185,41 €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.

This excellent tool has gained a new dimension, becoming an excellent working knife that is up to any task! And all this while maintaining excellent value for money!
CPM M4 - commonly referred to as M4, is a high-speed tool steel with balanced properties manufactured at American Crucible® Industries steel mills. It is produced by particle metallurgy / Crucible® Particle Metallurgy (CPM). The CPM process produces a very homogeneous, high quality steel with excellent dimensional stability, grindability and ductility compared to steels produced by conventional methods. It contains large amounts of vanadium 4.0% (V) and tungsten 5.5% (W) in its composition, which increases its strength and wear resistance. This gives it better performance than the M2, M3 and M7 varieties. The improved strength and wear resistance make this steel an excellent choice for premium and custom knives. Hardened in the 58-65 HRc range, CPM M4 is used for knives, cold working tools, punches and dies.
Combination Edge - (partially serrated), a combination of a serrated Spyder blade for aggressive cutting of hard materials, plastics, fibers, and a classic Plain blade used for precision cuts. The Spyder blade consists of alternating one large and two small teeth, the so-called two-step. This pattern increases the length of the cutting edge by up to 24% compared to a straight blade.
Blade - with the company's Leaf-Shaped profile (leaf shape), finished in an elegant Satin method. Combination blade (partially serrated) was derived with Full Flat Grind. The enlarged 14mm round SpyderHole cutout (Spyderco patent) makes it easy to open the folder with cold or wet hands. The notched section of the Blade's back, ramp (spine jimping) gives solid support for the thumb which makes it easier to operate the knife. The entire blade is locked with the proven Liner Lock.
Skeleton - made of stainless steel plates, for the relief of openwork, which provide exceptional strength of construction, while forming the basis of Michael Walker's Liner Lock blade locking mechanism with notched liner. The whole was bolted together with torx screws for easy unfolding and folding of the folder.
Handle - made of G10 composite (pressure-pressed fiberglass with synthetic resin), beveled edges of the covers eliminate sharp edges. Open-backed design - so called open-backed design fixed with steel spacer sleeves reduces weight and facilitates cleaning. Metal clip with four-way (up/down, right/left) 4-way clip positions. A hole (lanyard hole) in the back of the Handle for attaching a safety line.
