N.Sutter Quercus NS01 — Frame Lock Folding Pocket Knife, D2 Blade, Swiss Design — Black Finish
Overview
The N.Sutter Quercus NS01 is a premium folding pocket knife by N.Sutter, a Swiss-design knifemaker whose signature — "Knives of excellence" — sums up the ambition: exceptional materials, precise execution, refined and timeless style. Every N.Sutter knife carries a unique serial number that acts as the piece's identity card.
The Quercus NS01 combines a 95 mm D2 steel blade — known for its hardness, exceptional edge retention and wear resistance — with a textured black G10 front scale and a steel frame-lock side. The build runs on ceramic ball bearings for an ultra-fluid flipper deployment. The result: an elegant, robust and perfectly balanced Everyday Carry (EDC) at 137 g, at a price remarkably competitive for this quality level.

NS01B All Black Specifics (Black Blade Variant)
- Integral tactical look: black blade + black G10 handle = fully assumed mono-tone aesthetic, aligned with modern tactical style.
- Enhanced anti-corrosion protection: the black coating protects the semi-stainless D2 steel from oxidation, particularly useful in frequent wet use (outdoor, marine, wet hunting).
- Note: the black coating may show more visible marks when cutting abrasive materials — this is normal and gives the knife a use-patina over time (like any coated blade).
About N.Sutter
N.Sutter — a Swiss-design signature dedicated to accessible high-end pocket cutlery.

What's Included
- 1 N.Sutter Quercus NS01 knife with unique serial number
- 1 original N.Sutter box
Care and Sharpening
- Wipe the blade after any wet use to prevent corrosion.
- Periodically oil the pivot with a fine cutlery oil (one drop).
- Sharpen with a fine ceramic stone (grit 1000/3000) or a guided system — recommended angle ~20° per side.
- All Black variant: sharpening removes the black coating on the cutting edge itself (normal behavior) — creating a fine silver line that testifies to the sharpening. No performance impact.
- Cleaning: microfiber cloth + fine oil. Avoid dishwashers and aggressive cleaners.
