How Do You Clean a Folding Knife?
Sep 26, 2026
To clean a folding knife, wipe away residue after use and dry the knife thoroughly. Do not soak it or put it in a dishwasher. On SUWADA folding knives, the handle material changes the care slightly: natural wood should be kept away from prolonged moisture and strong heat, while the uncoated Damascus-steel handle should be kept clean and dry.
For normal everyday care, the goal is simple: remove dirt, avoid leaving moisture on the knife, and store it dry.
What is the safest way to clean a folding knife?
- Wipe the blade and handle clean after use.
- If moisture is present, dry the knife thoroughly rather than leaving it damp.
- Do not soak the knife in water.
- Do not put it in a dishwasher.
- Store it only when it is clean and dry.
These basic steps apply across the current SUWADA folding-knife range. The main difference is how the handle material should be treated.

How do you clean a folding knife with a wooden handle?
Keep a natural-wood handle dry and avoid soaking it. SUWADA's care data for the current wood-handled folding knives also advises avoiding dishwashers, strong heat and rapid changes in humidity.
This applies to the current:
SUWADA does not currently specify routine oiling for these folding-knife handles. The safest default is therefore to follow the maker's documented care: keep the wood dry and avoid unnecessary moisture and heat.
How do you clean the SUWADA Damascus folding knife?
The SUWADA Damascus folding knife has an uncoated forged Damascus-steel handle. Keep it clean and dry and avoid prolonged moisture.
One detail is worth repeating: on this model, the Damascus steel is the handle material. The blade is a separate Japanese cobalt stainless-steel component with a mirror-polished finish.
For more detail on its construction, see our Japanese folding knives and SUWADA Damascus guide.
Can you put a folding knife in the dishwasher?
No. SUWADA's care instructions for the current Micarta and natural-wood folding knives specifically say not to use a dishwasher. The combination of prolonged water, heat and detergent is also unsuitable for the wood-handled models and unnecessary for the Damascus model.
Can a folding knife get wet?
A small amount of incidental moisture is different from soaking the knife. If the knife gets wet, dry it thoroughly rather than leaving it damp. This is particularly important for the natural-wood handles and the uncoated Damascus-steel handle.
How often should you clean a folding knife?
There is no fixed schedule. Clean it whenever residue, fingerprints or moisture are left on the knife, and make sure it is dry before storage. Regular light cleaning is preferable to allowing dirt or moisture to remain on the knife for long periods.

Should I soak a folding knife to clean it?
No. SUWADA's current care guidance for the wooden models specifically says to avoid soaking, and the rest of the range should also be kept clean and dry rather than left wet.
Should wooden folding-knife handles be oiled?
SUWADA does not currently specify routine oiling for the natural-wood handles in this range. Follow the documented care instructions unless the manufacturer provides a more specific treatment recommendation.

Dry it thoroughly as soon as practical and do not store it while damp.
