NickVLThey probably would be, I have some of their utensils I received as gifts, if these boards are the same material, it's even harder than bamboo, which I am not a fan of, for knife edge preservation reasons.
If you won't want to splash on spendy wooden blocks, head into your nearest Kitchen/Restaurant supply store and pick up some Polypropylene boards, they are used in almost all professional kitchens for sanitary, edge retention and cost reasons.
NickVLI have 7 or 8 of these and I've used them for ~10 years. They're a wood fiber composite (Richlite) and they're no harder on my knife edges (carbon or stainless) than the maple edge grain board I also use. Ceramic edges will bite harder into these than you expect though.
NickVLYou can see the composition in the Amazon listings. The materials vary by color. For example, Nutmeg is "Crafted from 50% recycled cardboard composite," whatever that is.
NickVLThey are made out of paper and resin, then pressed and heated. It is actually a product called Richlite which sells the slab product to fabricators, mostly for countertops but also things like skate park ramps. Epicurean has been doing cutting boards out of it for years, you'll also find long strips of it in a lot of restaurant kitchens. Stuff is super tough, you can take a hammer to it, I'm not kidding I used to make and install counters out of this product.
