Bamboo cutting boards are everywhere because they are cheap, light, and marketed as the eco-friendly choice. Hardwood boards cost more and weigh more, and their fans say they are far better for your knives. Both camps are partly right.
The short version is that bamboo is not wood at all. It is a grass, and a bamboo board is made of many thin strips glued together. That makes it hard, dense, and slow to stain, and it also makes it harder on a knife edge than a good maple or walnut board.
This guide covers what the material data actually says, where bamboo genuinely wins, where hardwood does, and how to tell a good board of either kind from a poor one.
| Bamboo | Maple or walnut | Rubberwood | |
|---|---|---|---|
| What it is | A grass, laminated from strips | Solid hardwood | Hardwood from latex plantations |
| Janka hardness (lbf) | 1,410 to 1,610 | 1,450 (hard maple), 1,010 (black walnut) | 960 |
| On your knife edge | Hardest on edges | Gentle | Gentle |
| Weight | Light | Heavy | Medium |
| Can be sanded and refinished | Lightly | Yes, repeatedly | Yes |
| Dishwasher | No | No | No |
What the Material Data Says
The numbers below come from The Wood Database, which is the standard free reference for wood properties.
Bamboo is a grass
Bamboo belongs to the grass family, Poaceae, and grows to full height within about a year. That fast growth is the root of its sustainability reputation. A bamboo stalk is hollow and thin-walled, so a board has to be built by slicing it into strips and laminating them with adhesive. The quality of that adhesive and gluing is a big part of what separates a good bamboo board from a cheap one.
Bamboo is hard, and it contains silica
The Wood Database gives bamboo a Janka hardness of 1,410 to 1,610 lbf, as hard as or harder than hard maple at 1,450. It also notes that bamboo is high in silica, from 0.5 to 4.0 percent, concentrated in the outer layers of the stem. Woodworkers are advised to use carbide tools on it for that reason. Hardness plus silica is why a bamboo board wears a knife edge down faster than a hardwood board of similar hardness.
Hardwoods give a little
Maple, walnut, and cherry have a fine, even grain that yields slightly under the knife. Black walnut, at 1,010 lbf, is noticeably softer than bamboo. That small give is exactly what keeps an edge sharp for longer, and it is why knife enthusiasts tend to avoid bamboo.
Where rubberwood fits
Rubberwood comes from Hevea brasiliensis, the tree tapped for natural latex. The Wood Database notes that rubberwood lumber is typically harvested from plantations at the end of the trees' productive life, often after about thirty years, and lists its hardness at 960 lbf. It is a common, affordable choice for kitchen woodenware and is what the ROO Cutting Board is made from.
What to Look for in a Bamboo or Wood Cutting Board
Whichever material you pick, these are the checks that separate a board that lasts from one that splits in a year.
Construction and glue lines
On bamboo, look for tight, even strips with no gaps, and a maker that states the adhesive is food safe. Cheap bamboo boards are the ones most likely to separate along a glue line after a few months of washing. On hardwood, check that the seams between strips are flush and tight.
Knife friendliness
If you own good knives, hardwood is the better surface. If your knives are inexpensive and you sharpen them regularly anyway, bamboo is a reasonable trade for a lighter, cheaper board.
Thickness and weight
Bamboo boards are usually thinner and lighter, which is great for storage and washing and less great for stability, because a light board slides. Hardwood boards around an inch thick resist warping and stay put better through sheer weight.
Surface finish
Both should be finished with food-safe mineral oil or a board cream, not a varnish. A bamboo board that feels waxy or plastic-coated has probably been lacquered, and that coating will chip under a knife.
Care you will actually do
Neither material goes in the dishwasher. Both need hand washing, drying on edge, and occasional oiling. Bamboo tends to absorb less water and stain less, which makes it a little more forgiving if you are not diligent.
Size for your space
A 12 by 18 inch board is roomy but needs a real sink to wash it in. For small kitchens, a board around 14 by 10 inches handles most prep and stores upright in a cabinet.

Which Board to Choose
Four sensible options, matched to the way people actually cook.
Solid bamboo board
A well-made bamboo board is inexpensive, light enough to carry to the sink with one hand, and slow to stain. It is a good first board, a good second board for fruit and bread, and a sensible choice for anyone who values low weight over knife care. Just expect to sharpen a little more often.
Look for
- Tight strips with no visible gaps
- A stated food-safe adhesive
- An oiled, not lacquered, surface
Watch out for
- Harder on knife edges than hardwood
- Budget boards can split along glue lines
- Light boards slide on smooth counters
Edge grain maple or walnut
The classic hardwood board. Maple is the traditional choice, pale and tight-grained, and walnut is softer on an edge and darker, so it hides stains. Both can be sanded back and re-oiled for years, which means one good board can outlast several bamboo ones.
Look for
- Around an inch thick
- Closed, even grain
- Flush seams and rounded edges
Watch out for
- Heavier and pricier than bamboo
- Needs regular oiling
Upgrade Your Prep: Get the ROO Bundle
ROO is a silicone mat that sits under your cutting board. It grips smooth countertops so the board never slides, and its built-in 7-cup pouch catches peels and trimmings as you cut. The Bundle includes the mat, a rubberwood board, and a reusable storage bag. $54.99.
Shop the ROO Bundle →Rubberwood board
Rubberwood sits between bamboo and premium hardwood. It is softer than bamboo, so it is kinder to your knives, it is usually more affordable than maple or walnut, and it comes from trees that have already served their purpose on a latex plantation. The ROO Cutting Board, 13.75 by 9.75 by 0.8 inches, is rubberwood and is sold alone or in the ROO Bundle.
Look for
- Even color and tight seams
- An oiled finish
- A size that suits your counter
Watch out for
- Little natural resistance to rot, so dry it fully
- People with latex allergies may want a different wood
End grain hardwood block
If you are weighing bamboo against wood because you want the best possible surface, end grain hardwood is the top of that ladder. It is the most forgiving surface for an edge and hides knife marks, at the cost of weight, price, and more frequent oiling.
Look for
- Thickness around 1.5 inches or more
- Tight joints across the pattern
Watch out for
- Heavy and expensive
- Cracks if soaked
Upgrade Your Prep Workflow: The ROO Bundle
Bamboo and compact wooden boards share one weakness: they are light, and a light board on a smooth countertop slides, especially once a little water or juice gets underneath. The ROO Mat sits under the board and grips smooth counters like granite, tile, and polished stone, so the board stays where you put it, and its built-in pouch catches up to 7 cups of peels and trimmings off the front edge. The ROO Bundle pairs the mat with a rubberwood board that fits it, for $54.99.

This guide is built from published material data, manufacturer care instructions, and the complaints that come up again and again in buyer reviews and cooking forums. It is not based on hands-on testing, and it does not rank brands, because a ranking without testing would be a guess. Hardness, silica, and sourcing figures come from The Wood Database, checked September 22, 2026. Where ROO fits the job we say so, and where it does not we say that too.

Frequently Asked Questions
Are bamboo cutting boards good?
Yes, for the price. They are light, slow to stain, and renewable. Their main drawback is that they are harder on knife edges than hardwoods like maple and walnut, and cheap ones can split along glue lines.
What are the disadvantages of a bamboo cutting board?
Faster knife dulling, because bamboo is hard and contains silica. Glue lines that can fail on budget boards. Light weight that makes the board slide. And limited refinishing, since the laminated surface cannot be sanded back as deeply as solid hardwood.
Is it safe to put raw meat on a bamboo cutting board?
It can be, provided you wash it promptly with hot soapy water and dry it fully. Many cooks still prefer a separate non-porous board for raw meat that can go through the dishwasher, and keep wood or bamboo for produce and cooked food.
Why don't more woodworkers use bamboo instead of wood?
Bamboo is a hollow grass, so it has to be sliced into strips and laminated before it can become a board, and its silica content wears down cutting tools. Solid hardwood is simpler to work and easier to refinish.
Can bamboo cutting boards go in the dishwasher?
No. Heat and long water exposure weaken the glue and can split the board. Wash by hand and dry standing on an edge.
Is rubberwood a good cutting board wood?
Yes. It is a genuine hardwood, softer than bamboo and kind to knife edges, and it is widely used for kitchen woodenware. The Wood Database notes it has little natural rot resistance, so dry it fully after washing, and that people with latex allergies may react to it.
Bamboo is a fair budget board with one real cost, which is your knife edge. Hardwood costs more and treats knives better, and it can be refinished for years. If you want something in between, rubberwood is gentle on knives without the premium price. Whichever you choose, give it a non-slip base so the lighter board stays put.
