If you choose the right board, bamboo cutting boards will not noticeably dull your knives faster than other wooden boards. High quality moso bamboo boards with a smooth finish, like a 45x35cm Deer & Oak board, typically keep everyday kitchen knives sharp for 3 to 6 months of regular home use before needing a standard touch up on a honing steel.
Do bamboo cutting boards actually dull knives?
The honest answer is: it depends on the quality of the bamboo and how you use your knives.
Bamboo is naturally harder than many traditional timbers. On the Janka hardness scale, typical bamboo sits around 1,380, while maple is roughly 1,450 and acacia can be 1,500 or more. That extra firmness is why people worry about knife dulling.
In practice, a well made, eco-friendly moso bamboo board with rounded edges and a finely sanded surface will treat your knives kindly. What really harms an edge is cutting on glass, ceramic or directly on worktops, or scraping the blade sideways. Compared with those, a bamboo board is far gentler and gives a predictable cutting surface.
Moso bamboo vs other materials for knife care
Not all bamboo is equal. Deer & Oak boards use moso bamboo, which grows to full height in around 5 years and is harvested without harming the root system, so it regrows. That makes it a genuinely eco-friendly choice compared with slow growing hardwoods.
Here is how moso bamboo compares with other common board materials for knife wear:
- Moso bamboo: Firm, light, naturally antibacterial. Slightly harder on an edge than softwoods, but kinder than glass or stone. Ideal if you keep knives reasonably sharp and use a normal slicing motion.
- Carbonised bamboo: Heat treated for a darker colour. Very similar hardness to natural bamboo, so knife wear is comparable, while giving a richer look on the worktop.
- Acacia wood: A touch heavier and denser than bamboo. Feels a bit softer under the knife, so it is very forgiving for fine edges on premium chef knives.
- Glass / stone: Extremely hard surfaces that can blunt a knife edge in a single session of prep. Not recommended for any quality knife.
- Plastic: Softer on the edge but can develop deep grooves that harbour bacteria. Often used for raw meat but many cooks prefer wood or bamboo for daily prep.
If your main question is "what is the best eco-friendly board that will not quickly dull my knives?", a medium or large moso bamboo board is a strong answer, with acacia as a slightly softer alternative for very fine blades.
How to use bamboo cutting boards without dulling your knives
How you cut has as much impact on knife sharpness as what you cut on. To keep your knives happy on bamboo:
- Use a slicing motion rather than chopping straight down with force. Let the edge glide.
- Avoid twisting the blade in the board. Lift and reset instead of prising food sideways.
- Scrape with the spine of the knife, not the cutting edge, when moving chopped food.
- Hone regularly. A few strokes on a honing steel every 2 to 3 uses will keep the edge aligned.
- Keep the surface conditioned. A lightly oiled bamboo surface has a touch more “give” and is friendlier to the edge.
Used this way, most home cooks find they only need a proper sharpen every few months, whether they choose bamboo or acacia.

Eco-friendly care that protects your knives
Good care keeps both your board and your knives working well for 5 to 10 years. Bamboo responds best to simple, regular maintenance.
- Wash by hand with warm water and a small amount of washing up liquid. Rinse quickly and dry with a tea towel.
- Never soak in the sink or put in the dishwasher. Prolonged water and heat can warp the board and create a harsher surface.
- Oil every 4 to 6 weeks with a food safe mineral oil or board conditioner to keep the surface sealed and slightly supple.
- Use both sides to keep wear even. Many cooks reserve one side for meat and the other for vegetables.
Looked after this way, a Deer & Oak bamboo board will stay smooth and kind to your knives, while giving you an eco-friendly surface made from fast growing moso bamboo rather than slow grown hardwoods.

FAQ
Q: Can bamboo cutting boards dull knives faster than acacia?
A: In most home kitchens, the difference is small. Acacia is slightly denser but often feels a bit softer under the blade, so it can be a touch gentler on very fine edges. For standard Western style knives used daily, a moso bamboo board will give similar sharpening intervals if you hone regularly.
Q: How long will a moso bamboo board last before it affects my knives?
A: With basic care, a quality moso bamboo board can last 5 to 10 years. As long as you keep it oiled and avoid deep cuts or cracks, the surface stays smooth and does not become noticeably harsher on your knife edge over time.
Q: Is carbonised bamboo worse for knife sharpness than natural bamboo?
A: Carbonised bamboo is heat treated mainly for colour, not extra hardness, so knife wear is very similar to natural bamboo. The key is the finish: a well sanded, pre oiled carbonised board will be just as friendly to your knives as a natural moso bamboo board.
Q: Should I choose bamboo or acacia if I have expensive chef knives?
A: If you own high end, thin edged chef knives and want maximum protection, acacia gives a slightly softer feel that many enthusiasts prefer. If you want a lighter, eco-friendly option that is still kind to a good set of knives, a moso bamboo board is a sensible and practical choice.
Which Deer & Oak board should you choose?
If you want an eco-friendly board that will not quickly dull your knives, the Large Bamboo Board 45x35 cm (1.8 kg, moso bamboo, £34.99) is a very balanced option for most British kitchens. It is big enough for Sunday roasts, light enough to move easily, and kind to a typical set of stainless steel knives when you hone them regularly.
If you would like separate boards for meat and vegetables, the Bamboo Double Pack pairs a 45x35 cm and a 38x28 cm moso bamboo board at 3.0 kg for the set, giving you two eco-friendly surfaces without taking over your worktop.
Cooks with finer edged knives who prefer a slightly softer feel under the blade may favour our acacia range instead. The Large Acacia Board 45x35 cm (2.1 kg, £44.99) offers a weightier, richly grained surface that many knife enthusiasts enjoy.
