the thought of a challenge you need to pick and choose your battles. In order to make your life easier, I featured blades that would retain a sharp edge and would be easy to sharpen when it becomes necessary.

Durability

No matter the purpose or intent while carrying a knife a major concern for every buyer is how well the product can withstand corrosion caused by moisture. Anyone that carries a knife regularly can tell you that somehow the knife in their pocket still ends up with the slightest bit of moisture coming in contact with it during hot days or should they be doing physical activity. The knives on this list are made with the highest quality steel composition you can find for a pocket knife. They are extremely resistant to corrosion caused by moisture and will endure the trial of time.

Even the most expensive knives in the world will someday require a sharpening. It is the inevitable price we pay for the use of high-quality steel. While it can be a challenge with many blades you won’t find that with any of the Zero Tolerance knives featured in this list.

With often use and regular opening and closing of your knife, hard particulates can and will end up with your blade and the frame when closing. These small and hard particulates can damage the finish on your knife. Many of the knives featured on this list use coated steel that will work to prevent any blemishing or tarnishing of your knife’s blade.

Having to carry a knife every day can become a bit of a task. From ensuring you have easy access and that it can be concealed in any outfit,  you already have a lot on your plate to manage. While not all of the knives on this list are as forgiving, a few of these options are nearly maintenance free. No matter your choice every blade needs to be sharpened occasionally, however, aside from that many of these options will require no additional maintenance.
