Folding hex sets live in more jersey pockets and saddle bags than probably any other tool format. The Park Tool AWS-10 packs the five most commonly needed sizes into a single unit that opens like a pocket knife, with each wrench pivoting out from the handle when you need it. The fold-up design means no loose pieces rattling around and no digging through a tool roll to find the right size when you're standing on the side of the road.

The AWS-10 includes 1.5mm, 2mm, 2.5mm, 3mm, and 4mm hex wrenches, which covers the small fastener range you'll encounter on accessories, limit screws, and some cockpit components.
