48,46 €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.
YAG SP Blue Micarta, Beadblasted doesn’t try to impress with its size. It’s a compact fixed-blade knife designed by Polish designer Ostap Hel as an everyday carry tool, where speed of use, simplicity of construction, and excellent control are what matter most. The manufacturer positions this model as a knife for Outdoor and Every Day Carry, and the form itself confirms this direction: a compact silhouette, minimalist handle, and lightweight construction make the knife easy to incorporate into your daily kit. The 14C28N blade features a spear point profile and a flat grind, which fits well with the character of a compact utility knife. This geometry streamlines the cutting path, provides good blade feel, and performs well for tasks performed close to the material. The matte beadblast finish enhances the technical aesthetics of the design, while the Vacuum & Cryogenic treatment supports the steel’s durability. The Micarta composite handle maintains a simple, compact form. This is a grip designed for everyday use, not flashy styling. The whole is completed by a Kydex sheath with a Tek-Lok attachment, thanks to which the YAG remains a knife ready for discreet and comfortable carrying.

14C28N - martensitic chromium stainless steel is the latest achievement in the range of knife steels produced by the Swedish steelmaker Sandvik. Its optimized chemical composition, featuring a unique combination of elements, ensures the highest quality, excellent edge performance, high hardness, and corrosion resistance. By reducing the carbon content to 0.62% (C) and increasing the chromium content to 14.0% (Cr), as well as adding 0.11% nitrogen (N), corrosion resistance has been significantly improved. Considered an improved version of 13C26 steel. Unbeatable in the price/quality category!
Vacuum & Cryogenic - 14C28N steel undergoes a specialized heat treatment process comprising two key stages. During Vacuum Heat Treatment, the steel is hardened in a vacuum environment, which minimizes oxidation and ensures more uniform metal properties. This process increases the steel’s strength and structural integrity. Cryogenic Treatment: After heating, the steel is rapidly cooled to extremely low temperatures, often below -100°C (-148°F). This transformation converts residual austenite into martensite, significantly increasing hardness, wear resistance, and overall durability. Thanks to these advanced processes, 14C28N steel delivers exceptional performance, offering both razor-sharp edge retention and remarkable blade durability.
Blade - the spear point profile gives this model a very clean, functional character. The lowered tip increases control during precision work, and the slightly curved cutting edge facilitates confident blade guidance. In a compact fixed blade, this geometry has great practical value, as it limits accidental tip penetration and facilitates work requiring precision. The cutting action is provided by a flat grind, which works well with the short blade and supports efficient material separation without excessive resistance. The beadblasted finish gives the blade a matte, technical surface.
Handle — Micarta composite grips are mounted on a full tang construction, allowing the YAG to maintain good rigidity while remaining lightweight. The grip shape is simple and practical—the knife is designed to fit comfortably in the hand and not take up too much space when carried. The manufacturer also highlights the fully ambidextrous design. The rear part of the handle is closed off by a steel loop for threading a safety lanyard. The Kydex sheath with a Tek-Lok attachment significantly enhances the functionality of this model. This solution allows the carrying style to be tailored to the user’s preferences and reinforces the EDC nature of the entire design. As a result, the YAG remains a simple, compact, and very logically constructed knife for everyday use.
