Buyers Guide

Is this your first time buying a Zero Tolerance knife? If so, you probably have a few questions on what to look out for. Don’t sweat! We have you covered with our buyers guide below which contains everything that you need to know about these particular knives.

Blade Type

Zero Tolerance knives have a reputation when it comes to drop point blade quality. Designed for continual use they are coated often using an anodizing process. The anodizing coating gives extra durability to the knives and blade steel ensuring that it can be used in all types of survival scenarios. This electrolytic process manipulates the oxide layer of the blade which creates a colored surface.

In addition to this, the knife blade is sprayed with a special layer of glass and aluminum oxide beads. This process takes place under high speeds and pressure to smooth out the blade surface and affects whether the blade is lighter or darker in color.

ZT also has a blackwash blade range which produces the impression of a well-used knife. This finish on the knife helps to prevent scratches from occuring on the blade and adds further blade protection too. There is also a Tungsten DLC coating that uses properties similar to that of a diamond on the blade. While this coating certainly adds to the overall aesthetic, it is not used for solely this purpose. Instead, it adds high wear, hardness, and extra resistance to the blade.

There is also a range of other blade finished including a PVD coating, Satin finish, Stonewashed finish, Two-tone finish, and Working finish.

Handle Material

Zero Tolerance knives are all designed to be extremely durable and stable at the same time. They are also designed to be extremely lightweight in order to be carried around with ease. Different models also include 3D handles which provide better grip and comfortable contouring to improve grip.

Carbon fiber – In carbon fiber handle knives ZT, the material produces an extremely lightweight feel. Carbon fiber atoms are bonded alongside crystals in long strands that are then woven together into fibers.

Titanium – A titanium handle is lightweight and corrosion-resistant but they also provide a high amount of strength. ZT knives use a titanium handle, liners, lock bars, and as part of their certain coatings too.

G10 – This epoxy filled glass filler is stable and unaffected by temperature changes. The material makes excellent handles for knives and offers comfort at the same time.

Opening System

Most ZT knives offer users a fast and easy way opening mechanism that only requires a single hand. Most models come with either a KVT ball bearing system or a SpeedSafe opening that is assisted. However, some of these knives do come with other opening systems and different ways to access them.

For those that prefer to open their knives using their index finger, a flipper action system is for you. The flipper is essentially an extension found towards the back of the pivot and it can be found on both manual and assisted folders. To open the framelock flipper using a single hand you simply hold the knife vertically in one hand and place the index finger onto the flipper tab. Then you just apply gentle pressure onto the flipper and the SpeedSafe mechanism opens the knife quickly and easily.

The different opening actions found across ZT models vary. These pocketknives provide a smooth way of opening and provide knife safety at the same time. A manual opening with a KT ballbearing relies on the ring of caged balls that surrounds the pivot. This mechanism makes opening the knives as easy and as smooth as possible.

ZT also sell knives with manual washer openings, they function without springs or ballbearings and instead rely on washers as well as a pivot. They can be opened with a thumb stud, nail nick, or flipper.

One of the most popular types of opening mechanisms found on a ZT knife is the SpeedSafe assisted opening. As the name probably suggests, it ensures a speedy yet safe opening for the user. It functions using a manual thumb stud or flipper and when closed the torison bar creates a bias.

Lock Type

Locking mechanisms on a folding knife must operate in a sense that they keep the locked until the user chooses to open the blade. Most ZT most knives utilize a detent towards the bias which enables safe closing when carrying. If the knife that you choose features a frame lock, this means that its ‘frame’ uses two plates of material positioned on each side of the knife’s blade.

When the carry knife opens with a frame lock, the lockbar moves up towards the back part of the blade and prevents it from closing. If you want to unlock a titanium framelock, you should hold the knife using a single hand and turn the knife so that the interior of the handle is facing you. Next, on the left side of the handle you can locate the lock and using your thumb you should press it down. With the other hand now, hold the back of the blade and begin to guide it back into the titanium handles.

Blade Edge

ZT knives come with two types of edge including plain and partially serrated. The plain edge of a blade is sometimes best known as ‘straight’ or ‘fine’ Most ZT knives have a plain edge though some do offer serrated blades too.

Plain edge – A plain blade edge is a style that almost all are familiar with. The blade’s steel is ground down and sharpened to a fine point along the edge. The sharpened edge will be visually a bit lighter than the rest of the blade, and it carries multiple benefits. The general-purpose cutting edge offers multi purposes, is great at a push and slice edc cuts, and is super easy to look after.

Partially serrated edge – The partially serrated edge on a ZT knife is particularly useful for cutting up materials such as rope and in some cases wood. Sharpened on a single side, like that of the plain blade, the serrated edge is even sharper and has serrations on it which help to cut through the toughest materials. The benefits of using this type of edc knife include extra versatility, easy cutting, and sharp serrations.
