Kershaw 1670S30V Blur 3.4" Drop Point Folding Knife CPM S30V

The Kershaw 1670S30V Blur combines premium CPM S30V steel with SpeedSafe assisted opening for rapid deployment in tactical and everyday carry situations. This folding knife delivers professional-grade cutting performance with the reliability demanded by law enforcement, military personnel, and serious knife enthusiasts.

What Makes This Different

The CPM S30V stainless steel blade represents a significant upgrade over standard knife steels, offering superior edge retention and corrosion resistance. While most folding knives use 440C or 8Cr13MoV steel, the S30V powder metallurgy construction maintains sharpness 2-3 times longer under heavy use. The SpeedSafe assisted opening mechanism enables one-handed deployment in under 0.5 seconds, faster than traditional thumb stud systems.

Key Features

• CPM S30V premium stainless steel blade with 58-61 HRC hardness rating
• SpeedSafe assisted opening system with ambidextrous thumb studs
• 3.4-inch drop point blade with recurve edge geometry
• Stonewashed finish reduces glare and hides wear patterns
• Black anodized 6061-T6 aluminum handle scales
• Reversible pocket clip for tip-up or tip-down carry
• Liner lock mechanism with steel lockbar insert

Field testing demonstrates consistent lock-up strength and smooth action after thousands of opening cycles. The recurve blade profile excels at slicing tasks while maintaining control during detailed cutting work. Weather resistance testing shows no corrosion after 72-hour salt spray exposure, making it suitable for marine environments and harsh conditions.
