Specifications

The KAN-ZDP-SJ-SV represents a particularly restrained expression of Rockstead's approach to the gentleman's folding knife. Its handle features a uniform titanium-grey finish, giving the knife a clean, understated appearance without contrasting decorative accents. The subtle metallic tone allows the precision of the CNC-machined detailing and the symmetry of the design to speak for themselves.

The KAN holds a special place in Rockstead's history as the company's first slip joint folding knife, developed in response to requests from its customers. Its compact proportions, traditional mechanism, and carefully considered design offer a different interpretation of the Rockstead philosophy — one that places equal emphasis on cutting performance, mechanical refinement, and everyday elegance.

The Character of a Traditional Slip Joint
Unlike Rockstead's locking folders, the KAN uses a non-locking slip joint mechanism in which spring tension holds the blade open. A particularly distinctive feature is its precisely executed 90-degree half-stop. As the blade is opened or closed, it pauses at approximately 90 degrees with a distinct mechanical click. Additional pressure is required to overcome the spring tension before the blade continues to its fully open or closed position, marked by a second crisp click. The half-stop provides an additional measure of control during operation, while the two clearly defined clicks convey the precision of the fitted mechanism. Together with the knife's symmetrical design and deliberate, unhurried action, these details give the KAN the particular character of a finely made traditional gentleman's folder.

ZDP189 Steel and Honzukuri Blade Geometry
The KAN features a blade made from ZDP189 powder stainless steel, hardened to approximately 67 HRC and subjected to subsequent cryogenic treatment. Its Honzukuri geometry is Rockstead's distinctive convex grind, with both sides of the blade formed into carefully controlled, continuous curves. This geometry provides support behind the cutting edge while maintaining the refined cutting characteristics for which Rockstead knives are known. The blade is finished with Rockstead's signature mirror polish, extending across the convex surfaces all the way to the cutting edge. Achieving such a finish requires more than polishing the blade to a high shine. The geometry must be preserved throughout the finishing process, with particular attention paid to the smoothness and refinement of the cutting edge itself. This combination of high-hardness steel, convex geometry, and meticulous edge finishing remains at the heart of Rockstead's approach to cutting performance.

The Meaning of KAN
The name KAN (貫) comes from the Japanese verb tsuranuku (貫く), meaning “to carry through” or “to remain steadfast in one's convictions.” It expresses the philosophy behind Rockstead's craftsmanship: a consistent dedication to precision, cutting performance, and the principles that have shaped the brand.

A Choice of Two Distinct Finishes
With its uniform titanium-grey handle, the KAN-ZDP-SJ-SV offers a particularly discreet and timeless interpretation of the design. For gentlemen who prefer a more expressive appearance, Rockstead also offers the KAN-ZDP-SJ-BK, distinguished by its contrasting copper-toned spacer and matching pivot screw, which add a warm metallic accent to the knife.

Important: Slip Joint Mechanism
The KAN features a non-locking slip joint mechanism with a 90-degree half-stop. Although the half-stop provides additional resistance and control during opening and closing, it does not lock the blade in place. The knife is designed for two-handed opening and closing. Please ensure that you understand the characteristics and proper operation of a slip joint knife before purchasing.
