There seems to be an obssession with steel tools here. Even now steel is so expensive that it is effectively not available to the world's poor, so they use alternative materials as they have done for millennia.

Wooden spade:

Wood and stone adze:

Wood and stone axe:

Wood and stone hammer:

And from my own collection of hand tools found within 30 metres of my house:

There's certain places in my creek bed where the recent currents have swept the sediment away leaving the local pebbles exposed. I expect the kids were sent to collect any handy-looking rocks every day, to give them something useful to do and keep them out of the kitchen while Mum gets on with the cooking.
These rocks include quartz, which when heated in the fire and then dropped into cold water, shatter to produce razor-sharp edges. They blunt very quickly but hey, there's always more quartz rocks.
Blocks of oysters bound in coral limestone can be found on the exposed coastal headlands, and carried inland like this one was.

The shells are very fragile, so this pointed tool could only have been used for very delicate work like painting dots on skin.

String is made from the bark on the ends of fig tree branches, soaked until the woody parts peel off from the fibre, then plaited multiple times, then dried - wet again before use, then dried in situ, and sealed with gum from Bloodwood.
Come on you guys, you're still thinking hi-tech, and want things to last more than 100 years. Start thinking primitive. There's going to be no TV, so what are you going to do round the campfire at night but hone your stone tools and plait string? - yeah, I know, play your electric guitar, power by solar panels and stored in lead-acid batteries.
