Twelve combination wrenches, sized 8 mm through 19 mm, drop-forged from chrome-vanadium steel and mirror-polished to resist rust and grime. The 15° head offset clears knuckles in tight spaces; the closed ring is 12-point so you can re-engage the fastener every 30°.
Stored in a roll-up canvas pouch — the kind that lives in your toolbox for a decade and only gets better with age.
