15,71 €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 A450 Black PP, Mirror 420 – mushroom knife with a Hawkbill blade and a cleaning brush
The MAC Coltellerie A450 Black PP, Mirror 420 mushroom knife (MC A450.N) is a lightweight folding knife designed for picking and pre-cleaning mushrooms. The model combines a curved Hawkbill blade, a traditional Slip Joint mechanism, a black PP handle, and an integrated brush for removing dirt, sand, and pine needles.
The blade opens with both hands using the Nail Nick. A carabiner loop allows you to attach the knife to a basket, backpack, bag, or belt loop, keeping it easily accessible while picking mushrooms.
AISI 420 – easy-to-maintain stainless steel
The blade is made of AISI 420 stainless steel with a hardness of 52–54 HRC. This material provides good corrosion resistance and allows the blade to be easily resharpened. After use, clean the blade of any plant debris, rinse it, dry it thoroughly, and store it in a dry place.
Hawkbill, Full Flat, and Mirror
The Hawkbill profile features a curved, hollow edge that helps grip the stem of the mushroom and prevents the blade from slipping while cutting. The Full Flat grind promotes efficient cutting, while the Mirror finish gives the blade a smooth, polished surface.
Black PP, cleaning brush, and Slip Joint
The handle is made of black polypropylene PP. The textured surface provides a secure grip when working in damp conditions. A brush is located at the rear, allowing you to clean the cap and stem before placing the mushroom in the basket.

Frequently Asked Questions
How do I care for AISI 420 steel after mushroom picking?
After use, clean the blade of dirt, plant debris, and moisture. Then rinse it, dry it thoroughly, and periodically apply a thin layer of a suitable preservative.
How does the Slip Joint mechanism work?
The Slip Joint uses a spring that holds the blade in both the open and closed positions. The mechanism does not lock the blade rigidly in place, so you should avoid applying pressure to the spine of the blade while working.
What is the brush in the Handle used for?
The brush allows you to remove dirt, sand, pine needles, and small debris from the cap and stem of the mushroom. It lets you pre-clean your harvest while still in the forest.
How do you sharpen the curved blade of a Hawkbill?
For sharpening, it’s best to use a narrow ceramic rod, a conical sharpening stone, or a system designed for a hollow edge. Guide the blade evenly, maintaining the original angle along the entire length of the curve.
How do I clean the PP handle?
The handle can be washed with water, a mild detergent, and a soft brush. Pay special attention to the brush, the area around the pivot, and places where dirt and plant debris may accumulate.
