71,13 €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.
MAC Coltellerie Gunslinger Scuba Black FRN, Satin 420 by Riccardo Silva – a diving knife with a Dagger / Harpoon blade
The MAC Coltellerie Gunslinger Scuba Black FRN, Satin 420 by Riccardo Silva (MC GLRSA.N) is a compact diving knife with a fixed blade, designed for emergency and rescue applications. The model combines a Dagger/Harpoon profile, a smooth and serrated edge, a distinctive pistol-shaped FRN handle, and a black polymer sheath with mounting straps.
The contoured handle allows for multiple grip styles and provides firm support for the hand when working with wet gloves. A steel glass breaker is located at the end of the handle, expanding the knife’s functionality in rescue applications.
420 Stainless Steel – Practical Maintenance in Aquatic Environments
The blade is made of 420 stainless steel. This material offers good corrosion resistance and can be resharpened relatively easily. After contact with saltwater, the knife should be thoroughly rinsed with fresh water, dried, and periodically treated with an appropriate preservative.
Dagger / Harpoon, Flat, and Satin
The Dagger / Harpoon profile is distinguished by a pronounced tip and a technically shaped spine. The Flat grind supports effective cutting, while the Satin finish emphasizes the blade’s functional character. The combination of a smooth and serrated edge allows you to adapt your cutting technique to the material being cut.
Pistol-grip FRN handle and sheath with straps
The handle is made of FRN – Fiberglass Reinforced Nylon. Its pistol-grip shape provides firm support for the hand and allows for a comfortable change of grip. The black polymer sheath can be secured to the arm, leg, or a compatible piece of gear using two rubber straps with plastic buckles.

Frequently Asked Questions
How do I care for 420 steel after contact with saltwater?
