Mini Folding Bottle Opener Knife
Couldn't load pickup availability
Two jobs, one tiny tool. The Mini Folding Bottle Opener Knife is a 420 stainless folder that also cracks bottle caps, and it comes on a non-metal cord so you can hang it from keys, a backpack or a zipper pull. At about 20g it is the lightest kind of insurance against a sealed bottle or a stray bit of tape.
Folds Small, Carries Anywhere
The stainless blade is sized for light cutting, the folding frame keeps a point off your pocket lining, and the cord loop means the knife is never more than a tug away. Twenty grams is nothing in a bag, so you stop carrying it deliberately and start finding it exactly when you need it.
An Opener in the Same Hand
Rather than reaching for a separate opener, the knife itself pops caps, which keeps the picnic kit down to one item. The stainless body shrugs off moisture, so it is happy on a kayak trip or a campsite as well as a kitchen drawer.
