Before you buy
- No main kitchen knife is for cutting through bone or frozen food. Use a heavy meat cleaver or a saw for bone, and thaw first.
- Wash by hand and dry at once. A dishwasher dulls the edge and can damage the handle.
- A sharp knife is safer than a dull one: it needs less force and slips less. Curl the fingertips of your guiding hand under.
- A honing rod straightens an edge; it does not sharpen a dull one. On hard Japanese-style blades use a ceramic rod or a stone, not a grooved steel one. Sharpening removes metal and is done far less often.
- Keep knives where children cannot reach them, and check the age rules for buying knives where you live.
The three types, in short
Western (German-style) chef's knife, 20 cm / 8 inch
A curved edge for a rocking cut, a thicker blade and usually softer steel. It forgives rough use, goes through dense vegetables, and is easy to bring back with a honing rod.
It cannot: It is heavier and thicker than the other two, so very fine slicing takes more effort, and its edge needs honing more often.
Japanese-style chef's knife (gyuto), 21 cm / 8.25 inch
A thinner, lighter blade, usually of harder steel, with a flatter edge. It usually takes a keener edge and holds it longer, which suits push cuts, fine slicing and fish.
It cannot: Hard, thin steel can chip. It is not for bones, frozen food, hard squash or twisting in a cut.
Santoku, 17 cm / 7 inch
A shorter, wide blade with an almost flat edge, made for straight up-and-down and push cuts. It is easy to control on a small board and in a small hand.
It cannot: The flat edge does not rock well, and the short blade struggles with large items such as a whole cabbage or a melon. Many santoku are thin, hard steel too: no bones, no frozen food, no twisting.
