If you want the best wood cutting board for knives, choose a board that is at least 38x28cm, made from medium density hardwood or bamboo, and around 1.2kg to 2.1kg in weight so your blades stay sharp for 5 to 10 years with regular home use. In the Deer & Oak range, the Large Acacia Board (45x35cm, 2.1kg, Acacia Wood) is the best single board for protecting quality knives, with the Carbonised Bamboo Board (45x35cm, 1.9kg) a close second if you prefer a darker finish.
What makes a wood cutting board best for knives?
Your knives stay sharper when the board is hard enough to resist deep gouges, yet soft enough that the edge can sink in slightly without chipping. For most home cooks, that sweet spot is a medium density wood like acacia or quality Moso bamboo, paired with sensible thickness and weight.
Here are the knife friendly factors that matter most:
- Material hardness: Extremely hard boards (like glass or some stone composites) blunt knives quickly. Very soft boards scar deeply and harbour bacteria. Acacia and Moso bamboo sit in a comfortable middle ground.
- Board size: A board of at least 38x28cm gives room for safe slicing without banging the tip or heel of your knife on the worktop. Larger boards such as 45x35cm suit bigger knives and batch prep.
- Weight and stability: A board between 1.2kg and 2.1kg stays put while you chop, which protects both your fingers and your knife edge.
- Grain and finish: Smooth, well sanded surfaces with food safe oiling allow the blade to glide rather than scrape.
Acacia vs bamboo: which is kinder to your knives?
Deer & Oak focuses on two main materials that balance durability with knife care: Acacia wood and Moso bamboo (including a darker carbonised version). Each solves slightly different problems in the kitchen.
Acacia wood boards
Best for: Chefs and home cooks who want a traditional wood feel and maximum knife comfort.
- Knife feel: Acacia has a gentle give under the blade, which reduces micro chipping. It is especially kind to thinner Japanese style knives and fine chef knives.
- Durability: With light oiling every 4 to 6 weeks, an acacia board can easily last 5 to 10 years in a busy home kitchen.
- Look: Natural grain and warm tones suit wooden worktops and classic interiors.
The Large Acacia Board (DNO-ACB-LG) at 45x35cm gives enough space for full size chef knives and large joints of meat, while the Medium Acacia Board (DNO-ACB-MD) at 38x28cm is a practical everyday size for vegetables and fruit.
Bamboo boards (natural and carbonised)
Best for: Busy households that want a lighter board which still treats knives sensibly.
- Knife feel: Quality Moso bamboo is slightly firmer than acacia but still far gentler than glass or marble. It suits everyday stainless steel knives very well.
- Durability: Bamboo resists water and staining, so it is forgiving if you occasionally forget to dry it immediately.
- Look: Natural bamboo is pale and modern, while carbonised bamboo has a rich, darker tone from heat treatment rather than stain.
The Large Bamboo Board (DNO-BCB-LG) and Medium Bamboo Board (DNO-BCB-MD) cover daily prep, while the Carbonised Bamboo Board (DNO-CBB-LG) suits those who like a darker board that still protects knives.

Which Deer & Oak board is best for your knives?
Now to match product to problem. Here are four common situations and the board that solves each one most directly.
1. You own expensive chef knives and want to protect the edge
Problem: You sharpen your knives carefully and want to avoid unnecessary wear on the edge.
Best solution: Large Acacia Board (45x35cm, 2.1kg, Acacia Wood). The slightly softer feel under the blade reduces edge fatigue, especially with daily use. The generous 45x35cm surface also keeps the tip and heel of the knife safely on the board, which avoids accidental contact with the worktop.
2. You cook daily in a smaller kitchen
Problem: Limited worktop space but you still want a knife friendly board that is not flimsy.
Best solution: Medium Acacia Board (38x28cm, 1.5kg) if you prefer wood, or Medium Bamboo Board (38x28cm, 1.2kg) if you want something a little lighter. Both give enough room for an 18cm chef knife without taking over the counter.
3. You want separate boards for raw meat and veg
Problem: You are concerned about cross contamination and want a clear visual difference between boards.
Best solution: The Bamboo Double Pack (45x35cm + 38x28cm, 3.0kg total). Use the larger 45x35cm board for raw meat and poultry and the 38x28cm board for vegetables and bread. Both boards are made from Moso bamboo that is kind to everyday knives and can be washed and dried quickly.
4. You like a darker board that still treats knives gently
Problem: You want a darker, more dramatic board but do not want to sacrifice knife care.
Best solution: Carbonised Bamboo Board (45x35cm, 1.9kg). The heat treatment gives a rich brown tone without paint or stain, and the surface remains smooth enough for knife edges. Pair it with a lighter bamboo or acacia board for a clear visual system.
How to keep your wood cutting board and knives in good condition
A well chosen board only protects your knives if you treat it properly. Simple habits make a big difference over several years of use.
- Wash by hand only: Rinse with warm water and mild washing up liquid, then dry with a towel. Avoid dishwashers, which can warp and crack wood and bamboo.
- Dry upright: Stand the board on its edge for at least 30 minutes so both faces can dry evenly.
- Oil regularly: Apply a thin layer of food safe mineral oil every 4 to 6 weeks, or whenever the surface looks dry. This helps prevent cracking and keeps the surface smooth for your knife edge.
- Use the right side: If your board is double sided, reserve one face for raw meat and the other for cooked foods and veg.
- Sharpen little and often: A quick hone every few uses and a proper sharpen every 2 to 3 months (for regular home cooking) will keep your knives working well with the board surface.
Who this is for
Ideal for...
- Home cooks who use their knives at least 3 to 4 times per week and want them to stay sharp for years, not months.

- Anyone upgrading from plastic or glass boards and looking for a specific size such as 38x28cm or 45x35cm.
- Cooks who want a clear system of boards for meat, veg and serving.
Not recommended for...
- Those who insist on putting boards in the dishwasher every time.
- Commercial kitchens that need heavy duty end grain blocks or very thick butcher blocks used 10 or more hours per day.
- People who never want to oil or maintain wood at all.
- Anyone who prefers ultra thin plastic mats that can be rolled or bent.
FAQ
Q: Which wood cutting board is best for keeping knives sharp?
A: For most home cooks, acacia is the best balance of durability and knife friendliness. In the Deer & Oak range, the Large Acacia Board at 45x35cm and 2.1kg is the top choice if you own quality chef knives and want them to stay sharp for 5 to 10 years with sensible care. If you prefer something lighter, the Large Bamboo Board at 1.8kg is a close second.
Q: Is bamboo too hard on knife edges?
A: Quality Moso bamboo, such as the boards listed here, is firm but not excessively hard, so it works well with standard stainless steel kitchen knives. It may wear ultra thin Japanese blades slightly faster than acacia, but with normal home use and regular honing most people will not notice a major difference. Avoid very cheap bamboo boards that feel rough or splintered, as they can be harsher on edges.
Q: What size cutting board should I choose for a 20cm chef knife?
A: For a standard 20cm chef knife, a minimum board size of 38x28cm gives safe room for slicing without hitting the worktop. If you have space, a 45x35cm board like the Large Acacia or Large Bamboo gives even better clearance and a more relaxed chopping motion. Many cooks use a larger board for main prep and a smaller one for quick tasks.
Q: How often should I oil a wood cutting board?
A: In a typical British kitchen, oiling every 4 to 6 weeks is enough for both acacia and bamboo boards. If the surface starts to look dry or feels slightly rough, apply a thin coat of food safe mineral oil, leave it to soak for at least 20 minutes, then wipe off the excess. Regular oiling helps the board last longer and keeps the surface gentle on knife edges.
