Kershaw Ken Onion Leek SpeedSafe Assisted Opening Liner Lock Knife - 3.00" CPM MagnaCut Stainless Steel Satin Modified Wharncliffe Blade - Laser-Engraved Hibiscus Flower Anodized Aluminum Handles (1660HI)
Overview & Heritage: Designed by Hall of Fame custom knifemaker Ken Onion and proudly manufactured in Tualatin, Oregon, USA, the Kershaw Leek (Model: 1660HI) is one of the most iconic and celebrated everyday carry folding knives in modern cutlery history. This special collector-grade execution pairs the Leek’s slim, surgical cutting profile with an exquisite, fade-resistant laser-engraved Hibiscus floral pattern across its anodized 6061-T6 aluminum scales. Upgraded with an elite American-made CPM MagnaCut stainless steel blade, the 1660HI combines stunning tropical aesthetic flair with apex powder-metallurgy performance, delivering an heirloom-quality EDC cutting tool engineered for supreme daily versatility.
Blade & Performance: At the heart of the 1660HI is a 3.00-inch modified Wharncliffe blade forged from revolutionary CPM MagnaCut stainless steel. Developed specifically for fine-edge cutlery, MagnaCut achieves an extraordinary balance of exceptional edge retention, high impact toughness, and near-total rust immunity. Precision ground to a razor-sharp plain edge with a fine, surgical tip, this blade slices with effortless efficiency through rope, packaging, tape, and dense cardboard. Featuring Kershaw’s patented SpeedSafe assisted opening mechanism, the blade deploys with lightning speed using either the ambidextrous flipper tab (extended tang) or dual thumb studs.
Handle, Lock & Safety Ergonomics: The handle is CNC-machined from lightweight, aircraft-grade 6061-T6 aluminum, finished with a resilient anodized coating that serves as the canvas for the detailed Hibiscus flower artwork. A sturdy stainless steel liner lock secures the blade in the open position, eliminating blade play during demanding push-cuts. For enhanced everyday carry safety, Kershaw incorporates their patented sliding Tip-Lock slider mechanism at the base of the handle, positively preventing accidental assisted deployment while tucked inside a pocket or bag. Complete with an integrated lanyard hole and a reversible pocket clip configured for tip-up or tip-down right-side carry, the 1660HI rides slim, flat, and comfortable at just 2.40 ounces.
*Bench Notes & Field Care Guidance:*
CPM MagnaCut is an ultra-pure American powder metallurgy stainless steel engineered to deliver maximum wear resistance with zero rust vulnerability under virtually all operating conditions. Keep the SpeedSafe torsion bar and pivot track cycling smoothly by periodically blowing out pocket lint with compressed air, followed by a single drop of high-grade synthetic pivot lubricant. Clean the laser-engraved anodized aluminum scales using warm water and mild dish soap to preserve the vivid detail of the Hibiscus artwork.
