Leek Assisted Opening Pocket Knife – Partially Serrated – Kershaw KS1660STX

The Kershaw Leek has become one of the most recognizable everyday carry knives on the market. Designed by Ken Onion, its slim profile, quick assisted opening, and versatile blade have made it a favorite among professionals, tradesmen, and everyday knife users for more than two decades.

The KS1660STX adds a partially serrated cutting edge, giving you the versatility of a plain edge for clean slicing and serrations for rope, webbing, and other tough materials.

Description

The KS1660STX, designed by award-winning knife maker Ken Onion, the Leek combines sleek styling with dependable everyday performance. Its slim profile rides comfortably in the pocket, while Kershaw's SpeedSafe® assisted opening system allows for fast, one-handed deployment using either the thumb stud or flipper.

The 3-inch modified drop point blade is crafted from Sandvik 14C28N stainless steel, offering an excellent balance of edge retention, corrosion resistance, and ease of sharpening. The partially serrated edge increases cutting versatility by making quick work of fibrous materials while retaining plenty of plain edge for precision cutting.

The stainless steel handle gives the knife its signature slim appearance without sacrificing durability. A frame lock securely holds the blade open during use, while the Tip-Lock slider helps prevent accidental opening during pocket carry. A reversible pocket clip allows comfortable tip-up carry for both right- and left-handed users.

Collector Notes

Its combination of lightweight construction, SpeedSafe® assisted opening, and practical blade design has made it a favorite among both new knife owners and longtime collectors.
