TIESANJIAO Minimalist Hidden-Screw Custom EDC Folder – M390 Brushed DLC & Zirconium Damascus

Product Description

TIESANJIAO Minimalist Hidden-Screw Custom EDC Folder

Built around a clean, minimalist aesthetic, this custom TIESANJIAO folder combines precision machining with premium materials and a refined hidden-screw construction.

The blade is crafted from M390 powder steel and finished with a distinctive brushed DLC treatment, preserving subtle directional texture beneath the dark surface while giving the knife a sleek, understated appearance.

The handle is built on a TC4 titanium alloy structure and accented with striking Zirconium Damascus inlays. A matching Zirconium Damascus pocket clip completes the design, revealing layered patterns and shifting visual depth under different lighting conditions.

Its concealed hardware keeps the exterior exceptionally clean, allowing the geometry, materials, and machining to take center stage.

At only 2.550 oz / 72.29 g, the knife maintains a remarkably lightweight profile while retaining the premium feel expected from a high-end custom EDC folder.

Care & Maintenance

Wipe away moisture, fingerprints, sweat, and debris after use, and always keep the blade dry.

Apply a small amount of quality knife lubricant to the pivot and moving components periodically to maintain smooth operation.

Although the blade features a DLC finish, prolonged exposure to saltwater, acidic liquids, detergents, or other corrosive substances should be avoided.

Zirconium Damascus, titanium, and DLC surfaces may naturally develop minor scratches, wear marks, or subtle changes in appearance through normal carry and use.

Do not use aggressive abrasives, metal polishes, or harsh chemical cleaners, as they may damage the original finish.

For long-term storage, clean and dry the knife thoroughly and keep it in a cool, dry, well-ventilated place.
