The ZWILLING Diplôme bread knife is a professional bread knife with a serrated blade, designed to cut bread, baguettes and baked goods with a crispy crust precisely and easily, without excessively compressing the crumb.
The blade has a commercial length of 24 cm and a nominal length of approximately 23 cm. Its serrated edge is designed to penetrate effectively through even the more resistant crusts. The serrated profile also makes it easy to cut large baked goods.
The knife belongs to the ZWILLING Diplôme range, created in collaboration between ZWILLING and Le Cordon Bleu, the prestigious international culinary arts school. The series combines ZWILLING's expertise in knife manufacturing with Japanese-inspired craftsmanship and sharpening characteristics.
The blade is made of FC61 steel, a high-hardness steel reaching approximately 61 HRC. This contributes to good edge retention and cutting precision.
The knife is made in Japan and features an ergonomic black handle designed to provide a stable and comfortable grip during professional use.
The ZWILLING Diplôme bread knife is particularly suitable for bakeries, pastry shops, restaurants, delicatessens and professional kitchens, as well as for enthusiasts looking for a high-quality bread knife.

FAQs
What is the ideal length for a chef's knife?
The most common length for a chef's knife is 20 cm (8 inches), which is perfect for most kitchen tasks.
However, the ideal choice depends on several factors:
Hand size: Smaller hands handle 16–18 cm blades more comfortably, while larger hands may prefer a 21–25 cm blade.
Personal habits: Those who favor broad movements and long cuts might lean toward longer knives; those who prioritize precision or work in tight spaces might prefer a shorter blade.
Experience level: Beginners tend to choose shorter, more manageable blades, while professionals often prefer 21 or 24 cm knives for greater efficiency.
In short, there is no “perfect” size for everyone — the right length should be chosen based on comfort, control, and intended use.
What materials are used for knife blades?
Blades can be made of stainless steel (rust-resistant), carbon steel (very sharp but delicate), or ceramic (lightweight and razor-sharp but fragile). Premium knives often use Damascus steel or advanced alloys. Not sure which to choose? Contact us—AFcoltellerie has them all.
What are knife handles made of?
Handles can be made of wood (classic but delicate), plastic (durable and hygienic), or technical materials like micarta or G-10, which are extremely tough and non-slip even when wet.
European or Japanese knives: what’s the difference?
European knives are sturdier, with thick, curved blades for rocking cuts and tough ingredients. Japanese knives have thinner, harder blades for clean, precise slicing—but they’re also more fragile. In short: Europeans are durable and versatile, Japanese are sharp and surgical.
What’s the best knife for beginners?
A 20 cm chef’s knife is the most versatile option to start with. Paired with a paring knife, it covers most everyday kitchen needs.
What are the grooves (granton edge) on a blade for?
The grooves or “granton edge” reduce friction and prevent food from sticking to the blade. They’re especially useful with wet or soft foods like fish, cheese, or vegetables.
Are there knives for left-handed users?
Yes. Some single-bevel Japanese knives are made specifically for right- or left-handed use. Many universal knives, with a double bevel, work well for both.
