I've read the series and it's great except the main characters are horrible people worse than the villain.

I look forward to being able to eat steak on airplanes again.

Lord Foul is basically the manifestation of the characters' self loathing.

How strong are these?  The video showed a guy cutting a buttery soft steak, very gingerly.

Another video in a link from that article showed a "wooden nail" being hammered into 3 thin pieces of wood (total thickness of maybe half an inch) - the person was basically just lightly tap-tap-tapping the nail with a tiny hammer, and took a good 2 minutes to drive the nail through.  Sure, that's cool, but what happens if you apply some serious force, like with a 1 lb hammer?

Word salad is still salad and I will not eat of it.

Superwood is very, very cool. I want to make some specifically to make knives, but I'm having trouble with the last step - 5 MPa pressure at 100C. Considered using the bottle jack, then considered what would happen to it at that temperature. Next stop is the local University's Mechanical and Materials Engineering department for suggestions.

... the idea of wooden Threat Level III armor is also kinda cool.

My brain goes to guitars or skateboards made out of hardened wood.

Think structural steel replacement for building trades. Cheap armor.

There are various types of s strengths of of things like metal.

A basic rule is that the harder a metal is made the more it can hold an edge and be wear resistant. But this hardness comes at the cost of brittleness.
Maybe the didn't give a hefty whack to the nail because it would crack or shatter.

Making it essentially useless as a nail for most applications
