24,94 €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 Microsub PT Black ABS, Mirror Stainless Steel W 1.4116 – a compact diving knife with a blunt tip
Mac Coltellerie Microsub PT Black ABS, Mirror Stainless Steel W 1.4116 (MRS06PT.N) is a compact diving knife with a fixed blade, designed as a handy emergency tool and backup model. It combines a Blunt Tip, a smooth and serrated edge, and a lightweight ABS handle that makes it easy to control the knife underwater and while wearing gloves.
The polymer sheath is equipped with two rubber straps with buckles, allowing it to be attached to the hand, calf, or other pieces of equipment. A hole in the Handle allows for the use of a safety lanyard, while a slot in the blade can be used to open and close carabiners.
Stainless Steel W 1.4116 – steel for marine applications
The blade is made of W 1.4116 stainless steel with a hardness of 55–56 HRC. This material provides good corrosion resistance, is easy to maintain, and can be sharpened effectively. After contact with saltwater, the knife should be rinsed with fresh water and thoroughly dried.
Dagger, Blunt Tip, Flat, and Mirror
The Dagger, Blunt Tip profile features a flattened tip that reduces the risk of accidentally piercing a wetsuit, jacket, line, or piece of equipment. The Flat grind facilitates smooth cutting, and the polished Mirror finish gives the blade a smooth, bright surface.
Smooth and serrated edge and ABS handle
One side of the blade has a smooth edge for more precise cuts, while the other is serrated and makes it easier to cut through ropes, straps, nets, and fibrous materials. The contoured black ABS handle provides a secure grip, and its compact size makes the Microsub PT a great backup knife.

Frequently Asked Questions
How do I care for 1.4116 steel after diving in saltwater?
After each dive, the knife, sheath, and straps should be thoroughly rinsed with fresh water. Then, all components must be dried, paying special attention to the serrated edge and the points where the blade meets the sheath.
What is the Blunt Tip used for?
The Blunt Tip reduces the risk of accidentally piercing a diving suit, hoses, a BCD, or other pieces of equipment. It can also help when prying and separating materials.
What is the hole in the blade used for?
The hole serves as a socket for carabiners. It allows you to unscrew or tighten specific carabiners used in diving and sailing equipment.
When should you use the serrated edge?
The serrated edge makes it easier to cut through ropes, nets, straps, belts, and other fibrous materials. The smooth edge is better suited for more controlled and precise cuts.
How do you attach the Microsub PT knife sheath?
Two rubber straps with buckles allow you to attach the sheath to your hand, calf, or a piece of gear of your choice. Adjust the straps so that the sheath remains secure but does not restrict circulation.
