There's something different about living with wood. You notice it when you set down a tray made of Koa, or slice fruit on a board with that silky grain. It doesn't feel like glass or steel. It doesn't feel disposable. It feels alive.
At Martin & MacArthur, we've always leaned into that feeling. For us, Koa is not just another material. It's part of Hawaii's story, and part of the everyday beauty that can live in your home. We believe wood should be treated with care and used with respect.
And that's why a simple question matters more than it first seems: Is koa wood safe for serving food? Because it's not only about looks. It's about safety, trust, and honoring a tree that's been here for generations.
What makes Koa unique? What does "food safe" actually mean? And how does our craft ensure that every piece is beautiful and dependable at your table? Let’s break it down, below.
What Makes Koa Wood Unique?
Koa grows only in Hawaii and nowhere else on earth. This rarity alone makes it special. The trees rise from volcanic slopes, rooted in island soil, each grain telling the story of the land.
The look of Koa is unforgettable. Some boards glow golden, others sink into chocolate browns. Light might reveal fiery streaks or a curly shimmer, almost like the wood is alive. No two pieces ever match, so Koa has always been prized as treasure, not just timber.
Its role in Hawaiian culture runs deep. Ancient Hawaiians built canoes, carved weapons, and passed down heirlooms from Koa. The name means "warrior," a symbol of strength that still holds true today.
Now, Koa has a modern place too. Cutting boards. Serving trays. Everyday pieces that carry beauty and function together. When food rests on Koa, it's more than utility, it's tradition at the table.
Understanding "Food Safe": What It Really Means
That term "food safe" sounds technical, yet it speaks so much of trust. Are there any materials in the form of trays or boards that necessitate words against fouling, provided points might leach, provided toxics, splinter, or break down too fast? That is pretty much the core.
The finish is just as important as the wood itself. A coat of food-safe oil or wax keeps koa smooth, sealed, and long-lasting. Without it, even safe wood can wear down quickly. Like maple, walnut, or acacia, Koa is dense and reliable; durable enough for daily use, yet gentle on knives and resistant to bacteria.
The catch here is that “natural” is not always equally safe. Some woods carry tannins or oils that change taste, while others are too porous and soak up liquid. That's why finishing makes the difference. Sanding creates a silky surface. Food-safe oil seals it tight. Together, they transform Koa into a beautiful and trustworthy one for serving food.
Natural Safety of Untreated Koa
Untreated Koa on its own is considered safe. Science and tradition both point to the same conclusion: Koa is non-toxic and food-friendly. For generations in Hawaii, it has been shaped into bowls, utensils, and serving vessels. Families trusted it, not just for beauty, but for daily use.
Unlike some tropical woods, Koa doesn't contain heavy oils or tannins that irritate skin or alter the taste of food. It's mild in character and widely tolerated, even when left unfinished. That gives it an advantage over species known to leave strong flavors behind.
Of course, any raw wood still carries a degree of risk. Its natural pores can absorb moisture if left exposed. Over time, that creates room for bacteria to settle. The wood itself isn't harmful, but untreated surfaces don't offer the same protection modern kitchens expect.
This is why thoughtful finishing matters. Koa starts out safe, but with care and the right oils, it becomes lasting, durable, and ready for everyday serving.
Martin & MacArthur's Assurance: Safe Finishes & Craftsmanship
Each Martin & MacArthur serving board is finished with a resilient lacquer that is food safe. This special finish brings out the rich glow of Koa without ever compromising safety. Serving boards should never be used for cutting foods with a knife because the lacquer finish could be damaged.
On the other hand, Martin & MacArthur cutting boards are finished with bees oil which is totally food safe. Be sure you know which type of Martin & MacArthur board you need, a serving board or a cutting board.
Careful Sanding to a Smooth, Splinter-Free Surface
The process begins with hand sanding. Each piece is worked until the surface feels silky smooth without any rough sports and splinters. It all just has the natural touch of Koa that is safe for your table.
Application of Non-Toxic Finishes
After the sand process is done, wood gets sealed with all sorts of safe oils, and these protective layers ensure to shield the grain from moisture and stains while enhancing the natural beauty. Chosen ones are always the non-toxic finishes, and anything that can leach into food gets into declination.
Inspection for Quality and Durability
Every product passes through inspection before it leaves the workshop. Craftsmen check for smoothness, finish, and strength. This ensures each board or tray is ready for daily use, not just display.
Best-Practice Care Tips for Long-Term Safety & Beauty
Wash by Hand Gently; Never Soak
Give Koa a loving touch. Using mild soap and cool water would suffice for cleaning a board/tray by hand. Never let it soak. When the water stands for a long time, it may loosen the internal fibers or cause swellings and cracks in Koa. Rinse it briefly instead of soaking.
Dry Thoroughly
Dry right after washing. Wipe the surface with a sheer cloth to remove moisture and set aside for complete air drying. Even the last traces of water left on its surface can lessen Koa's lifespan.
Oil Once a Week or Month, Depending on Use with Food-Safe Oil
Keep Koa happy by layering oil all over it. A light coating of mineral oil or a mixture of beeswax will give the surface a shine and seal the essence. Heavy usage asks for weekly oiling; light use requires once a month.
Keep in a Room Temperature, Low-Humidity Environment
Koa enjoys being in the center. It needs to be kept in a cool and dry environment, away from direct sunlight, wet corners, or any kind of dampness. Excessive heating or humidity spells bad for color and stresses the wood.
Avoid Using the Dishwasher, Harsh Soaps, or Scrubbing Pads
Dishwashers are too harsh for Koa. The chlorinated water and heat seep away the oils and wipe the surface. Soap powder acts as a scouring agent and scratches the wood, leaving it exposed. Gentle cleaning will ensure lasting beauty.
Proper care is not difficult. A few simple habits will keep koa food-safe and its character preserved for many years.
Celebrating Craft & Sustainability
Responsible Sourcing
Martin & MacArthur never cut corners when it comes to Koa. Every piece of wood comes from fallen trees or responsibly harvested sources without shortcuts and exploitation. This commitment ensures that Hawaii's precious koa forests are respected and preserved for the future.
Reforestation Efforts
Sustainability doesn't stop at sourcing. Reforestation programs actively restore Koa to Hawaii's landscapes. By planting young trees, Martin & MacArthur help strengthen native ecosystems and protect habitats unique to the islands. It's an investment in the land that gives so much.
Skilled Woodworking
Each serving board or tray is more than a product, it's a display of craftsmanship. Artisans shape, sand, and finish every curve by hand. The process blends traditional techniques with modern precision, creating functional and deeply personal pieces.
Cultural Respect
Koa has always held meaning in Hawaiian culture. Using it requires care and reverence. Every creation honors that heritage, turning everyday items into objects that carry a story. The wood becomes not just useful, but symbolic.
An Art Form That Honors the Land
Crafting with Koa goes beyond utility. Each piece reflects a philosophy: to use what nature provides responsibly and create lasting beauty. Koa serving ware is more than just a usefully functional object; it is an opportunity to hold a piece of Hawaii's history in one's hands.
Time To Wrap!
Koa wood is truly a beautiful sum of beauty and utility. Untreated, it is naturally safe; with Martin & MacArthur's hand-applied finishing, every single board and tray is rendered completely food-serviceable. The procedure is deliberate, careful, and based on trust.
Care stops not even at the workshop. Gentle washing, occasional oiling, and thoughtful storage ensure that your Koa serving ware remains handsome and safe for years. It is a collaboration of nature, craftsmanship, and yourself.
