Once tool/weapon repair "goes live", can we also get round shields repairable? as in recover shield boss from a worn/beat shield and use boards to fix it. I'd think using "capped tier below the tier of boards" for the shield fixing/rebuilding.
i.e. decent boards to result in rough roundshield, fine boards result in decent roundshield and perfect boards result in fine roundshield. At MOST!
Should use *CARPENTRY* and preferably, have a Driik/Reemi/Sarto Craftsman give quest for XYZ (finding their missing kid?, fetching herbal concoction from a sage faraway for their elderly parent? Killing an invading Njerpez in region pointed like in wounded adventurer/bird thief/animal in forest cover?) and as reward teach the character how to fit the boards and attach a reclaimed shield boss. Having a roundshield also required.
Fitting boards should benefit of using hewing hatchet/broad axe* for straight, flush edges.
*I'll type that suggestion next...

Axe hafts and spear shafts
