The Kershaw Leek 1660CF is a popular everyday knife that uses the American 154CM stainless steel blade, which features an easy-open blade and ultra-lightweight carbon fiber sheath.Composite steelThe Kershaw Leek 1660CF model is designed for everyday use, clearly emphasised by its small size, lightweight construction and typically functional style .The knife is 76mm long with a blade made from tool steel hardened to 154CM hardness and tempered to 58-60 HRC hardness, which is optimal for EDC knives. The 154CM is a stainless steel with a molybdenum alloy with a very high carbon content, which can be described as an improved version of the 440C material.The American steel is particularly appreciated for its resistance to corrosion and abrasion (high toughness), long life and relatively easy sharpening.The thin blade with an aggressive wharncliffe profile has a uniform matt polished surface. Thanks to the narrow tip, concave cutting and almost straight cutting edge, the knife has excellent cutting properties and the blade does not stick to the material.The blade thickness at its widest point is 3 mm, which is a compromise between durability and functionality of the knife in everyday work.Convenient to useThe blade can be opened with one hand in two ways : with a mart flipper or with a double-sided pin, allowing you to choose the method according to your preferences.Both solutions are convenient for both right and left-handed users, allowing you to carry the knife safely and comfortably in your pocket. The opening process is facilitated by the SpeedSafe opening mechanism.When you press the flipper, the opening mechanism activates an internal spring that dynamically opens the blade and the knife is ready for use in a split second.Two locksA monolithic locking frame, considered one of the most durable locking mechanisms, protects the blade from accidental opening. The main lock is supported by an additional Tip safety lock .A sliding latch on the top of the knife prevents accidental opening of the blade when folded .Interchangeable tweezersCarrying the knife in a discreet pocket allows the use of a high fixed clip to mount the tweezers on either side. Next to the tweezers there is a hole for attaching a decorative paracord braid, which is very popular with knife owners.Stylish and elegant handleThe knife handle is made of light and very durable carbon fibre sheathing attached to steel liners, which are responsible for the rigidity and strength of the structure. One of the main advantages of carbon fibre, apart from its obvious striking appearance, is its minimal weight, which affects the overall weight of the knife.The profiled and slender shape of the handle makes the knife very firm and comfortable in the hand, regardless of its size.TECHNICAL SPECIFICATIONSPage informationBlade profile WarncliffSteel hardness [HRC] 58-60Blade lock type Keretz lockKnife type foldingKnife typeFlipper machine,thumb studSteel type stainless steel - 154 cm Additional informationClip for carrying is availableBlade material carbon fibreCorrosion resistance highDull resistance okCut type concave Opening support yes, spring-loadedDimensionsTotal length [mm] 179Blade length [mm] 76Length after folding [mm] 102Blade thickness [mm] 3Weight [g] 69Manufacturer's dataManufacturer Kershaw, USA
