0,00 €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.
Kubey Ishtar Gray Titanium Folding Knife, Sandblasted M390 by Maksim Tkachuk (KB170A)
The Kubey Ishtar KB170A is a titanium folding knife designed by Maksim Tkachuk, combining a Böhler M390 steel blade with a gray, sandblasted handle. Its slim silhouette, Straight Back profile, and a mechanism based on a Frame Lock and ceramic ball bearings create a modern design with a distinctly utilitarian character.
The 90.00 mm blade features a flat grind and a sandblasted finish. The knife is opened manually via a thumbhole in the blade, and once deployed, the blade is secured by the Frame Lock.
Böhler M390 – Steel with High Wear Resistance
The blade is made of Böhler M390 steel, hardened to 60–62 HRC. The material is characterized by high resistance to abrasion and corrosion, as well as very good edge retention, which makes it well-suited for a folding knife intended for regular use.
Straight Back, flat grind, and sandblasted finish
The Straight Back profile provides a long, functional cutting edge and a well-controlled tip. The flat grind ensures smooth cutting through materials, while the sandblasted finish gives the blade a matte, technical look.
Gray Titanium, Frame Lock, and Ceramic Bearings
The handle is made of titanium and finished in a gray, sandblasted variant. The backspacer and clip are made of the same material, creating a visually cohesive design. Ceramic ball bearings ensure smooth blade movement, and the Frame Lock uses a titanium body as the locking element.

Frequently Asked Questions
How do I care for Böhler M390 steel?
It’s a good idea to clean and dry the blade regularly. M390 is highly corrosion-resistant, but proper care helps preserve both the cutting edge and the surface’s appearance.
How do I sharpen the Kubey Ishtar?
It’s best to maintain the factory edge geometry and apply the abrasive evenly along the entire length of the blade. High-performance diamond sharpening systems work well with M390.
How does the Frame Lock work?
The Frame Lock uses a section of the titanium handle as a locking element to secure the blade once it is open. Releasing the lock allows the knife to be folded.
How do you clean a sandblasted titanium handle?
For daily cleaning, it’s best to use a soft, slightly damp cloth. Avoid harsh abrasives, which can alter the appearance of the matte finish.
How do you care for ceramic ball bearings?
Keep the area around the pivot clean and protected from excessive dust and dirt. If necessary, you can use a small amount of a cleaner designed for knife mechanisms.
