How to Choose a Chef Knife: A Step-by-Step Decision Guide

Three checks that take 30 seconds. First, hold it in a pinch grip and check the balance: the knife should sit neutral without tipping forward or backward. Second, rest the blade flat on a cutting board and look at the contact: the curve of the belly should touch the board along its length without rocking or leaving a gap at the tip. Third, place the edge on a sheet of paper and draw it through without pressing: a sharp knife will slice the paper cleanly, and a factory edge on any knife worth buying should pass this test. If the store will not let you touch the knife or test the edge, the store is not helpful and you should order online with a return policy.

End-grain wood is the gold standard because the blade sinks between the wood fibers rather than striking a hard surface. Edge-grain wood and bamboo are the next best options. Plastic poly boards are acceptable and easier to sanitize, though harder on edges than wood. Glass, ceramic, granite, marble, and stone cutting surfaces destroy edges rapidly and should never be used with any knife you care about maintaining. The cutting board material affects how long your knife stays sharp more than any other single factor in your kitchen.

A full bolster, the thick collar of steel that extends from the spine all the way down to the cutting edge, prevents a whetstone from reaching the heel of the blade, which causes a bump to develop at the heel over years of sharpening as the rest of the edge is ground back but the heel cannot be. A half-bolster or tapered bolster exposes the heel for full-edge sharpening and is the better design for long-term maintenance. The Wusthof Classic has a full bolster. The Wusthof Classic Ikon has a half-bolster. The Ikon is the better design for sharpening, and it is the specific reason the Ikon is recommended as the upgrade.

In a store if possible, online with free returns if not. Holding the knife is the only way to evaluate balance and handle comfort, which are the two factors that determine whether the knife feels right for your hand. Brand, steel type, and blade geometry can be researched online, but comfort is personal and cannot be determined from a product page. If you live near a kitchen supply store like Sur La Table or a restaurant supply store, they typically let you handle the knives. If you are buying online, Amazon and most kitchen retailers accept returns on unused knives, so hold it, check the balance, and return it within the window if it does not feel right.
