Researchers have created wood materials 23 times harder than typical woods.

Researchers from the University of Maryland have created wood materials 23 times harder than typical woods. They created a wooden knife and wooden nails using the hardened wood and found that the performance of both matched or exceeded that of their steel counterparts. The wooden nails were as sharp as commercial steel nails but with the added bonus of being rust-resistant. All of the main raw materials used to create the hardened wood are abundant and low cost.
