How to Clean and Care for Shun Kitchen Knives
Shun kitchen knives combine a very sharp, fine Japanese edge with layered or clad steels and several handle materials. Shun directs owners to hand wash immediately in warm, soapy water, rinse, and towel-dry rather than using a dishwasher or leaving a knife in the sink. The safest motion keeps the edge pointed away from the hand and the knife visible at all times. Cleaning preserves hygiene; sharpening, chip repair, and rust correction are separate maintenance jobs that should not be improvised with a rough scrubber.

Step-by-step instructions
Step 1: Clear a safe washing area
Remove dishes from the sink and place a dry towel beside it. Never drop a Shun knife into cloudy dishwater where the edge cannot be seen. Hold only one knife at a time by its handle with the blade pointing away from your body. If the handle or hands are greasy, wipe them before beginning so your grip stays secure.
Step 2: Wash immediately after use
Shun recommends prompt hand washing so acidic, salty, or starchy food does not dry onto the steel. Put a small amount of mild soap on a soft sponge, hold the blade flat and visible, and gently wipe the exposed side from spine toward edge—not along the sharp edge. Turn the knife over deliberately and repeat on the second side.
Step 3: Clean the bolster and handle
Wipe around the blade heel, bolster area, and handle junction without pressing a fingertip into the edge. Clean the handle with the same controlled, lightly soapy cloth unless the exact material has separate instructions. Do not soak wood-composite or natural handle materials, and do not pry at seams with a toothpick or metal tool.
Step 4: Rinse under warm or cool water
Rinse while keeping the edge facing away and the handle above the blade when practical. Shun cautions that very hot water can cook food particles onto the knife, while ordinary warm or cool water removes soap safely. Do not rest the edge against a metal sink or faucet; hard impacts can roll or chip the fine edge.
Step 5: Towel-dry immediately
Use a clean towel and wipe from the spine toward the edge, then dry the handle and junction. Do not pull a towel lengthwise along the edge or leave the knife on a draining rack. Immediate drying is important even on stainless and clad blades because food acids, salt, trapped moisture, and dishwasher chemistry can still cause discoloration or corrosion.
Step 6: Inspect under good light
Look for food film, water at the handle junction, a rolled edge, chips, reddish rust, or normal color change. Do not test sharpness with a fingertip. A clean blade may display its normal Damascus pattern or, on reactive-core series, a developing patina. Raised orange corrosion and smooth gray patina are not the same condition.
Step 7: Address light tarnish only with approved care
For natural tarnish, discoloration, or light surface rust, use Shun's Knife Care Kit or another method specifically approved for the exact blade finish. Work away from the edge and follow the product directions. Stop if corrosion is deep, near the cutting edge, or accompanied by pitting; Shun service can evaluate repair without thinning the blade through random abrasion.
Step 8: Store with the cutting edge protected
Place the completely dry knife in a clean block, sheath, in-drawer tray, or suitable magnetic rack. Do not toss it into a utensil drawer where the edge strikes metal and creates a hidden hand hazard. Clean and dry the storage slot too; returning a hygienic blade to a crumb-filled or damp block undoes the wash.
Step 9: Separate cleaning from sharpening
Washing removes food but does not restore a dull or chipped edge. Use Shun's sharpening service or a sharpening system appropriate to the blade angle and series. A honing steel designed for softer Western knives may not correct a Shun edge. Never run the blade through a dishwasher in the hope that heat will sanitize it; detergent, vibration, and rack contact can damage both blade and handle.
