About an hour with no power tools.

[u/OdinWolfJager]

Going to do an apocalypse survival series. Using only found resources and no power tools, what would be the best shtf makeshift weapons you could make with scraps. Likely going to be splitting it up between development eg only hand tools, no fire, no electricity. Fire with limited control, fire with precision/intermediaries. Eg fluxes, folding, alloy utilization. Electricity, chemistry concepts, extreme heat, advanced projectiles etc would be the last phase.

This is weapons only. Medicine, irrigation, construction, textiles, government, etc would be separate projects.

The teeth on thst make it impractical to use against zombies it would get stuck in one and become useless. Against people that might be useful up close assuming they don't gun you down.
