>Pocket bellows
This shit was such a gamechanger for me. I live in a climate where it's damp and humid 8 months of the year. Being able to ventilate and get a fire going with even really damp wood is pretty manageable with a tool like this. Could use it as a straw too, why not?
What's your knickknack that you see rarely recommended here?
