If you want to protect your knives, the single most effective change you can make is to use and properly care for a wooden chopping board, not glass or stone. A well maintained board like the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg) can help your knives stay sharper for 2 to 3 times longer than if you cut daily on hard worktops or ceramic boards.
Why wooden chopping boards protect your knives
Knife edges are incredibly thin, often less than 0.5 mm at the tip. Every time you cut, that edge meets resistance. On very hard surfaces like glass or granite, the steel edge is forced to flatten or chip. On a well cared for wooden cutting board, the surface has a little “give”, so the edge sinks in slightly instead of crashing into something harder than the blade.
The right wooden board helps in three specific ways:
- Gentle on edges: Woods like bamboo and acacia are firm enough for safe chopping but not so hard that they blunt the edge quickly.
- Self healing grain: Fine knife marks tend to close up slightly, so you don’t get deep grooves that catch and twist the blade.
- Controlled moisture: A properly oiled board does not swell or warp, so your knife meets a flat, stable surface every time.
Daily care routine that protects both board and knives
Looking after your wooden kitchen boards is simple if you follow the same steps every time you use them. This consistency is what keeps both the board and your knives in good condition for years.
Step 1: Use the right side for the right job
If you use a double sided board, dedicate one face for meat and fish, and the other for fruit, vegetables and bread. The Deer & Oak wooden chopping board range is designed to be reversible, so you can keep one side looking smarter for serving.
- Use the smoother, less marked side for slicing cooked meats, cheese and bread.
- Keep the more worn side for tougher chopping like root vegetables.
This avoids deep cross scoring in one area, which can catch the knife edge and twist it off line.
Step 2: Clean immediately after use
Leaving food to dry on the board forces you to scrub harder later, which can damage the surface and your knife edge. Instead:
- Scrape off food with a plastic scraper or the back of a butter knife. Avoid metal scrapers with sharp corners.
- Wash by hand in warm water (around 40–45°C) with a mild washing up liquid.
- Use a soft sponge or cloth, not a steel scourer.
Never put wooden chopping boards in the dishwasher. A single 70°C cycle can start tiny cracks and warping that shorten the life of both board and blades.
Step 3: Dry standing upright
After rinsing, pat the board dry with a tea towel and stand it on its edge so air can circulate on both faces. Leaving it flat on a wet worktop encourages uneven moisture, which leads to warping. A board that rocks or cups forces your knife edge into uneven contact with the surface, dulling it faster.
Weekly and monthly care for long lasting protection
In a busy kitchen, your board will see hundreds of knife strokes every week. A small amount of regular care keeps the surface smooth and kind to your knives.
Once a week: quick deep clean
For most home cooks, a weekly deep clean is enough:
- Sprinkle coarse salt lightly over the board.
- Cut a lemon in half and use the cut side to scrub the salt into the surface.
- Leave for 3 to 5 minutes, then rinse with warm water and dry upright.
This removes odours and surface stains without harsh chemicals that could dry the wood and make it more abrasive on your knife edge.
Every 4 to 8 weeks: oil your board
Oiling is the single most important step if you want your wooden cutting board to protect your knives for 5 to 10 years. An unoiled board absorbs water, swells and dries out again, which creates a rough surface and raised grain that drags on the blade.
How to oil your board:
- Use food safe mineral oil or a dedicated board oil. Avoid olive, sunflower or other cooking oils as they can go sticky and rancid.
- Make sure the board is completely dry before you begin.
- Pour a teaspoon of oil in the centre of one face.
- Spread it with a lint free cloth in small circles until the whole side is covered, including the edges.
- Let it soak in for at least 20 to 30 minutes, or overnight if the board is very dry.
- Wipe away any excess with a clean cloth so the surface is smooth, not greasy.
Repeat on the other side. For a new board, you might oil it once a week for the first month, then reduce to once a month.
Choosing the right wooden board for your knives
Not all wooden boards behave the same way under a knife. Grain, hardness and thickness all affect how well your knives are protected.
- Bamboo is light, stable and naturally moisture resistant. Moso bamboo, used in Deer & Oak boards, gives a smooth cutting surface that is kind to most home knives.
- Carbonised bamboo is heat treated for a deeper colour and slightly denser feel, which suits heavier chef’s knives.
- Acacia is a hardwood with attractive grain and a slightly softer feel under the blade, ideal if you use higher end Japanese or very thin edged knives.

Product problem guide: match your board to your knives
-
Problem: Knives feel dull after only a few weeks on your current board.
Solution: Switch from glass or plastic to a pre oiled wooden board. The Deer & Oak Carbonised Bamboo Board at 45x35cm gives a stable, slightly forgiving surface that reduces edge roll. -
Problem: You want to keep one knife set for raw meat and another for ready to eat foods.
Solution: Use a two board system. The Bamboo Double Pack provides a large 45x35cm board and a 38x28cm board so you can assign each to a knife set. -
Problem: You have invested in thinner, higher carbon steel knives and want a slightly softer landing for the edge.
Solution: Choose acacia. The Deer & Oak Acacia range offers a gentle cutting surface that is kind to fine edges while still being firm and stable. -
Problem: Your current board warps or slides, which feels unsafe and rough on the blade.
Solution: Move to a thicker, heavier board such as the Large Acacia Board at 2.1 kg, and always use a damp cloth or non slip mat underneath.
Who this is for
Ideal for:
- Home cooks in the UK or abroad who use their kitchen 3 to 7 days a week and want their knives to stay sharp for longer without constant sharpening.
- People who are happy to spend 2 to 3 minutes after each meal on basic board care and 10 to 15 minutes once a month on oiling.
- Anyone upgrading from glass, marble or thin plastic boards and looking for a stable, knife friendly surface with a natural look.
Not recommended for:
- Those who want totally maintenance free boards that can go in a 70°C dishwasher cycle every day.
- Commercial kitchens that must sanitise boards at very high temperatures several times a day.
- People who regularly chop through bones with cleavers, which is better suited to a specialist butcher’s block such as the Deer & Oak Premium Butcher’s Block.
FAQ
Q: How often should I oil my wooden chopping board to protect my knives?
A: For most home kitchens, oiling every 4 to 8 weeks is enough. If the board looks pale, feels rough or absorbs water quickly, oil it sooner. New boards may benefit from weekly oiling in the first month to build up a good protective layer.
Q: What is the best wood for a cutting board that is gentle on knives?
A: Medium hardness woods such as bamboo and acacia are ideal for most home knives. They are firm enough for safe chopping but not so hard that they chip the edge. Deer & Oak uses Moso bamboo and acacia, both of which balance durability with knife friendliness.
Q: Can I use both sides of my wooden kitchen boards?
A: Yes, you can and you should. Using both sides spreads out the knife marks and keeps the surface flatter for longer. Many people assign one side to raw meat and fish and the other to fruit, vegetables and bread to keep things simple and hygienic.
Q: Why should I avoid the dishwasher for wooden chopping boards?
A: Dishwashers combine high heat, strong detergents and long soaking times, which can cause wooden boards to crack, warp and dry out. Once the surface is damaged, it becomes rougher and less kind to knife edges. Hand washing in warm water keeps the board stable and smooth.
