193,06 €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.
Microtech Utility Caribbean Blue G10, Stonewashed M390MK (3400-10CA) – a kitchen utility knife made of Böhler M390MK steel
The Microtech Utility Caribbean Blue G10, Stonewashed M390MK (3400-10CA) is a utility kitchen knife designed for users who expect a precise tool for portioning, slicing, and everyday work at the cutting board. The blade, made of Böhler M390MK steel with a utility profile, a flat grind, and a Stonewashed finish, is engineered for long-lasting sharpness, corrosion resistance, and controlled blade guidance. The G10 handle ensures a stable grip in the kitchen environment, even with wet hands. The included blade guard facilitates safe storage and transport of the knife outside the kitchen block.
Böhler M390MK – powder steel developed for Microtech
Böhler M390MK is a high-performance powder steel associated with the Microtech line, designed for excellent wear and corrosion resistance and long-lasting edge retention. In the Utility kitchen knife, it ensures effective performance when slicing vegetables, portioning ingredients, working with meat and herbs, and in everyday food preparation. The lack of confirmed hardness data for this specific model means that the table shows “N/A,” without including values from the steel’s general specifications.
Utility profile and flat grind – precision in the kitchen
The utility profile works well for tasks that fall between those of a small utility knife and a larger chef’s knife, providing good control when slicing, portioning, and chopping. The flat grind supports a smooth cutting line, reduces resistance in the food, and helps guide the blade evenly through vegetables, fruits, meat, and ingredients with varied textures. The Stonewashed finish gives the blade a matte, utilitarian look and better conceals minor marks that arise during regular use.
G10 and fixed-blade kitchen knife construction – stability and hygiene
The handle made of G10 combines resistance to moisture, temperature, and typical mechanical stress with secure hand support. The milled surface improves grip, while Torx screw fastening increases the structure’s rigidity and facilitates access to assembly components during maintenance. The absence of a classic sheath is compensated for by a blade guard, which protects the edge and the user during storage.

Frequently Asked Questions
How do I care for and sharpen the Böhler M390MK steel in the Microtech Utility knife?
Böhler M390MK steel should be cleaned, dried, and stored away from humid environments after use, especially after contact with acidic foods. For sharpening, a diamond sharpener or a high-quality ceramic system works best, as powder steel with high wear resistance requires an effective abrasive and a stable angle.
What tasks is a utility kitchen knife best suited for?
A utility knife is best suited for slicing vegetables, fruits, sandwiches, smaller portions of meat, herbs, and products that require more control than a large chef’s knife. Its versatile design allows for comfortable use in both quick kitchen tasks and more precise portioning.
Is a G10 handle suitable for kitchen use?
Yes, G10 works well in the kitchen because it is resistant to moisture, temperature, and typical mechanical stress. The textured surface improves grip, and the rigid handle construction supports control over the blade during prolonged use.
Does the knife come with a sheath?
No, this model does not come with a traditional sheath or holster. However, the set includes a blade guard that protects the cutting edge and makes it easier to store the knife safely in a drawer, bag, or kitchen organizer.
What makes the Stonewashed finish on a kitchen knife stand out?
Stonewashed gives the blade a matte, industrial look and helps mask minor scratches that occur during regular use. In the kitchen, this is a practical finish because the knife retains its rugged character despite contact with cutting boards, food, and daily washing.
