Why Choose the Kershaw Blur 1670BLKST? Unpacking Its Core Strengths

The Kershaw Blur 1670BLKST is engineered to solve common challenges faced by knife users: finding a balance between robust construction and comfortable portability, ensuring quick access when every second counts, and maintaining a sharp edge through consistent use. This model excels by integrating several key features that address these needs directly.

The Blade: Precision, Power, and Prowess

At the heart of the Kershaw Blur 1670BLKST lies its exceptional 3.40-inch blade, a true marvel of metallurgy and design.

• Superior Steel Choice: Sandvik 14C28N
  • What is Sandvik 14C28N Steel? This is a chromium-alloyed steel optimized for high-quality knife blades, developed in partnership between Kershaw and Sandvik Steel. It's known for its excellent balance of properties, including very good edge performance, high hardness (allowing for a keen edge), exceptional corrosion resistance, and relative ease of resharpening. Unlike some super steels that are notoriously difficult to sharpen in the field, 14C28N allows users to maintain a razor-sharp edge with standard sharpening tools, making it highly practical for everyday use.
  • Benefits:
    • Outstanding Edge Retention: Holds a sharp edge through demanding cutting tasks, reducing the frequency of sharpening.
    • High Hardness: Enables the blade to take and maintain a very fine, keen edge, crucial for precise cuts.
    • Excellent Corrosion Resistance: Ideal for use in various environments, including humid or wet conditions, without fear of rust or degradation. This makes it suitable for outdoor activities, marine environments, or even just daily carry where exposure to moisture is common.
    • User-Friendly Sharpening: While durable, it remains relatively easy to sharpen, ensuring your knife is always ready for action.
• Distinctive Blade Profile: Drop Point with Recurve
  • Drop Point Design: The drop point is a highly versatile and popular blade shape. It features a convex curve from the spine to the tip, creating a strong, thick tip ideal for piercing tasks while retaining plenty of belly for slicing. This combination makes it excellent for general utility, hunting, and even tactical applications.
  • Recurve Enhancement: The recurve is a subtle S-curve along the cutting edge. This design element significantly increases the effective cutting surface, allowing for more aggressive slicing, especially through fibrous materials or when drawing the blade across a surface. It excels at cutting rope, webbing, cardboard, and other tough materials that might slip on a straight edge.
• Partially Serrated Edge (Part Serrated)
  • Versatility Defined: The partial serration combines the best of both worlds: a plain edge for clean, precise slicing and a serrated edge for sawing through tough materials.
  • Practical Applications: The plain edge is perfect for push cuts, fine detail work, and general utility where a clean cut is desired. The serrated section excels at tasks like cutting through rope, seatbelts, zip ties, or coarse fabrics, where a sawing action is more effective. This makes the 1670BLKST an incredibly versatile tool, ready for almost any cutting challenge you might encounter.
• The Striking DLC Blackwash Finish
  • Diamond-Like Carbon (DLC) Coating: DLC is an incredibly hard, thin, and durable coating that offers exceptional wear resistance and a low friction coefficient. It's applied using a vacuum deposition process, bonding tightly to the steel.
  • Blackwash Aesthetic: The Blackwash finish is Kershaw's unique stonewash-like treatment over the DLC coating. This not only gives the blade a rugged, broken-in look but also helps to hide scratches and wear marks that would be much more apparent on a plain or uniformly coated blade.
  • Functional Benefits:
    • Enhanced Durability: Protects the blade from scratches, abrasions, and general wear and tear, extending its lifespan.
    • Reduced Friction: Allows the blade to glide more easily through materials, improving cutting efficiency.
    • Corrosion Protection: Adds an extra layer of defense against rust and environmental damage.
    • Non-Reflective: The matte, dark finish minimizes glare, a crucial feature for tactical or outdoor use where stealth is desired.

The Handle: Unyielding Grip, Lightweight Durability

The handle of the Kershaw Blur 1670BLKST is just as meticulously designed as its blade, focusing on secure handling and robust construction.

• Material Excellence: Black Anodized 6061-T6 Aircraft-Grade Aluminum
  • Why Aluminum? 6061-T6 aluminum is a high-strength aluminum alloy widely used in aerospace and automotive industries due to its excellent strength-to-weight ratio. It provides incredible rigidity and durability without adding excessive bulk.
  • Anodization: The black anodized finish isn't just for aesthetics; it electrochemically bonds a hard, protective oxide layer to the aluminum surface. This layer significantly enhances corrosion resistance and scratch resistance, making the handle exceptionally durable and resistant to fading or chipping.
• Revolutionary Trac-Tec Inserts
  • What are Trac-Tec Inserts? These are textured, rubberized inserts strategically placed into the aluminum handle scales. They are a proprietary feature of Kershaw knives, designed to provide superior grip.
  • The Science of Grip: The Trac-Tec material offers a high coefficient of friction, ensuring your hand stays firmly connected to the knife, even when wet, cold, muddy, or gloved. This is a critical safety feature, especially in high-stress or emergency situations where a slip could be dangerous.
  • User Confidence: Whether you're working in the rain, with slippery hands, or in challenging environments, the Trac-Tec inserts instill confidence, allowing you to focus on the task at hand rather than worrying about your grip.
• Ergonomics and Comfort: The handle's contoured shape is designed to fit comfortably and securely in a wide range of hand sizes, minimizing fatigue during prolonged use and providing excellent control for precise operations.

Deployment and Locking Mechanism: Speed, Safety, and Reliability

The true hallmark of the Kershaw Blur series is its rapid and secure deployment system.

• Kershaw's SpeedSafe® Assisted Opening System
  • How it Works: SpeedSafe is a torsion bar system that assists in opening the blade. By applying pressure to the ambidextrous thumb studs, the user overcomes a detent, and the torsion bar takes over, rapidly propelling the blade into the open and locked position.
  • One-Handed Operation: This system makes the Blur incredibly fast and easy to open with just one hand, whether you're right-handed or left-handed. This is invaluable in situations where your other hand is occupied, or quick access is paramount.
  • Not an Automatic Knife: It's important to note that SpeedSafe is an assisted opening mechanism, not an automatic (switchblade) knife. The user must initiate the opening process by pushing the thumb stud.
• Dual Thumb Studs: Positioned conveniently on both sides of the blade, the thumb studs provide symmetrical access for quick and intuitive opening by either hand.
• Secure Liner Lock:
  • What is a Liner Lock? The liner lock is a widely trusted and robust locking mechanism. A portion of the knife's internal liner springs into place behind the blade's tang when the blade is fully open, securely locking it into position.
  • Safety First: This mechanism prevents accidental blade closure during use, offering a high level of safety and reliability.
  • Easy Disengagement: To close the knife, the user simply pushes the liner to the side, releasing the blade, which can then be safely folded back into the handle. Its simplicity and effectiveness contribute to the Blur's dependable performance.

Portability and Everyday Carry (EDC) Readiness

The Kershaw Blur 1670BLKST is built for continuous carry and immediate accessibility.

• Overall Dimensions and Weight:
  • Overall Length (OAL): 7.90 inches when open, providing a substantial yet manageable tool.
  • Closed Length: 4.50 inches, making it compact enough to carry comfortably in a pocket without being cumbersome.
  • Weight: A mere 3.90 ounces. This lightweight design, largely due to the aluminum handle, ensures it won't weigh down your pocket or gear, making it ideal for true everyday carry.
• Reversible Pocket Clip: The knife comes with a versatile pocket clip that can be configured for tip-up or tip-down carry, allowing users to customize their carry preference based on comfort and quick deployment style. This thoughtful design detail enhances its adaptability for different users and carry methods.

Kershaw's commitment to manufacturing the Blur series in the USA is a significant signal of quality and craftsmanship.
