A small electric/tester (insulated) screwdriver is a cheap multi-purpose tool.
From unentangling two fine necklace chains of my daughter, to cleaning salt deposits on faucet thread during a plumbing job. You will appreciate this small, light an inexpensive tool.
Yes, you can use the small screwdriver part of those pocket tools (like Atwood tools) or swiss army knife, but it is not insulated, nor can it reach deep enough in some cases.
The other day, my grand son wanted to watch TV in a chalet we have rented, and the external part of the ON/OFF button was broken. I inserted the small screwdriver tip and pushed the inner part in, and the TV was ON. Knife tip would have worked too, but I wouldn't take the risk of an electric shock.
