I'd argue tools, not power tools mind you, but hand tools would be at least on par with wood.
In you assume an actual catastrophe you have to assume infrastructure collapse as well and fuel is infrastructure. The best chainsaw on the market, consumer or otherwise, needs fuel.
If you assume solar/hydro are still operational, then some battery operated things might keep on for a while, depending on the length of the catastrophe, but eventually they polarize and go.
Hand tools and the skills to use and maintain them at a reasonable level would be very valuable.
I have a reasonable selection of wood working hand tools. Planes, chisels, saw etc. Also some basic blacksmithing tools. The good thing about blacksmithing is that you can make more tools (not very good ones, but better than nothing).
