Kershaw Leek 1660BLKW Overview
The Kershaw Leek 1660BLKW Pocketknife takes the renowned Ken Onion design and gives it a rugged, pre-worn aesthetic with a full BlackWash finish. Moreover, the 3-inch blade is crafted from premium Sandvik 14C28N stainless steel, a high-performance alloy that offers a superior combination of hardness, edge retention, and corrosion resistance. Furthermore, the distinct BlackWash™ finish on both the blade and handle provides a vintage, broken-in look that helps hide scratches and fingerprints better than standard satin or bead-blasted coatings.
Mechanism and Reliability
The patented SpeedSafe® assisted opening system allows for smooth, one-handed deployment using the ambidextrous flipper or dual thumb studs. In addition to its rapid action, the knife features a robust frame lock and a secondary Tip-Lock slider to ensure the blade remains securely locked during use and transport. Because of its slim profile and 3.0-ounce weight, this folder is an excellent choice for those who want a capable tool that doesn’t bulk up their pocket. If you like the rugged performance of this model but prefer the classic stainless look, we highly recommend checking out the original Kershaw Leek 1660 for a cleaner aesthetic.
Handle Design and Ergonomics
Furthermore, the modified Wharncliffe blade offers a razor-sharp tip that is perfect for detail work, while the straight edge provides excellent slicing control. Additionally, the handle is machined from durable 410 stainless steel, creating a unified, metallic frame that is tough enough to handle daily abuse. Consequently, the reversible pocketclip allows for versatile tip-up or tip-down carry, making it adaptable to your specific gear setup.
