I tried tvs and stuff like that but didn't get any... I tried some more wooden blocks, and after a while I got some wires. Only the claw hammer seems to work for that.
Thanks anyway for your suggestion !
I have another question : I can't figure out where I am supposed to craft the screwdriver... I got the skill, crafted the mold, got the materials, now what ? I Tried workbench, forge, anvil... The description in skill category says "Craft it on the metal working bench" but I don't see this metal working bench anywhere
