If you sharpen your kitchen knives every 3 to 6 months and use a quality board, Moso bamboo cutting boards will not dull knives more than plastic in normal home use. In fact, a well finished bamboo board can keep an edge comfortably for 4 to 8 weeks of daily cooking before you notice any drop in sharpness, which is very similar to a good quality plastic board.
Can bamboo cutting boards dull knives more than plastic?
The short answer is no, not if you choose the right bamboo and use it properly. Cheap bamboo boards can contain hard glue lines and gritty fibres that blunt a fine edge faster than softer woods or premium plastics. High quality Moso bamboo, like the boards we use at Deer & Oak, is pressed and sanded so the surface hardness is controlled and kinder to your knives.
In practical terms, if you slice vegetables and boneless meat most days:
- On a good Moso bamboo board you might touch up your knife every 4 to 8 weeks
- On a decent plastic board you might touch up every 4 to 8 weeks as well
The difference is usually less about the material label and more about build quality, surface finish and how you treat the board.
Moso bamboo vs plastic: what actually touches your knife?
When you ask "can bamboo cutting boards dull knives more than plastic", you are really asking what the blade is hitting with every cut. Three main factors matter:
-
Surface hardness
High quality Moso bamboo has a Janka hardness of roughly 1,380 lbf, which is harder than many traditional woods but still forgiving enough for kitchen knives. Plastic boards feel softer, but they can develop deep grooves that catch and roll a fine edge. A smooth, oiled bamboo surface spreads the impact more evenly. -
Glue and grain direction
Cheap bamboo boards often use too much brittle glue, which can be harsher than the bamboo itself. Deer & Oak boards use food safe adhesive with tight joints, so the knife mostly meets bamboo fibres instead of hard glue lines. -
Surface condition
Dry, cracked or gritty boards of any material will chew up an edge. Regular oiling on bamboo and proper cleaning on plastic make a bigger difference to sharpness than the material alone.
If your priority is eco friendly kitchenware that still treats your knives kindly, Moso bamboo is a strong alternative to plastic. It is fast growing, needs no replanting and can last 5 to 10 years in a home kitchen with basic care.
Eco friendly cutting boards that respect your knives
Bamboo sits in a helpful middle ground between soft plastic and very hard surfaces like glass or stone. It is:
- More eco friendly than plastic because Moso bamboo is a rapidly renewable grass
- Gentler on knives than glass, marble or ceramic which can dull or chip a blade in a single session
- More stable than many cheap plastics that warp under heat or heavy use
Deer & Oak boards are pre oiled so you start with a smooth, sealed surface. That finish helps your knife glide rather than bite, which reduces micro chipping along the edge.
How to stop bamboo boards dulling your knives
Whatever board you choose, technique and care are what really protect your knives.
Use a gentle cutting action
- Use a slicing or rocking motion instead of straight down chopping
- Avoid twisting the blade against the board to scrape food
- Use the spine of the knife or a bench scraper to move chopped food
Keep the surface conditioned
- Oil bamboo every 3 to 4 weeks with food safe mineral oil
- Never soak bamboo or put it in the dishwasher
- Dry upright after washing so the board does not cup or crack
Match the board to the job
- Use a dedicated board for meat and one for fruit and vegetables
- Choose a larger board, such as 45x35cm, if you often prep family meals
- Keep a small plastic board for very messy tasks if you like, and use bamboo for your daily cutting

FAQ
Q: Do bamboo cutting boards actually dull knives faster than plastic?
A: With high quality Moso bamboo the dulling rate is very similar to a good plastic board in home use. Most people will notice their knives need a quick hone after 4 to 8 weeks of regular chopping on either surface. Cheap, very hard or poorly finished bamboo can be harsher, which is why build quality matters.
Q: How long will a Moso bamboo cutting board last if I use it daily?
A: With gentle hand washing and oiling every 3 to 4 weeks, a Moso bamboo board can last 5 to 10 years in a typical household. Deep resurfacing might only be needed once or twice in that time. Heavy cleaver work or dishwasher use will shorten its life considerably.
Q: Is carbonised bamboo worse for my knives than natural bamboo?
A: Carbonised bamboo is heated to create a darker colour, which can slightly change hardness, but in practice the effect on knife wear is minimal if the board is well made and well sanded. Our 45x35cm Carbonised Bamboo Board at 1.9 kg is finished to the same smooth standard as our natural Moso boards, so it remains knife friendly.
Q: Should I choose bamboo or acacia if I want the kindest surface for my knives?
A: Both are suitable for sharp kitchen knives when finished properly. Acacia, such as our 2.1 kg Large Acacia Board, feels a touch softer under the blade and can be slightly more forgiving, while Moso bamboo is lighter and more eco friendly. Many cooks keep one of each and use bamboo for most prep and acacia for carving and serving.
Which Deer & Oak board should you choose?
If you want an eco friendly board that will not dull your knives more than plastic, the Large Bamboo Board DNO-BCB-LG at 45x35cm and 1.8kg is the most practical starting point for a British kitchen. It gives you enough space for full meals, stays light enough to move easily and, with monthly oiling, supports a 3 to 6 month sharpening cycle for most cooks.
