How to Choose Kitchen Knives: A Complete Buying Guide

Buy one 8-inch chef’s knife first, size the handle to your hand, and add specialty blades only when a real task demands them.

Most home cooks do 90% of their work with a single well-chosen chef’s knife. Pick that one blade correctly, then add only what your cooking requires. Victorinox’s US cutlery hub frames the decision around “what to consider when buying a knife”: task first, then handle, then length, then steel.

Which Knife Should You Buy First?

The chef’s knife comes before anything else — the everyday workhorse for mincing herbs, crushing garlic, and prepping meat, which is why both Victorinox and WÜSTHOF build their lines around it. Victorinox calls it a multipurpose tool for herbs, garlic, and small meat prep.

A paring knife for small work and a serrated bread knife are the only additions most kitchens need. Everything past those three — boning knives, cleavers, fillet knives — waits until a specific recipe demands it.

• Buy first: 8-inch chef’s knife
• Add second: 3–4 inch paring knife
• Add third: serrated bread knife
• Skip for now: anything tied to a dish you rarely cook

Blade Length and Handle Fit

Match the blade to your hand and counter space, not to a photo of a professional kitchen. WÜSTHOF’s US line lists 6-inch, 8-inch, and 10-inch chef’s knives, and each size solves a different problem.

A 6-inch blade suits smaller hands, tighter kitchens, and cooks who mostly chop vegetables. The 8-inch is the standard all-purpose size — enough length to rock through an onion, still controllable on a crowded board. A 10-inch blade earns its place for larger hands or high-volume prep, but needs real clearance around the board to be safe.

Handle fit matters as much as length. Hold the knife before you commit: fingers should wrap the handle without your hand crowding the bolster, and the grip should feel secure when your palm is slightly damp. WÜSTHOF’s Germany storefront lists sizes in both centimeters and inches — a 20 cm chef’s knife is the same as an 8-inch, worth knowing when comparing listings across regions.

How Much Should You Spend, And Which Line?

Steel quality and construction set the price tier. On WÜSTHOF’s US pages, Gourmet is the lower-cost line, Classic and Classic Ikon sit midrange, and Ikon, Performer, and Amici land at the premium end.

Current US prices: a Gourmet 6-inch chef’s knife runs about $80 and an 8-inch about $100, while Classic sits at roughly $135 for 6 inches and $170 for 8. Classic Ikon lists near $128 for the 6-inch and $200 for the 8-inch, and Performer reaches about $295 for an 8-inch.

None of those numbers travel across borders. WÜSTHOF’s Canada store shows the Classic 8-inch at $220.00 CAD and the 6-inch at $190.00 CAD, and its Germany pages list euro pricing on the same models. Always check the storefront for your market.

For specific models that hold up in daily use, this tested roundup of the best kitchen knives worth buying covers real-world picks across price tiers.

Should You Buy A Knife Set Or Single Knives?

Single knives usually win unless you’re outfitting a kitchen from zero. Sets bundle a fixed mix of blades, often including pieces you’ll rarely touch. WÜSTHOF’s current set lineup: a Gourmet 2-piece chef’s knife set lists at $115, a Gourmet 3-piece set at $185, a Classic 3-piece chef’s knife set at $325, and a Classic 5-piece chef’s knife set at $505.

Read the contents before you buy — WÜSTHOF’s sets pages also list block and steak bundles, so not every “set” is a starter set. A bundled set only makes sense when you’d genuinely use most of the blades inside it.

Whichever route you take, verify the current price and availability on the brand’s own storefront for your region. Sale prices appear on some product pages alongside crossed-out regular prices, so note whether the number you see is the sale price or the standard one.
