Proto J100 Screwdriver Angled View

There are an abundance of keychain-sized screwdrivers. I found this one, by Proto, model J100 – it looks pretty durable and is made in the USA.

Slotted?

There are lots of people who use a slotted screwdriver, and I can see some potential applications for this one.

Are you an electrician during a final walkthrough, and the homeowner asks why the light switch and outlet cover screws aren’t aligned? Whip this out and give them a turn.

Camera grip equipment and things like tripod quick release plates tend to have a lot of specialty screws with slotted recesses.

I’m sure there are other potential uses.

Proto J100 Screwdriver

According to online product descriptions, the keychain-sized screwdriver has a 3/16″ tip and is 2-1/4″ long.

Proto is Stanley Black & Decker’s industrial tools brand, and so I’m sure it’s good. It’s priced at around $12.

I’m not rushing to buy one, buy I’m glad I found it.
