Robert Welch Professional Home Chef Knife Set (3 Piece, Black)

What makes the ice hardening process different from standard steel treatment?

Ice hardening involves cooling the German 1.4116 stainless steel to extremely low temperatures during manufacturing. This process refines the steel's molecular structure, creating a harder and more resilient blade that holds its edge significantly longer than conventionally treated steel. The result is exceptional sharpness retention and improved cutting performance over the knife's lifetime.

How does the full tang construction improve knife performance?

Full tang construction means the steel blade extends completely through the handle, rather than just being attached to it. This provides superior balance as the weight is distributed evenly throughout the knife. It also eliminates the weak point where blade meets handle, preventing breakage during heavy use. The robotically engineered tang ensures precise weight distribution for optimal control.

Are these knives suitable for professional kitchen use?

Yes, these knives are designed for professional standards. The forged German steel construction, ice hardening treatment and full tang design meet commercial kitchen requirements. The seamless handle construction aids hygiene compliance, whilst the balanced weight distribution reduces fatigue during extended use. Many professional chefs prefer this style of European-profile blade for its versatility.

What specific tasks is each knife in the set designed for?

The 12cm santoku excels at precision slicing of vegetables, fruits and boneless meats with its straight edge and lightweight 133g design. The 14cm kitchen knife handles general tasks like paring, trimming and detailed work at 125g. The 18cm chef's knife at 214g is perfect for chopping, dicing and rocking cuts through larger ingredients, providing the weight needed for efficient processing.

How do I maintain the sharpness of these knives?

The ice-hardened steel maintains sharpness longer than standard knives, but regular honing with a steel rod will keep edges aligned. For sharpening, use a whetstone or professional sharpening service rather than electric sharpeners which can damage the blade geometry. Hand wash and dry immediately after use and store in a knife block or magnetic strip to protect the edges.

What is POM handle material and why is it used?

POM (Polyoxymethylene) is a high-performance engineering plastic known for its durability, chemical resistance and dimensional stability. It's injection moulded directly onto the tang, creating a molecular bond that's virtually unbreakable. POM is non-porous, preventing bacteria growth and maintains its shape and colour over time. It's also dishwasher safe, though hand washing is recommended.

How do these compare to Japanese knife styles?

These knives feature European blade geometry with deeper profiles and straighter cutting edges compared to traditional Japanese designs. The German steel is harder than most European knives but softer than Japanese carbon steel, making it easier to maintain whilst still holding a sharp edge. The full tang construction and heavier weight suit Western cutting techniques better than lighter Japanese alternatives.

What age restrictions apply to purchasing these knives?

UK law requires age verification for knife purchases. You must be 18 or over to buy this set. Online age verification checks are mandatory and delivery drivers may request photographic ID showing your date of birth. The driver inputs your birth year into their device but doesn't retain personal information after delivery. This applies to all knife sales in the UK.
