234,21 €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.
KB Knives Relentless Gray Titanium, Silver Bead Blasting M390 by Jake Hoback (KB462A) is a premium EDC titanium folding knife featuring a Tanto Point blade, Button Lock, and Böhler M390 steel.
KB Knives Relentless – a titanium folding knife designed by Jake Hoback
KB Knives Relentless Gray Titanium, Silver Bead Blasting M390 by Jake Hoback (KB462A) combines robust functional geometry with the clean, technical styling characteristic of Jake Hoback’s designs. The Tanto Point blade, sandblasted titanium handle, and Button Lock create a full-size folding knife designed for everyday carry and demanding utility tasks. The gray finish of the handle gives the design a subdued look, while the precise fit of the titanium components underscores the knife’s premium character.
The blade is made of Böhler M390 powder steel, which has undergone vacuum heat treatment and a cryogenic process. A hardness of 60–62 HRC promotes long-lasting sharpness, and the flat grind ensures effective cutting through cardboard, cord, plastic, and other utility materials. Ceramic ball bearings support smooth opening via the flipper, and the reversible titanium clip allows the knife to be carried on the right or left side in a tip-up configuration.
Böhler M390 steel Tanto Point blade
The Tanto Point profile features a strong tip and a distinct edge break, which supports precise scoring and controlled operation of the blade tip. The flat grind reduces resistance during cutting and preserves the appropriate amount of material behind the edge, making the blade well-suited for everyday and tactical-utility tasks. The Silver Bead Blasting finish gives the surface a uniform, matte texture and reduces intense light reflections.
Böhler M390 offers very good wear resistance, high corrosion resistance, and long-lasting sharpness. Vacuum treatment combined with cryogenic freezing helps achieve uniform steel properties at a hardness of 60–62 HRC. The material is well-suited to a full-size premium folder, where edge stability and reduced sharpening frequency are key.
Titanium Handle and Button Lock
The handle, made of Titanium, ensures high rigidity, mechanical resistance, and a favorable strength-to-weight ratio. The Gray Sandblasted finish gives the surface a subdued, industrial character and complements the silver blade well. The titanium backspacer reinforces the rear of the construction and maintains the knife’s material consistency.
The Button Lock allows you to conveniently release the blade with a button, without placing your fingers in the path of its movement. Ceramic ball bearings ensure smooth pivot operation, while the flipper allows for quick, one-handed manual opening. The titanium right/left tip-up clip lets you adjust the carrying side, and the included Pouch protects the knife during transport and storage.
