The N.Sutter FIDELIS NS02A Black is a compact fixed blade knife by Swiss knifemaker N.Sutter, whose "Knives of excellence" philosophy translates here into a radical choice: the mechanical simplicity of a fixed blade, paired with one of the most respected stainless steels on the market — Alleima 14C28N (formerly Sandvik).

With its 145 mm overall length, 70 mm blade and featherweight 137 g, the FIDELIS NS02A is designed as a compact outdoor utility or a neck knife carried as a backup on pack or belt. It ships with a fitted Kydex sheath including a Kydex clip and a neck chain for maximum carry flexibility.

Like the entire N.Sutter line, each FIDELIS carries an engraved individual serial number — the piece's unique identity card, a guarantee of authenticity and a strong collectibility argument.

The Sandvik 14C28N (renamed Alleima 14C28N after the Sandvik group split) is a premium cutlery-grade stainless steel developed specifically for high-quality blades. Its worldwide-recognized strengths:

• Excellent edge retention for a stainless steel — typical hardness 58-62 HRC
• High ductility — impact and torsion resistance superior to ultra-hard steels
• Excellent corrosion resistance — true stainless, no compromise
• Remarkable sharpenability — resharpens easily, even in field conditions
• Fine grain — allows a very clean and durable edge

This steel choice places the FIDELIS in a different logic from the Quercus line (which uses semi-stainless D2): where D2 favors pure edge retention and wear resistance, 14C28N favors versatility, corrosion resistance and easy maintenance — perfect for a fixed blade destined for field, wet and demanding use.

• 1 N.Sutter FIDELIS NS02A Black knife with unique serial number
• 1 fitted Kydex sheath
• 1 Kydex clip (belt carry)
• 1 neck chain (neck knife carry)
• 1 original N.Sutter box

• 14C28N is a true stainless steel: low corrosion sensitivity, tolerates humidity well — a simple wipe after wet use is sufficient.
• Occasionally oil the blade (fine cutlery oil or Ballistol) for prolonged use in very humid or saline environments.
• Sharpen with a fine ceramic stone (grit 1000/3000) or a guided system — recommended angle ~20° per side. 14C28N resharpens particularly well, including in field conditions.
• Kydex sheath: rinse periodically with clean water to remove debris (sand, dirt, dust) — dry completely before reinserting to prevent prolonged blade corrosion.
• Knife cleaning: microfiber cloth + fine oil. Avoid dishwashers and aggressive cleaners.
