The Tefal JO Knife Series 5PC Set combines Jamie Oliver's culinary expertise with Tefal's engineering precision. This professional knife collection features five essential blades crafted from German stainless steel.
Each knife undergoes ice hardening treatment - a thermal shock process dropping temperatures from 1000°C to -120°C. This creates exceptionally durable and sharp cutting edges that maintain their performance over time.
The set includes 20cm chef knife, 20cm bread knife, 16.5cm santoku knife, 12cm utility knife and 9cm paring knife. All knives feature acacia wood handles and store securely in the included FSC-certified acacia wood block weighing 2.76kg.
The ice hardening process subjects the German stainless steel blades to extreme temperature shock, dropping from 1000°C to -120°C rapidly. This thermal treatment restructures the steel's molecular composition, creating harder, more durable blades that hold their sharp edge significantly longer than standard knives. The process also increases the blade's resistance to chipping and dulling during regular use.
Customer reviews consistently report the knives maintaining excellent sharpness for 10+ months with daily use. The ice hardening treatment and quality German steel construction mean these knives require minimal sharpening compared to standard kitchen knives. Most users find they can go 12-18 months before needing professional sharpening, depending on usage frequency and cutting techniques.
Yes, the acacia wood block weighs 2.76kg making it extremely stable during knife insertion and removal. The substantial weight prevents tipping or sliding on worktops, whilst the FSC-certified acacia wood provides natural durability and resistance to moisture damage. The block's dimensions of 25.8 x 12.8 x 37.8cm offer a stable footprint for kitchen safety.
All five knives are dishwasher safe, though hand washing is recommended to maintain optimal blade condition. The stainless steel construction resists corrosion whilst the sealed acacia handles won't split or degrade in dishwasher cycles. However, the high heat and harsh detergents can gradually dull any knife edge, so hand washing extends sharpness retention.
The 20cm chef's knife features a curved blade ideal for rocking motions when chopping herbs and vegetables, whilst the 16.5cm santoku has a straighter edge perfect for precise slicing and dicing. The santoku's shorter length offers better control for detailed work, whilst the chef's knife handles larger ingredients and heavy-duty chopping tasks more effectively.
The acacia wood handles are ergonomically shaped and properly weighted to reduce hand fatigue during long cooking sessions. The natural wood provides excellent grip even when wet, whilst the balanced design ensures the knife feels secure in your hand. Most users report comfortable use for 30+ minutes of continuous food preparation without strain.
Purchasing this 5-piece set provides significant cost savings compared to buying equivalent quality knives individually. The set covers all essential kitchen cutting needs whilst ensuring consistent quality and design across all blades. The included storage block adds further value, as quality knife blocks typically cost £40-60 separately.
Tefal provides standard manufacturer warranty coverage against defects in materials and workmanship. The ice hardened German steel construction and quality acacia wood components are built to last decades with proper care. Customer reviews indicate excellent long-term durability with minimal reported quality issues over extended use periods.
