Article is paywalled (and sci-hub doesn't work), but the Brinell hardness of 31 while certainly higher than normal hardwoods, is extremely soft compared to metal - softer than even wrought iron without a heat treat. I'm sure it could be made "sharper" than cheap cutlery, but that doesn't mean it will hold an edge well. I'd also be curious how recyclable the material remains after the chemical treatment required to densify it - I would suspect it's like e.g. MDF / plywood which is very bad environmentally due to the glues.
