Your cutting board isn't dirty.
It's damaged.
Every knife stroke carves a groove. Grooves hold water, juice and bacteria — and no amount of scrubbing reaches the bottom of one. That's why wood grows mould and plastic goes grey. Katori is a single sheet of solid titanium.

It's the one tool you damage every time you use it.
Think about what a cutting board actually is. You take your sharpest knife and you drag it across the same surface, hundreds of times a week, on purpose.
Every one of those strokes leaves a groove. Raw chicken juice runs into the groove. Water follows it. The dishcloth doesn't. A week later the board smells, a month later it's stained, and at some point you throw it out and buy another one — and you call that normal.
That's why wood and plastic boards are sold the way they are: cheap, and often. They're consumables dressed up as tools. Titanium is hard enough that a kitchen knife doesn't carve into it — so there's no groove for anything to hide in, and nothing to replace next year.
Three ways a board goes bad
None of these are cleaning failures. They're what happens to a soft surface that gets cut, soaked and heated over and over.
Wood: mould in the grain
Cuts open the grain, the grain holds moisture, and in a humid kitchen that's all mould needs. It grows below the surface, which is exactly where a sponge can't go.
Plastic: stains and shedding
Every stroke shaves a little plastic off the surface. The scratches hold colour and smell for good — and the shavings have to go somewhere.
Glass and stone: a ruined edge
Surfaces that refuse to be cut take it out on your knife instead. Beating the mould problem isn't much of a win if it costs you the blade.
One board.
Rinse it, dry it, done.
Nothing to replace next year.
Four things a titanium surface does differently
Knife-friendly surface
Designed to take a blade without destroying its edge — unlike glass, marble or ceramic boards that stay pristine at your knife's expense.
Non-porous and odour-resistant
Nothing soaks in. Garlic, fish and raw meat rinse off the surface instead of settling into it, so yesterday's dinner doesn't turn up in today's.
It doesn't crack or warp
Solid titanium. It won't split along a grain, swell in the sink or buckle in the dishwasher — the three ways boards usually die.
Cleans in seconds
Water and a wipe for most jobs, dishwasher when you'd rather not. No oiling, no seasoning, no drying rack ritual.
99.89% pure titanium
Purity is the whole product, so it's worth seeing on paper. Katori's titanium was submitted to SGS — an independent testing and certification body — and the report is what you see here.

Built by someone who cuts on a board all day
Katori was created by chef Kaito Mason around a simple professional habit: in a working kitchen, a surface that can't be fully cleaned doesn't stay in service. Home kitchens inherited the opposite standard — boards that are replaced instead of cleaned.

"Finally something that doesn't cause me anxiety about potential cross contamination when I'm prepping chicken. Katori really doesn't scratch at all so no germs and bacteria get into it and then to other foods."
"Sooooo easy to clean. I just put mine in the dishwashr and it doesnt chip or warp or break like the wooden cutting boards do."
"Slicing everything on this board is such a delight. The knives do remain as sharp as a tack! I've been using it for months and had no problems with dulness!"
