The Dew Hara NOAH-ZEN DH-20B is a new-in-box first-generation Japanese custom folding knife from Dew Hara, son of renowned Japanese knifemaker Koji Hara. Made in June 2016 and marked Serial Number 014, this knife represents one of Dew Haraโs earliest independent custom knife designs. It carries the precision, discipline, and visual restraint often associated with high-end Japanese custom knives, while also showing Dew Haraโs own futuristic design language.
This example was purchased by We Buy Knife Collections from a Japanese knife retailer that discovered three new-in-box first-generation Dew Hara NOAH-ZEN knives. The accompanying retailer provenance letter identifies the serial numbers as 006, 014, and 015, and states that these knives were part of Dew Haraโs early editions when he began his own custom knife brand in 2016. That provenance gives this piece added collector interest beyond the knife itself.
Dew Hara NOAH-ZEN DH-20B First-Generation Japanese Custom Knife
The Dew Hara NOAH-ZEN DH-20B blends Japanese custom knife artistry with a highly technical modern folder design. The blade is Vanadis 4E with an alkaline blackened finish, giving the knife a dark, purposeful look. The angular blade profile has a strong geometric presence, with a broad primary grind, dramatic swedge work, and a sharply defined tanto-inspired front end.
The handle is finished in gray stonewashed bead-blasted Duralumin, with black carbon fiber film inlays set into the sculpted cutouts. This creates a clean contrast between the matte metallic handle and the darker inlay material. Dew Haraโs own pivot screw design adds another distinct visual detail, tying the handle and blade together without making the knife feel overdone.
This is not a generic production-style folder. The NOAH-ZEN has the look and feel of a custom knife designed by someone raised inside a serious knifemaking family, but determined to build his own design identity. It has the mechanical presence of a tactical custom, the presentation value of a collector piece, and the provenance collectors want when evaluating early work from a maker.
Dew Hara, Koji Hara, and the NOAH-ZEN Design Lineage
Dew Hara grew up around knifemaking through his father, Koji Hara, and spent years studying his fatherโs techniques before developing his own knives. He also trained under Anthony Marfione for two years, giving his work a unique bridge between Japanese custom knife tradition and aggressive modern tactical design.
That influence shows clearly in the NOAH-ZEN DH-20B. The knife is technical and sculptural, but still controlled. The blackened blade, Duralumin handle, carbon fiber inlays, custom pivot, and layered construction all give the piece a deliberate, engineered look. It feels like a knife designed to stand apart from both conventional Japanese folders and typical American tactical customs.
New-In-Box Collector Condition With Original Documentation
This Dew Hara NOAH-ZEN DH-20B is new in the box despite being made in 2016. It includes the original Certificate of Authenticity, kimono-style cloth pouch, gift box, and Japanese retailer provenance letter. The COA identifies the model as NOAH-ZEN BLACK and lists the blade as Vanadis 4E with alkaline blackening, the handle as Zen-finished Duralumin with black carbon fiber film, the handle color as gray, and the liner material as 420 stainless steel.
The knife is dated 2016/06 and marked Serial Number 014. That low serial number, combined with the first-generation context and retailer letter, makes this a strong opportunity for collectors focused on Japanese custom knives, early Dew Hara work, Koji Hara family lineage, or high-end custom folding knives with documented provenance.
