Specifications

Developed in response to numerous requests from Rockstead customers, the KAN-ZDP-SJ-BK marks the introduction of the first slip joint folding knife in the company's history.
At the heart of the KAN's character is its traditional slip joint mechanism, distinguished by a carefully executed half-stop feature. Unlike a locking folder, the blade is held in the open position by spring tension rather than a mechanical lock, and is intended for deliberate, two-handed operation.

During both opening and closing, the blade comes to a distinct stop at approximately 90 degrees, accompanied by the first precise click of the mechanism. Additional pressure is required to overcome the spring tension and continue the movement, until a second crisp click marks the fully open or closed position. This intermediate stop provides an additional measure of control, helping to prevent the blade from folding shut in a single uninterrupted movement.

Yet the appeal of this mechanism extends beyond its practical function. The symmetry of the design, the unhurried, assured movement of the blade, and the two distinct clicks of its precisely fitted components create a sense of mechanical refinement rarely associated with an ordinary folding knife.

The KAN-ZDP-SJ-BK is distinguished by its copper-toned spacer between the handle scales, complemented by a matching pivot screw. These warm metallic accents provide a subtle contrast to the handle, lending the knife a distinctive character and understated charm. Combined with Rockstead's signature mirror-polished blade, these qualities embody the manufacturer's vision of a gentleman's knife — a refined folding knife whose understated elegance, mechanical precision, and considered operation make it particularly well suited to everyday carry. For those who prefer an even more restrained aesthetic, Rockstead also offers the KAN-ZDP-SJ-SV, with a more understated design.

The blade is made from ZDP189 powder stainless steel, hardened to approximately 67 HRC and subjected to subsequent cryogenic treatment. It features Rockstead's Honzukuri blade geometry, a complex, smoothly contoured convex grind that demands exceptional precision in shaping and finishing.

The blade receives Rockstead's distinctive mirror polish, extending across the convex surfaces all the way to the cutting edge. This meticulous finishing is far more than an aesthetic consideration. It is fundamental to Rockstead's approach to cutting performance, where blade geometry, surface refinement, and edge quality are treated as integral parts of a single system.

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 reflects Rockstead's commitment to its principles of precision, craftsmanship, and cutting performance.

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 is not a blade lock. The knife is designed for two-handed operation.
