Swiss Schmidt-Rubin Straight-Pull Rifle Database

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.

• 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).

N.Sutter — a Swiss-design signature dedicated to accessible high-end pocket cutlery. The house claims a "Knives of excellence" approach: noble materials (D2 and similar steels, G10, ceramic), precise execution and attention to detail rooted in Swiss watchmaking tradition. Each knife receives an individual serial number that makes it unique and traceable.

• 1 N.Sutter Quercus NS01 knife with unique serial number
• 1 original N.Sutter box

• 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.
