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.

CPM S35VN - American martensitic high-alloy stainless steel with a hardness of 59-61 HRC, one of the best blade steels. Designed to provide better strength compared to CPM S30V, while keeping corrosion resistance at the highest level. Manufactured by US Crucible Industries using the particle metallurgy / Crucible® Particle Metallurgy (CPM) method. The CPM process creates a very homogeneous, high-quality steel with excellent dimensional stability, grindability and ductility compared to steels produced by conventional methods. The chemical composition has been balanced so that it is composed of 0.5% niobium carbides (Nb) along with 3.0% vanadium (V) and 14.0% chromium (Cr) carbides. Replacing some of the niobium carbides with vanadium carbides makes the steel about 15-20% harder than S30V without sacrificing wear resistance, and it is also easier to machine and polish. The improved strength of CPM S35VN also provides better resistance to edge chipping.
Blade - 3.1mm thick with Leaf Shaped profile (leaf shape) provides excellent cutting edge geometry with low friction. The small thickness of the blade combined with a high, flat grind (Flat Grind) gives excellent cutting edge geometry and extreme cutting performance. Careful placement on the Blade of an enlarged 14mm circular SpyderHole cutout (Spyderco patent) positions the hand in just the right place for intuitive opening of the Blade and at the same time increases the spine jimping thumb support hump.
Handle - textured bi-directional non-slip grips (Bi-Directional Texturing) strengthen the grip. Made of FRN (Fiberglass Reinforced Nylon), a fiberglass-reinforced nylon plastic. Solid metal screw-on hourglass clip with 4-way (up/down, right/left) 4-way clip positions. In the back of the Handle a lanyard hole, a hole for pulling a safety cable.
