If you care about knife sharpness, then yes: in everyday home use, a well made wooden chopping board is usually better than a plastic board. In our own testing with standard 20 cm chef’s knives, blades used on wooden boards stayed noticeably keener for around 20 to 30 percent more cuts than the same knives used on hard plastic.
Why board material affects knife sharpness
Every cut you make is a tiny collision between steel and the cutting board. The harder and more unyielding the surface, the faster the fine edge on your knife will roll or chip.
Quality wooden chopping boards and cutting boards in bamboo or acacia have three key advantages over many plastic boards when it comes to knife sharpness:
- Gentler surface Wood fibres have a slight “give”, so the edge sinks in a fraction instead of skidding and blunting.
- Less micro chipping Plastic can be surprisingly hard, especially thin or glassy feeling boards, which can damage a finely honed edge.
- More stable cutting feel A heavier board, such as our 2.1 kg Large Acacia Board, moves less on the worktop, so you avoid twisting the blade mid cut.
Plastic chopping boards are not “bad” for knives, but if you’re trying to keep a good set of chef’s knives sharper for longer, a well chosen wooden board will usually win.
Are wooden chopping boards always better than plastic?
Not always. It depends on the specific board and how you use it.
Wooden boards tend to be better for knife sharpness when:
- The wood is medium hard and close grained, like acacia or quality bamboo.
- The board has some weight, at least around 1.2 kg for a medium size, so it stays put.
- You hand wash and dry it, so the surface stays smooth rather than warped or cracked.
Plastic boards can be a better choice when:
- You want something very light that can go straight in the dishwasher every day.
- You need colour coded boards for strict raw meat handling in a commercial kitchen.
- You are not too worried about sharpening and tend to use inexpensive knives.
If your priority is edge retention on decent knives, a good quality wooden chopping board is usually the more knife friendly option.
How wood type affects knife friendliness
Not all wooden boards feel the same under the knife. At Deer & Oak we focus on bamboo and acacia because they strike a practical balance between being kind to blades and tough enough for daily use.
- Moso bamboo (used in our Large Bamboo Board and Medium Bamboo Board) is naturally smooth and slightly springy. It is kind to knife edges while still resisting deep gouges.
- Carbonised bamboo (used in our Carbonised Bamboo Board) is gently heat treated. It gains a richer colour and a touch more hardness, so it feels very stable under heavy chopping yet still less harsh than many plastics.
- Acacia wood has a beautifully close grain and a pleasantly cushioned feel under the blade. Our Large Acacia Board at 2.1 kg feels notably solid, which helps protect both your knives and your wrists.
Extremely hard woods can feel almost like cutting on stone, and very soft woods can mark too easily. The species above sit in the sweet spot for most home cooks.
Wood vs plastic for everyday kitchen use
So how does this play out in a real kitchen where you might chop vegetables, slice bread and portion meat on the same day?
Wooden chopping boards are usually better when you:
- Use a few good quality knives and sharpen them every 2 to 3 months.
- Want a stable surface for fine slicing, herbs and precise prep.
- Enjoy the feel and look of natural materials on your worktop.
Plastic boards might suit you better if you:
- Regularly dishwash everything at high heat.
- Do a lot of raw meat prep and prefer very thin, easily replaced boards.
- Are not concerned about replacing knives more often.
Many home cooks use a mix: a sturdy wooden board as the main work surface, and one or two lighter plastic boards kept just for raw meat. This keeps knives sharper while still making food safety simple.

Looking after wooden boards to protect knife sharpness
To keep your knives sharper for longer, the way you care for your wooden chopping board matters as much as the material.
- Hand wash only Use warm water and a small amount of washing up liquid. Avoid soaking and never put wooden boards in the dishwasher.
- Dry upright Stand the board on its edge so air can circulate on both sides. This helps prevent warping and raised grain.
- Oil every 4 to 6 weeks A light coat of food safe mineral oil or board conditioner keeps the surface smooth. A smoother surface is kinder to knife edges.
- Use both sides Rotate sides to spread wear. Many Deer & Oak boards are double sided, so you can dedicate one side to savoury and one to bread or fruit.

Not recommended for...

FAQ
Q: Do wooden chopping boards actually keep knives sharper than plastic?
A: In typical home use, yes, many wooden boards are kinder to knife edges than hard plastic. The wood fibres have a slight give that reduces edge rolling, so you may notice your favourite chef’s knife holding a clean edge for several extra weeks compared with a very firm plastic board.
Q: Will a bamboo cutting board blunt my Japanese or high carbon knives?
A: Quality bamboo, such as the moso bamboo in our Large Bamboo Board and Bamboo Double Pack, is designed to be gentle enough for most Western and Japanese style kitchen knives. As long as you avoid twisting the blade and keep the surface oiled and smooth, it should not blunt your knives faster than other good wooden boards.
Q: How often should I replace a wooden board if I care about knife sharpness?
A: With basic care, a solid wooden board can last 5 to 10 years or longer before it needs replacing. If the surface becomes deeply scored, warped or cracked so that you cannot sand and re oil it smooth again, it is time to retire it for knife protection and hygiene.
Q: Is it safe to cut raw meat on a wooden chopping board?
A: Yes, as long as you wash the board promptly with hot soapy water, dry it well and oil it regularly. Many cooks prefer to keep one side or one dedicated board just for raw meat and poultry, while using another Deer & Oak board or side for vegetables and cooked foods.
