Walnut and maple are the two most popular cutting board hardwoods in America, and we build with both. Here's the honest comparison.
Hardness
Hard maple runs about 1,450 on the Janka scale; black walnut about 1,010. Both are comfortably in the ideal cutting board range — hard enough to resist gouging, soft enough not to wreck an edge. Maple resists dents slightly better; walnut is slightly gentler on knives. Over years of daily use, walnut owners sharpen a little less; maple owners see a few less marks. It's a genuine trade, not a win.
Looks
Maple is pale cream, brightens a kitchen, and shows the food. Walnut is deep chocolate with purple and amber undertones, and its end grain figure is the best in the shop. Maple shows beet and turmeric stains more readily; walnut hides nearly everything.
Cleanliness
Both are closed-pore woods, which is why they're cutting board staples. Wood in general beats plastic here — studies going back to the UC Davis work of the 1990s found bacteria drawn down into wood do not survive, while knife-scarred plastic holds them. Walnut heartwood contains juglone, which gives it mild natural antimicrobial properties; maple's density and tight pores accomplish much the same thing. Keep either clean and oiled and both are safe for everything, raw meat included.
Price
Walnut lumber costs more than maple — expect the walnut board to run $40–60 above the equivalent maple. Hickory typically comes in below both if budget leads.
Pick maple if you want the classic butcher block look, the brightest surface, maximum dent resistance, or the lower price.
Pick walnut if you want the showpiece, the most knife-friendly surface, and stain camouflage — and the board will live on the counter where people see it.
Either way, construction matters more than species: our boards are all end grain, so both the walnut and the maple self-heal and stay smooth for decades.
