N.Sutter Quercus NS01A Black — Frame Lock Folding Pocket Knife, D2 Blade, Swiss Design

Overview

The N.Sutter Quercus NS01A Black 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 NS01A 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 Quercus is aimed at shooters, professionals and demanding enthusiasts seeking a reliable, distinctive and stylish pocket knife, in a price range remarkably accessible for this level of quality craftsmanship. A daily companion capable of everyday cutting tasks as well as more technical outdoor, hunting, workshop or tactical uses.
