Rockstead - Higo II knife F-HTI-ZDP - ZDP-189 & Titanium - PRIVATE COLLECTION - knife
PREVIOUSLY PURCHASED KNIFE, FROM A PRIVATE COLLECTION
* Origin: Acquired from a private seller, previously purchased
* Condition: Overall in excellent condition
* Availability on the market: Hard to find
* Sharpening: Factory-sharpened
* Marks on blade: A few small abrasions visible against the light on the mirror finish

* Inspected and Certified by our in-house laboratoryThe Rockstead HIGO II in titanium is not simply a high-end folding knife: it is the ultimate embodiment of Japanese philosophy applied to cutting, where every detail is pushed to the limits of perfection.
The minimalist, flawless titanium handle serves as a counterpoint to a ZDP-189 blade hardened to extreme hardness and finished with an almost unreal mirror polish. The result is not merely aesthetic: it is a living surface, capable of gliding through material with a smoothness and continuity that few knives in the world can offer.
Rockstead’s proprietary convex geometry does more than just cut: it separates, controls, and guides. It is a blade designed for those who recognize the difference between extreme sharpness and true long-term efficiency.
The HIGO II is an object for connoisseurs, where tolerances, treatments, and finishes are not mere technical specifications, but part of a precise language.

Inspected and Certified by our internal laboratorySHIN in Japanese means ‘trust’.
The SHIN is one of the largest folders in the Rockstead catalog and showcases all the typical and characteristic elements of the brand: aluminum handle with a pearl-radiant design, hardened anodization at 400 Vickers, and an insert of high-quality stingray leather (Samekawa).
This is a durable knife with strong cutting capabilities that maintains its edge for a long time. Even when used for rigorous cuts, the blade glides securely thanks to its particular sharpening.
The blade indeed has a HONZUKURI sharpening, convex on both sides, following the tradition of Japanese swords; this makes it both very sharp and sturdy, allowing it to cleanly cut a sheet of paper even after 1000 cuts through a very abrasive and resistant hemp rope.
A faithful companion for life, in which to place the utmost trust.
