How Many Kitchen Knives Do You Need?

Three. A 210 mm gyuto for almost everything, a second shape for the jobs the gyuto is worst at, and one cheap tough knife you are allowed to abuse. Buy them in that order, and buy a sharpening stone before you consider a fourth knife — a sharp three-knife kitchen beats a dull seven-knife one at every single task.

The reason this question gets a confused answer is that the people answering it mostly sell knife blocks. A 15-piece set looks like better value than three knives at the same price, and it is not: the money is spread across six steak knives, a pair of shears, a honing rod of unknown quality, a wooden block and two or three blades that will never leave it.

This is 80 percent of your cutting. It has a tip for detail work and seaming meat, a belly for rocking through herbs, and enough length to finish a slice in one pass. Buy the best one you can afford, because every improvement here compounds across every meal you cook. The Tojiro DP F-808 at around $75 is where the value is densest; our gyuto roundup covers the alternatives.

Which one depends on what you cook. There are only two sensible answers:

• A nakiri, if your board is mostly vegetables. 45 mm tall, 1.8 mm at the spine, flat all the way along, so slices separate completely and your knuckles clear a cabbage. It is the biggest upgrade available to a kitchen that already owns a chef's knife. Gyuto versus nakiri sets out the trade.
• A petty at 120 to 150 mm, if you do more small work. Shallots, garlic, segmenting citrus, trimming a steak, anything where a 210 mm blade is unwieldy in the hand. Petty versus paring knife explains why the longer small knife is usually the better buy.

This is the knife that keeps the other two alive. Bone-adjacent work, frozen food, squash with a stubborn skin, prying something, the knife you hand to a guest who offers to help. A Victorinox Fibrox Pro at 56 HRC rolls instead of chipping and comes back on a rod in seconds, which is exactly what you want from a blade whose job is to absorb abuse.

Skipping knife three is the most common and most expensive mistake. Every chipped Japanese knife we hear about came from a job that should have gone to a cheap tough blade. Why knives chip is the short version.

A King KDS 1000/6000 combination stone changes all three of your knives at once, permanently. There is no fourth knife that does that. Our stone picks are here.

• A bread knife, if you buy crusty loaves. Nothing else does the job and it never needs sharpening.
• A boning or utility knife, if you butcher at home regularly.
• A long slicer, if you carve roasts more than a few times a year. Otherwise a sharp gyuto drawn in one stroke is close enough.

Three knives: a 210 mm gyuto, a second shape chosen for how you actually cook, and a cheap tough beater. Add a 1000/6000 stone before anything else, because it upgrades every knife you own at once. Everything beyond that is preference, and preference is fine — just buy it knowing it is preference rather than need. If you are at the start of this, start with the first-knife guide, and the shape glossary covers what each of these blades is called and why.
