DESCRIPTION
Stop sawing at your sourdough. A good bread knife doesn't press down and crush the crust - it glides through with almost no pressure, and the crumb stays intact below the serrated edge. At 10 inches, this one handles the full width of a pullman loaf, a long batard, or a round boule in a single stroke without the blade running out of room halfway across. It's also the right length for slicing layer cakes and ripe tomatoes where a shorter serrated blade drags and tears.
Length That Actually Matters
Most bread knives are 8 or 9 inches. That's fine for sandwich loaves but leaves you starting and stopping mid-cut on larger artisan breads and anything over 25 cm across. The 10-inch blade covers the full width of a standard batard in one pass, which means cleaner slices and less of the tearing you get when you have to restart. It's not a specialty tool for a niche use case; it's the size the job actually calls for.
73-Layer Damascus on a Powder Steel Core
The core is 14Cr14MoVNb powder steel, vacuum heat-treated to 62 HRC. Even on a serrated blade, the underlying steel hardness determines how long each serration stays sharp and how well it cuts through brittle crusts without rolling or dulling on the second dozen loaves. The Damascus cladding runs the full length of the blade on the flat spine side, and the rosewood handle sits well in a guide-grip for long horizontal strokes. Hidden tang construction keeps the balance forward where a bread knife needs it.

Serrated edge
Through crust without crushing the crumb.

- Doesn't crush soft bread or tomatoes
- Long 250 mm blade clears a whole loaf
A straight-edge knife on bread
- Tears and compresses the crumb
- Slips on hard crust
- Too short for a large loaf

Care & questions
How do I clean and care for it?
Hand-wash with warm soapy water and dry it straight away. Not dishwasher safe. Store it in the included wooden saya or on a magnetic strip to protect the edge.
Will the edge chip?
The 14Cr14MoVNb powder-steel core at 62±2 HRC holds a fine edge. Like any hard Japanese-style blade, keep it to food — avoid bone, frozen food and twisting.
Is it made in Japan?
No. It's hand-made in Yangjiang, China — the traditional Chinese city of knives — using a 14Cr14MoVNb powder steel equivalent to SG2/R2, as part of the Xinzuo × Mauro Uliassi collaboration.
What is a bread knife for?
Slicing anything with a crust or a soft interior — crusty loaves, soft bread, cakes and ripe tomatoes — where a serrated edge cuts cleanly without crushing.
Does it include a sheath?
Yes — a matching wooden saya is included in the gift box.
Can I have it engraved?
Yes — choose the engraving option in the buy box above before adding to cart.
