3. Legendary ZDP189 Clad by VG10 Steel

At the heart of the RIN-ZDP is a high-performance blade crafted from ZDP189 clad by VG10 super steel. This combination offers unparalleled edge retention, extreme hardness, and excellent corrosion resistance, making it as reliable in function as it is stunning in form.

ZDP189 Blade Introduction

ZDP-189 is a high-carbon, high-chromium powder metallurgy steel renowned for its extreme hardness, often exceeding 64 HRC, which delivers peerless edge retention and aggressive cutting performance. This performance comes at a cost; its massive carbide volume makes the steel notoriously difficult to sharpen and increases brittleness, posing a risk of chipping under heavy lateral impact. Furthermore, while technically stainless, its high carbon content necessitates diligent maintenance to prevent oxidation, making it a specialized choice for precision cutting tasks rather than rough, heavy-duty utility.

This model design is image of "NAGURI" processing which is traditional Japanese technology that is used Japanese house's pillar, wall and a floor. Also, it was used many old traditional Japanese wooden building (Castle, Temple, shrine etc).
This model use "concealed clip system" that is movable clip for up to down. We have originally produced this system to eliminates the unconfortable feeling of the "clip feel" when gripping the handle. However, it turns out that a part of the mechanism of this " concealed clip system" conflicts with US patents No. 8,112,894 and 8,783,141.
We have been licensed to use these US patents after negotiations with Mr. Joseph Caswell, the US patent owner.

凛 RIN in Japanese mean's dignified.
