How to care for and sharpen a Damascus knife

Everyday care

A Damascus knife needs very little attention if you build a few habits from day one.

• Hand wash with warm water and a drop of washing-up liquid straight after use.
• Dry it completely with a soft towel before putting it away.
• Never put it in the dishwasher — heat, harsh detergent and knocks against other items dull the edge and can dull the pattern.
• Don’t leave it soaking in the sink or sitting wet on the draining board.

Choose the right board

Wooden and plastic chopping boards are kind to a fine edge. Glass, marble, slate and ceramic boards are harder than the steel and will blunt or chip it within a few uses. Avoid twisting the blade or using it to pry, scrape or cut through bone and frozen food.

Storage

Keep the knife on a magnetic strip, in a knife block, or in a blade guard. Loose in a drawer, the edge knocks against other utensils and dulls quickly — and it is a hazard for fingers.

Honing and sharpening

Honing and sharpening are different jobs. Honing straightens the microscopic edge between sharpenings; a few light strokes on a ceramic honing rod every week or two is plenty. Sharpening removes a little steel to create a fresh edge, and with regular honing is only needed every few months for home use.

A whetstone gives the best results on a hard VG-10 core. Soak or wet the stone as the maker instructs, then work the edge on a medium grit (around 1000) before refining it on a fine grit (around 3000–6000). Most Japanese-style Damascus knives are sharpened at roughly 15° per side. Avoid pull-through sharpeners, which remove steel aggressively and can scratch the layered surface.

Keeping the pattern bright

Over years of use the etched contrast can soften. Keeping the blade clean and dry preserves it, and a thin wipe of food-safe mineral oil before long-term storage adds a little extra protection.
