Your Opinel knife is built to work hard and age well. A few simple habits keep the blade sharp, the wood happy, and the action smooth. Whether cutting fruit on a hike, cooking at a campsite, or opening boxes at home, it’s nice to have a blade you can always rely on. But like any other quality product, Opinel knives also require some maintenance.
The good news is that maintaining your knife isn’t at all complicated. Following a few quick routines for stainless and carbon steel, wise advice for wood and polymer handles, and a handful of quick fixes for sticky pivots and light rust will be more than enough to keep your blades in tip-top shape for years to come.
Quick-start
-
Clean blades right after use, then dry them thoroughly before storing the knife. Moisture left on a blade or trapped in the handle usually causes trouble.
-
Do not immerse your knife in water; this could warp the wooden handle.
-
Cleanup is more straightforward for polymer handles, but we still recommend drying them completely.
-
A little drop of food-safe oil on the blade (and occasionally on the pivot) goes a long way.
Always cleaning your knives with great care helps you prevent accidentally cutting yourself!
How to Clean Stainless-Steel Blades
Stainless steel blades resist stains and drastic wear-and-tear, but prolonged contact with harsh environments (think acidic foods, salt water, heavy detergents) can still tarnish them, which is why a proper cleaning is necessary after each use.
-
Open your knife and rinse the blade under warm water.
-
Gently press and wipe the wet blade with a soft sponge plus a little dish soap.
-
Rinse the blade again, making sure it is clear of food residue and soap suds.
-
If your stainless steel knife has awooden handle, avoid rinsing the handle with a soaking stream and let the blade dry fully before closing. Stainless is low-maintenance, but wood still hates baths.
-
Polymer handles require less care, but they don’t provide the same iconic look or sensory experience as wooden handles do. However, if you’re looking for something that’s lower maintenance, it’s a viable alternative.
-
Carefully and thoroughly dry the blade and handle with a soft, absorbent cloth, and you’re golden.
How to Clean Carbon-steel Blades
Carbon steel blades cut beautifully and keep a keen edge, but maintaining them requires a little extra attention.
-
With the knife open, wipe the blade using a warm, damp sponge and mild detergent.
-
Rinse the sponge and wipe your blade again to remove any residue.
-
Immediately after your final rinse, dry the blade with a soft towel.
-
Apply a thin film of cooking or food-grade oil before dabbing off the excess and closing it. This step helps prevent oxidation and keeps the blade ready to go.
Carbon steel naturally darkens over time. Thatpatina isn’t a defect, but a normal, protective layer many fans actually like. If you’d rather keep things bright, you can reduce patina and remove light rust with a baking-soda-and-vinegar scrub or a gentle powdered cleanser, then finish off the process by drying and oiling.
Cleaning Your Knives in the Dishwasher
For folding knives, skip the dishwasher entirely.Heat, detergent, and clanging around with other dishes can permanently damage the wood and the folding mechanism. Hand wash and dry instead.
For kitchen and table knives, hand washing is still best. If youdo choose the dishwasher, use powdered detergent (not an all-in-one tablet) and remove the knives as soon as the cycle ends to dry by hand. If you notice faint spots afterward, remove them with a quick wipe of slightly-warmed white vinegar.
How to Maintain Wood and Polymer Handles
Wood handles (beech, olive, etc.)
-
Clean wooden handles with a quick rinse of warm water—do not soak them, and limit water exposure altogether as much as possible to prevent swelling or cracks.
-
After rinsing, let the handle air-dry completely.
-
Every so often, rub in a nourishing oil made for maintaining wood (knife-maintenance and cutting board oils are the best options, since they are food-grade) and let it sit on a dry, absorbent towel for a few hours.
Polymer handles
Although polymer handles are much more water-tolerant than wooden handles and can even withstand full dishwasher cycles, UV light can fade their color. Store polymer-handled knives away from direct sun (and yes, you can freshen color with a light oiling, too).
How to Clean the Lock and Pivot
If grit finds its way into the joint or the Virobloc® lock on your knife feels tight or loose after big humidity changes, clean andlightly oil the area. Our comprehensive step-by-step care guide also explains how to tighten or loosen the Virobloc® ring with pliers if wood expansion changes the fit.
After washing, leave your folding knives open to dry so moisture can escape from the pivot and collar.
Opinel Knife Field Care
-
Wipe the blade with a damp cloth, then dry immediately. If the knife got soaked, leave it open to dry thoroughly.
-
A microfiber cloth and a tiny bottle of food-grade oil weighalmostnothing. Toss them in your kit for on-the-go use as needed.
-
Sand, dust, and pocket lintcan and occasionallywill get in your knife. Fold a strip of fine sandpaper in half (or use compressed air) to clear debris inside the handle channel, then add a drop of oil to the pivot.
Common Mistakes to Avoid
-
DON’T immerse the knife in water (especially those with wood handles).
-
DON’T close a damp blade (this traps moisture and rusts your blade).
-
DON’T use harsh detergents or abrasive pads that scratch blades and damage wood.
