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.
Infraction Blue/Silver Titanium "Peaks and Valleys", Std HW, Brsh Clip, Tumbled, proposal for those who find a full-size folding knife a bit bulky. MKT has embarked on a mission to create a true marvel - a folding knife with handmade customizations, featuring slimmer lines than the Praetorian series, yet still built like a tank. A "Made in USA" workhorse knife designed for the toughest cutting tasks is one of the smallest and lightest knives with ever produced.
Each Medford is handmade by talented knife makers. Therefore, there may be individual differences that make each knife unique. Production of most knives takes about a year after the order is placed. Like other knives from Medford Knife & Tool, the Infraction features a hand-crafted hollow grind. This is a unique feature: only a few manufacturers are capable of making a hollow grind by hand.
Greg Medford's idea was to create the most reliable knives imaginable while retaining their beauty and adding the "soul" of hand finishing.
CPM S45VN - American martensitic high-alloy stainless steel with a hardness of 59-61 HRC, one of the best steels for blades. Designed to provide better strength compared to CPM S30V, while keeping corrosion resistance at the highest level. Manufactured by US Crucible Industries using the particle metallurgy / Crucible® Particle Metallurgy (CPM) method. The CPM process creates a very homogeneous, high-quality steel with excellent dimensional stability, grindability and ductility compared to steels produced by conventional methods. The chemical composition has been balanced so that it is composed of 0.5% niobium carbides (Nb) along with 3.0% vanadium (V) and 14.0% chromium (Cr) carbides. The improved strength of CPM S45VN also provides better resistance to edge chipping.
Blade - slim Drop Point profile finished with a machine-applied "tumbled" technique. The hand-crafted medium-height hollow grind delivers exceptional piercing and slicing capabilities with tank-like durability. The striking combination of the finger groove and thumb hole and the minimalist front flipper make the blade truly unique. To enhance resistance to debris, phosphor bronze washers are used, making the pivot mechanism more reliable for field use. A powerful titanium frame lock bar secures the blade from folding, unfolded and secured the knife is as solid as an armoured cash register.
Handle - crafted from two solid blocks of titanium, each 28.5 mm thick. The scales have been custom hand-covered with a 3D sculpting named "Peaks and Valleys" by the manufacturer. The entire piece is hand-colored using a torch, creating a unique pattern that guarantees the distinctiveness of this knife—each subsequent knife will feature a different design due to the nature of hand customization. The stepped texture of the scales and finger grooves ensure an excellent grip during use. The titanium backspacer culminates in a glass breaker with a hole for attaching a lanyard, whether for security or decoration. Completing the design is a robust titanium clip, perfectly complementing the handle's durability and aesthetic.
The knife is supplied in a waterproof and dustproof - IP67 and shockproof (MIL-STD-810F) technical case from the American S3 Case Company, made of high-impact S433 resin - one of the most durable materials available in the world.
Included - cardboard packaging, S3 Case technical case, Dog Tag immortal and signed "Certificate of Creation and Authenticity".
