The Zwilling 34891 201 knife chef features powder metallurgical SG2 stainless steel construction with advanced CRYODUR hardening technology. This 20cm chef's knife delivers exceptional sharpness and durability for professional kitchen tasks.
Bob Kramer's distinctive design combines functionality with aesthetics. The Micarta handle provides superior grip control whilst stainless steel rivets ensure lasting construction. The blade's mirror finish creates a stunning visual appeal.
Weighing just 260g with balanced weight distribution, this knife excels at slicing, dicing and chopping. The ergonomic handle design reduces fatigue during extended use. Perfect for vegetables, meat and fish preparation with clean, precise cuts every time.
SG2 powder metallurgical steel contains higher carbon content and chromium levels than conventional stainless steel. The powder metallurgy manufacturing process creates a more uniform grain structure, resulting in superior edge retention and corrosion resistance. This steel can achieve higher hardness levels whilst maintaining toughness, meaning the blade stays sharper longer and resists chipping better than standard kitchen knives.
CRYODUR is a specialised cold treatment process that subjects the blade to extremely low temperatures after initial heat treatment. This process refines the steel's crystalline structure, increasing hardness and durability. The cold treatment eliminates retained austenite in the steel, creating a more stable blade that maintains its edge geometry and sharpness through extended use in demanding kitchen environments.
Whilst Micarta is technically dishwasher safe, hand washing is recommended to maintain the handle's appearance and longevity. The composite material won't degrade in dishwashers, but the high heat and harsh detergents can gradually affect the surface texture. Hand washing with warm soapy water and immediate drying preserves the handle's grip properties and prevents any potential loosening of the riveted construction over time.
The blade's profile excels at both rocking and push-cutting techniques. The curved belly allows efficient rocking motions for chopping herbs and vegetables, whilst the straight section near the tip handles precise slicing tasks. The blade height provides excellent knuckle clearance for rapid chopping and the thin profile reduces drag when slicing through dense ingredients like root vegetables or proteins.
With proper care, the SG2 steel maintains its factory sharpness for several months of regular home use. Professional kitchens might require honing every few weeks depending on usage volume. The superior edge retention means less frequent sharpening compared to softer steels. When sharpening is needed, use whetstones rather than pull-through sharpeners to maintain the blade's precise geometry and avoid damaging the premium steel.
This Bob Kramer design features premium SG2 steel compared to standard German steel used in most Zwilling knives. The CRYODUR hardening process and Micarta handle construction represent higher-end materials and manufacturing techniques. The blade geometry follows Japanese-influenced design principles, creating a thinner, sharper profile than traditional German chef knives whilst maintaining the durability Zwilling is known for.
Yes, the 20cm blade length and robust construction handle most butchery tasks effectively. The SG2 steel's toughness prevents chipping when cutting through joints and cartilage. However, avoid using it on frozen foods or bones, as this can damage any kitchen knife. For breaking down whole chickens, fish filleting and general protein preparation, this knife performs excellently whilst maintaining its sharp edge.
Wash immediately after use with warm soapy water and dry completely to prevent water spots on the mirror finish. Store in a knife block or magnetic strip to protect the edge. Occasional honing with a steel rod maintains the edge between sharpenings. Avoid cutting on glass, stone, or metal surfaces which can dull the blade. With proper care, this knife will maintain professional performance for decades of kitchen use.
