ZWILLING Professional S 4" Paring Knife – German-made, 15° Laser Edge, FRIODUR Hardened

ZWILLING's Professional S 4-inch paring knife is a precision German-made kitchen tool that delivers long-lasting sharpness, balanced handling, and exact control for small cutting tasks. Made in ZWILLING’s company-owned German factory, this compact paring knife pairs traditional forging with modern metallurgy. The blade is crafted from a high-carbon NO STAIN steel using SIGMAFORGE technology, then ice-hardened with FRIODUR treatment to increase resilience and edge retention. An ergonomic three-rivet polymer handle is perfectly bonded to the full tang, giving you dependable balance and everyday comfort.

How sharp is the blade and how long will it stay sharp?

The Professional S paring knife begins with a laser-controlled 15° edge per side and a precision-honed finish, so it arrives razor-sharp and ready to work. Ice-hardening (FRIODUR) and a 57 Rockwell hardness rating help the edge resist wear, extending time between sharpenings.

• 15° edge angle per side for fine slicing and clean peels
• 57 Rockwell hardness for superior edge retention
• FRIODUR ice-hardening reduces chipping and improves resilience
• Precision honing and laser-controlled edge for consistent sharpness

What materials and manufacturing methods are used?

This knife is precision-forged from a single piece of special-formula high-carbon NO STAIN steel using SIGMAFORGE technology for a dense, uniform blade profile. The combination of high-grade steel, ice hardening, and exacting laser-edge control reflects nearly 300 years of metallurgical development at ZWILLING.

• Special NO STAIN high-carbon steel for strength and corrosion resistance
• SIGMAFORGE one-piece forging for structural integrity
• FRIODUR ice-hardening for toughness and durability

How comfortable and safe is it to use for everyday tasks?

The ergonomic polymer three-rivet handle is bonded to a full tang to provide balanced weight and secure grip during detailed cutting tasks. The compact 4-inch blade gives precise control for peeling, trimming, and segmenting small fruits and vegetables without overreaching.

Is this knife easy to maintain and dishwasher-safe?

ZWILLING’s NO STAIN steel offers improved corrosion resistance, and the hardened FRIODUR blade is highly resilient. While the knife is labeled dishwasher safe, hand washing and immediate drying are recommended to preserve the edge and handle finish over time.

• NO STAIN steel reduces corrosion risk
• High hardness supports longer edge life between sharpenings
• Dishwasher-safe label—but hand wash for best longevity
• Regular honing and occasional sharpening maintain peak performance
