PLM Keychain 10mm Ratchet Wrench

Took this keychain ratchet to tighten a loose bolt on my car's battery terminal—the chrome plating is holding up nicely against grease. Fits right on my keys without adding bulk.

I've been reaching for this little ratchet wrench more than I expected—the chrome finish hasn't shown a single scratch after a month in my glove box. It's small enough to clip on my keys and actually saved me when I had to swap a battery on the roadside last week.

Didn't think a keychain wrench would actually get used this much, but the 10mm fits half the bolts on my bike. It's small enough to forget it's on my keys until I need it, and the ratchet action is smooth.
