Why You Should Never Put Your Knife in the Dishwasher

When you invest in a high-quality knife—especially a handcrafted Damascus steel blade like ours—it’s not just a kitchen tool, it’s a piece of craftsmanship. One of the quickest ways to ruin that craftsmanship? Tossing it into the dishwasher.

1. Dishwashers Can Damage the Blade

The high-pressure water jets and harsh detergents in dishwashers are rough on knife blades. Over time, they dull the edge, making your knife far less effective and requiring frequent sharpening.

2. Risk of Rust and Corrosion

Even stainless and Damascus steel can corrode if exposed to moisture for extended periods. Dishwashers create a hot, wet environment—perfect for rust to develop, especially if the knife isn’t dried immediately after the cycle.

3. Handle Damage

Many quality knife handles are made from natural materials like ram horn, camel bone, or wood. Dishwasher heat and detergent can cause them to warp, crack, or lose their finish. Once damaged, the handle is difficult—and often costly—to repair.

4. Safety Hazards

Placing a sharp knife loosely in a dishwasher can be dangerous. You risk cutting yourself when unloading, and the knife can shift during the cycle, potentially damaging other utensils (or itself).

5. Shortened Lifespan

Simply put—dishwashers drastically reduce the life of your knife. A well-maintained knife can last decades, but repeated dishwasher use can shorten its life to just a few years.

How to Properly Clean Your Knife

Wash by Hand: Use warm water, a mild dish soap, and a soft sponge.
Dry Immediately: Wipe the blade and handle dry with a clean towel.
Oil the Blade: Lightly oil the blade with food-safe mineral oil to prevent rust.
Store Safely: Keep your knife in a custom leather sheath, knife block, or on a magnetic strip.

Final Word:
A dishwasher might be convenient, but it’s the enemy of a good knife. Treat your blade with the respect it deserves, and it will reward you with years—if not a lifetime—of reliable performance.
