Zero Tolerance 0512BLK Spring Knife - Black
Spring-assisted knife with an overall length of 203 mm, equipped with a Clip-Point blade measuring 88 mm, crafted from CPM Cru-Wear tool steel, and hardened to a remarkable 63-64 HRC. Enhanced by a Cerakote coating, the blade delivers superior abrasion and corrosion resistance, in addition to increased impact durability. A Button Lock mechanism secures the handle, which features durable Micarta scales.
automatic opening, lock, jimping
The Button Lock system manages both the deployment and retraction of the blade. Engaging the blade is accomplished by a simple press of the button, allowing for smooth one-handed operation. This mechanism also secures the blade in the open position, providing reliable safety during use. Enhanced grip and precise control are further supported by added jimping along the spine, significantly reducing the likelihood of fingers slipping toward the blade’s edge.
ergonomic handle, spring clip
An ergonomically shaped handle constructed from two segments enhances the model’s functionality. The initial segment incorporates black Micarta composite handle scales, while the second segment is crafted from titanium finished in a black matte Cerakote coating, delivering outstanding resistance to scratches and corrosion. Secure and convenient carry is ensured through a spring deep-carry clip (tip-up, right/left side), easily attachable to a belt, the edge of a pocket, or various gear elements.

CPM CruWear
CPM CruWear is a high-performance powder steel developed by Crucible Industries. It is a tool steel that combines excellent wear resistance, high hardness, and fatigue resistance. It contains approximately 1.1% carbon, which gives it a hardness of 62-64 HRC after appropriate heat treatment, and high cutting edge retention. Thanks to its high vanadium (1.3%) and molybdenum (1%) content, CPM CruWear is characterized by high abrasion resistance, as well as increased strength and stability at high temperatures. The chromium content (7.5%) ensures very good corrosion resistance, making this steel relatively resistant to rust. CPM CruWear is commonly used in the manufacture of tools requiring exceptional wear resistance, such as tactical and premium knives, cutting tools, and dies.
Button Lock
Button Lock (also known as Plunge Lock) is a locking mechanism in folding knives based on a spring button. When fully opened, the tang enters a notch at the base of the blade and locks it in the working position; when closed, the same element acts as a detent. The design allows for smooth opening and closing with one hand and increases safety, as it does not require the user to place their fingers on the blade line. Thanks to its simplicity and reliability, the Button Lock is often used in EDC knives and collector's models.
Cerakote
Cerakote is an advanced ceramic-polymer coating applied to knife blades to increase their durability and give them a distinctive appearance. It forms a thin, opaque layer that does not alter the geometry or balance of the blade, while ensuring high durability. Its matte, non-reflective finish, available in a variety of colors, makes it a popular choice for tactical and outdoor knives. The coating is resistant to impact, chipping, and abrasion, effectively protecting the steel in demanding conditions. In corrosion tests (Salt Spray ASTM B-117), it retains its properties for thousands of hours, protecting the blade from rust and oxidation. It is also resistant to chemicals, including cleaning agents and solvents.
Micarta
Micarta is a composite material made of layers of fabric (including canvas, linen, and paper) soaked in resin and pressed under high pressure and temperature. It is characterized by high mechanical strength, resistance to impact, abrasion, and changing weather conditions, as well as dimensional stability, which makes it ideal for knife handles. The surface of Micarta provides a secure grip and can be finished smooth or left with a slight texture to improve control over the tool. The material does not conduct heat or electricity, tolerates contact with moisture well, and acquires a characteristic patina over time, emphasizing the individual style of the knife. Thanks to its combination of durability, environmental resistance, and unique appearance, Micarta is widely used in EDC, outdoor, and collector's knives.
