- StaySharp™ Technology - Ultimate edge durability!!! The tungsten carbide blade will stay sharp longer than any other knife due to the unique properties of the blade material with an incredible hardness of 71HRC!

This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
Sharper, thinner and harder than any blade ever made, the TCK 2.0 is an ultra-thin "gentleman's folder" suitable for everyday carry. Featuring a blade of patented Polyhedral Tungsten Carbide with a Rockwell hardness of 71 HRC, the TCK 2.0 far surpasses any production knife with a steel blade. Scientifically proven to maintain a sharp edge longer than any other knife, the TCK 2.0 may be the last EDC you will ever need. It was designed to cut, cut and cut some more.
This sleek slip joint design knife features a patented tungsten carbide blade. StaySharp Technology™ keeps a clean, sharp cutting edge longer than any of the traditional steel blade folding knives in production. This state-of-the-art cutting tool is nestled between precision-machined stainless steel handles, accented by beveled edges and finished with a durable black coating. Red accents add the final touch that sets you apart from the crowd. Sleek and elegant, the TCK 2.0 is invisible in your pocket until you need it.
The pivot is supported by phosphor bronze washers, the mirror-polished 71 HRC hardness blade intrigues the eye with a series of mathematically designed circles, cut to reflect the Fibonacci sequence of numbers. The unique TCK 2.0 blade, with a DLC mirror finish, sparkles like obsidian at night.
The single position steel clip can be removed if you don't want to spoil the clean line of the knife with any protrusions.
Sandrin Knives is part of Turmond S.P.A., a company that has been manufacturing high-end knives and industrial components made from tungsten carbide since 1969. Years of experience have led to the development of the StaySharp Technology™ to produce a 71HRC blade hardness which translates into unbelievably long blade life. This hardness was previously achieved by knives made of ceramic, but unlike ceramic, the StaySharp Technology™ blade remains flexible. These properties make this material ideal for the blades of traditional folding knives.
