How to Care for a Knife Set | Keep Blades Sharp

Care for a knife set by hand-washing with mild soap and warm water, drying immediately, and storing blades fully dry and protected.

For the full breakdown, see our best 5 Piece Knife Set guide.

Most knife damage happens in the sink and the dishwasher, not on the cutting board. Between the heat cycles, harsh detergents, and blades knocking against other metal, a dishwasher dulls edges and can pit the steel. The good news is that caring for a quality set takes about two minutes per knife, and the payoff is a sharper, safer blade that lasts for years.

Below is the care routine used by three well-known makers — Buck, Victorinox, and GLOBAL — plus the sharpening basics and the storage mistakes that quietly ruin blades.

The Hand-Washing Routine That Protects Edges

Every knife maker agrees on the core routine: wash soon after use, dry immediately, and never let the blade air-dry. The steps take seconds and prevent most corrosion and dulling.

• Rinse the blade under warm running water right after use.
• Wash with mild dish soap and a soft sponge or cloth, cleaning the handle too.
• Rinse off all soap residue thoroughly.
• Dry immediately with a soft cotton or linen towel.

Victorinox’s care guidance is specific: rinse under cold running water after use and dry with a cotton or linen towel, never letting the knife air-dry. GLOBAL’s instructions call for warm soapy water, a thorough rinse, and a full towel-dry.

Three things to avoid at the sink: long soaks, bleach or chlorine cleansers, and harsh detergents. GLOBAL warns against bleach and chlorine-based cleaners outright, and soaking can weaken handle materials and leave moisture trapped against the steel.

The Right Way To Dry And Store Knives

Drying and storage are where most people undo their good washing habits. A blade stored wet or damp is a blade that corrodes and dulls faster.

Dry each knife completely before it goes away, including the handle and the tang area where the blade meets the handle. Then store it so the edge is protected and blades never knock against each other. Public-health guidance on knife safety lists wooden blocks, wall-mounted magnetic strips, racks, and trays as proper options — anything that keeps each edge separated and supported.

Never toss knives loose into a drawer. The blades collide, nick each other, and become a hazard when you reach in blind.

Sharpening Basics: Angles, Stones, And Serrations

A sharp knife is safer than a dull one because it cuts with less force and slips less. Dull blades are the ones that slide off tomato skins and into fingers.

Serrated blades need a different tool. A tapered rod or file sized for the serrations is correct, and you sharpen only the serrated side, not the flat back. Using a standard whetstone on a serrated edge will flatten the scallops and ruin the cutting geometry.

When sharpening any blade, match the tool to the steel. Hard Japanese blades like GLOBAL take well to a whetstone; softer Western blades often do fine with a honing rod between full sharpenings. The wrong tool at the wrong angle does more harm than not sharpening at all.

Everyday Mistakes That Ruin Knife Sets

Most knife damage comes from a handful of repeatable habits. Here is what to stop doing:

• Running knives through the dishwasher, which dulls edges and damages handles.
• Letting knives air-dry on a rack, which leaves water on the steel.
• Soaking knives in the sink or leaving them wet before storage.
• Using bleach, chlorine cleaners, or abrasive detergents.
• Storing blades before they are fully dry.
• Sharpening at the wrong angle or with the wrong tool for the blade type.

When you wash and dry, keep fingers clear of the edge and point the blade away from your body. It sounds obvious, but it is the most common kitchen cut in the care routine itself.
