The only kitchen knives you actually need
A fifteen-piece knife block is mostly storage for knives you will never pick up. Three knives do almost everything, and spending the same money on three good ones instead of fifteen mediocre ones changes how cooking feels.
The three
- Chef's knife, 20 cm (8 in). The one you reach for eighty per cent of the time. Onions, herbs, meat, squash. If you buy one knife, buy this.
- Paring knife, 8–10 cm. For work in your hand rather than on the board: peeling, hulling, trimming, deveining.
- Serrated knife, 20–25 cm. Bread, obviously, but also tomatoes and anything with a skin tougher than its inside. Serrated blades cannot be sharpened easily at home, so treat this as a consumable and replace it every few years.
A santoku can replace the chef's knife if you prefer a flatter blade and a push-cut style rather than a rocking motion. It is a preference, not an upgrade.
What to look for on the blade
- Full tang — the steel runs the whole length of the handle. You can usually see it as a strip between the handle scales. Partial tangs work loose eventually.
- Forged or stamped. Forged blades are thicker at the spine and heavier, and they hold an edge longer. Stamped blades are lighter and cheaper, and perfectly good for most home cooking. Neither is wrong; know which you are buying.
- Hardness (HRC). German-style steel sits around 56–58: tougher, easier to sharpen, duller sooner. Japanese-style sits around 60–63: holds an edge far longer, but chips if you twist it or hit bone.
- Balance. Hold it at the pinch grip — thumb and forefinger on the blade just in front of the handle. It should not tip forward or back.
Honing is not sharpening
This is the single most useful thing to understand. A steel hones: it straightens a rolled edge and takes ten seconds. Do it every few uses. A whetstone or pull-through sharpens: it removes metal and creates a new edge. Do that two or three times a year.
Test the edge on a sheet of paper held vertically. A sharp knife slices down cleanly. A honed but blunt knife tears. If honing no longer helps, it is time to sharpen.
The four things that ruin knives
- The dishwasher. Detergent is abrasive, the heat loosens handles, and blades knock against everything. Wash by hand, dry immediately.
- Glass, stone and ceramic boards. They blunt an edge in a handful of cuts. Use wood or plastic.
- The cutlery drawer. Edges chip against other metal. Use a block, a magnetic strip or blade guards.
- Twisting. Prying open squash or bone with the tip is how tips break.
Storage that suits your kitchen
A magnetic strip saves worktop space and dries the blade, but needs wall you are allowed to drill. A block is safest with children around. Blade guards in a drawer are the cheapest workable answer in a rented flat.
