Reinforced fully dismountable construction combined with torx screws facilitates cleaning, adjustment of the folder. Thanks to improved ergonomics and design, the knife gained rigidity, functionality and aesthetics.
In 1990, Spyderco introduced two models of knives: Endura and Delica, creating the demand for light folders that open with one hand at an affordable price. These products have become bestsellers. Due to their small dimensions and low weight, they are an excellent offer as EDC daily use knives.
Blade - with a Clip Point profile, 3 mm thickness, made of Japanese VG-10 stainless steel (easy to sharpen, resistant to corrosion) covered with a mate, non-reflective TICN (Non-Reflective Titanium Carbonitride) coating. The blade is hardened in the range of 59-61 HRC. The serrated blade of the Combination type has been made with a cut Flat Saber Grind. On the ridge's back, the ribbed ramp under the thumb. SpyderHole (Spyderco patent) allows you to open the knife with your thumb. Blade lock (Back-Lock) with additional protection against accidental release of the lock during a strong grip (notch in the blockade) of David Boye's project.
Handle - in orange color covered with non-slip textured Bi-Directional Texturing reinforces the grip even with wet hands. Made of plastic FRN (Fiberglass Reinforced Nylon), fiberglass reinforced nylon. The folder is equipped with a solid metal screw-on clip with the possibility of fixing in four planes (up / down, right / left). 4-way clip positions. Notching the notch on the Spine Jimping handle increases comfort and grip.
Frame - folder reinforced with two steel plates with holes cut into which cladding was attached. This ensures high durability with a low knife weight. The whole was screwed by torx screws. The phosphor bronze pads make it easier to open and close the penknife.
Combination Edge - (partly serrated) often used in tactical, rescue and survival knives. This unique Spyderco blade consists alternately of one large and two small teeth called „two-step”. This pattern increases the cutting edge length by up to 24% compared to the straight edge. Ideal for cutting hard materials, plastics and fibrous materials.

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.
