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.

In 1990, Spyderco launched two models of knives: the Endura and Delica, creating demand for lightweight one-handed opening folders at an affordable price. These products have become bestsellers. Thanks to their small size and low weight, they are an excellent choice as everyday EDC knives .
CPM SPY27 - a proprietary blend of alloys, including vanadium, molybdenum, niobium, nitrogen and cobalt. The high-alloy stainless steel contains 1.4% carbon and a 1% admixture of niobium (Nb), one of the best carbides, which contributes to the steel's wear resistance. Thanks to its properties, the steel holds sharpness for a very long time and guarantees aggressive cuts for a long time. It is easy to sharpen, corrosion resistant and contains a high admixture of 14% chromium. It provides good strength and cutting edge retention, as well as a fine-grained structure. Produced 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 toughness compared to steels produced by conventional methods.
Blade - with Clip Point profile , 2.5 mm thick , coated with black non-reflective titanium carbide (TiCN) coating. Plain blade was derived with Full Flat Grind for excellent geometry and strength. On the back of the Blade , a notched ramp (jimping / crosshatching) positions the thumb, gives solid support and makes it easier to operate the folder. The 13mm round SpyderHole cutout (Spyderco patent) allows you to open the knife with one hand using your thumb. Blade lock of Back-Lock type with additional Boye Detent cutout , preventing accidental release of the lock when gripping the knife firmly.
Handle - in elite color Cobalt Blue. Non-slipbi-directional textured covers (Bi-Directional Texturing) and notched notches on the back of the Handle (Spine Jimping) strengthen the grip even with wet hands. Made of FRN (Fiberglass Reinforced Nylon), a fiberglass-reinforced nylon plastic. Metal hourglass clip with 4-way (up/down, right/left) 4-way clip positions. In the rear part of the Handle a hole (lanyard hole ) for a cord.
Skeleton - steel plates with cut-out holes, to which the grips are attached. This provides high strength and stiffness with low weight of the knife. Reinforced fully demountable construction connected by torx screws. Phosphor bronze washers for easy opening and closing.
