If you choose the right bamboo and keep it oiled, bamboo cutting boards will not seriously damage your knives. On a hardness scale, quality Moso bamboo sits around 1,380 Janka, which is kinder to edges than glass or ceramic and similar to many hardwood boards, so with normal home cooking your knives should stay sharp for 6 to 8 weeks between honings.
Can bamboo cutting boards damage knives in everyday use?
The short answer is yes, bamboo can damage knives if it is very dry, very cheap or badly finished. However, a well made Moso bamboo board that is pre oiled and sanded smooth is classed as a medium cutting surface. In real terms that means:
- Stainless chef's knives usually keep a working edge for 6 to 8 weeks of home use
- High carbon Japanese style knives may need a light hone every 3 to 4 weeks
- You avoid the micro chipping that glass, stone or ceramic boards often cause within a few uses
So if you are choosing between plastic, glass and bamboo, properly finished Moso bamboo is kinder to your knives than glass and ceramic, and similar to quality hardwood, while still being an eco friendly option.
Why bamboo feels harder than other boards
Many people worry the first time they cut on bamboo because it feels firm under the knife. That is partly true. Bamboo is a grass with a high silica content, which is why very cheap boards can feel almost gritty. It is also laminated into strips, which makes the surface quite uniform and stable.
However, not all bamboo is equal. At Deer & Oak we use Moso bamboo because it offers a balance between durability and knife friendliness:
- Moso bamboo hardness: roughly 1,350 to 1,400 Janka
- Typical acacia wood: roughly 1,100 to 1,200 Janka
- Glass or ceramic: effectively many times harder than any knife steel
This is why you might notice a slightly quicker dulling on bamboo than on a very soft end grain board, but nowhere near the damage caused by glass or granite. The key is to combine the right bamboo with the right finish and maintenance.
How to stop bamboo cutting boards from dulling your knives
If you want bamboo that treats your knives kindly, there are four simple rules to follow:
-
Choose Moso bamboo
Look for boards that clearly state Moso bamboo on the specification. The Deer & Oak Bamboo Double Pack uses Moso for consistent density and fewer hard spots that can nick a fine edge. -
Pick the right thickness and size
A board that is too thin can flex and bounce, which is tiring for you and your knives. Our Large Bamboo Board at 45x35cm and 1.8kg gives a stable surface so the blade meets the board cleanly instead of chattering. -
Keep it oiled
A dry bamboo board feels harsher and can act like very fine sandpaper. A light coat of food safe mineral oil every 4 to 6 weeks fills the pores and softens the feel under the knife. You will often notice your knife gliding more easily after oiling. -
Use the right cutting technique
Let the blade do the work. Avoid heavy chopping straight down from height, which drives the edge into the board. A gentle rocking or slicing action is kinder to both board and knife, especially with thinner Japanese blades.
When to choose bamboo vs acacia or a butcher's block
Bamboo is not the only option if you care about your knives. Many cooks like to mix surfaces depending on what they are doing.
- Bamboo boards such as the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg) are ideal for vegetables, fruit, herbs and bread. They are eco friendly, lighter to move and easy to clean.
- Acacia boards such as our Large Acacia Board (45x35cm, 2.1kg) feel slightly softer under the knife and are a good match if you mostly use very fine Japanese blades or carbon steel knives.
- Heavy butcher's blocks like the Deer & Oak Premium Butcher's Block are thicker and absorb more impact, which is helpful for daily meat prep and heavier cleaver work.
If you want a single eco friendly board that will not punish your knives, a properly finished Moso bamboo board is usually the best balance. If you are a keen knife enthusiast with very thin blades, you might pair bamboo with an acacia or end grain board for your most delicate work.

Eco friendly benefits of Moso bamboo
If you are trying to kit out a more eco friendly kitchen, Moso bamboo has some clear advantages:
- Fast growth: Moso bamboo can grow up to 50cm per day in the right conditions, so it is highly renewable compared with slow growing hardwoods.
- Efficient use of material: Boards are made from laminated strips, which reduces waste and gives a stable surface for cutting.
- Long service life: With simple care, a Moso bamboo board can give 5 to 10 years of regular home use before it needs replacing.
When you combine that with the fact that a good bamboo board will not ruin your knives, it becomes a very practical eco friendly choice for everyday chopping.
Who this is for

Not recommended for...

FAQ
Q: Will a Moso bamboo cutting board ruin my expensive chef's knife?
A: No, a quality Moso bamboo board will not ruin a good knife, but it may dull the edge slightly faster than a very soft end grain board. With normal home cooking you can expect to hone every few weeks and sharpen a few times per year, which is acceptable for most stainless steel chef's knives.
Q: Is carbonised bamboo harsher on knife edges than natural bamboo?
A: Carbonised bamboo is heat treated for a darker colour, which can make it a touch harder and less forgiving than natural Moso bamboo. We suggest using a carbonised board such as the Deer & Oak Carbonised Bamboo Board mainly for serving and lighter prep, and keeping your main chopping on a natural Moso board.
Q: How often should I oil a bamboo cutting board to protect my knives?
A: For most British kitchens, oiling every 4 to 6 weeks is enough to keep a bamboo board conditioned. If the surface looks dry or feels rough, add a thin coat of food safe mineral oil, leave it to soak in for at least 20 minutes and wipe off the excess before using it again.
Q: Should I use separate bamboo boards for meat and vegetables?
A: Yes, it is safer and more practical to keep raw meat and ready to eat foods on different boards. A set like the Deer & Oak Bamboo Double Pack, with one 45x35cm board and one 38x28cm board, lets you dedicate one to meat and one to vegetables while giving both your knives and your food a cleaner environment.
Which Deer & Oak board should you choose?
If you want an eco friendly cutting surface that treats your knives kindly, the Deer & Oak Large Bamboo Board (45x35cm, 1.8kg, Moso bamboo, pre oiled) is the most balanced choice for everyday cooking. It is big enough for full Sunday roasts yet light enough to move and clean easily, and with simple care it will support your knives for 5 to 10 years.
If you prefer to separate meat and veg, the Bamboo Double Pack on Amazon UK gives you both the 45x35cm and 38x28cm boards in one set. If you lean towards a slightly softer feel under very fine blades, our acacia and butcher's block range is worth a look, including the Premium Butcher's Block for heavier prep.
