the.com/adjustable wrench
The one tool that admits it doesn't know your bolt size and fixes it anyway.
means A wrench with a movable jaw that slides to grip bolts and nuts of different sizes, instead of needing one fixed-size tool per fastener.
from The adjustable wrench's design dates to the 1800s, when inventors on both sides of the Atlantic raced to solve the problem of carrying a dozen fixed wrenches for a dozen bolt sizes. In the US it's often called a 'Crescent wrench,' after the Crescent Tool Company, which popularized a sturdy version in the early 1900s — so thoroughly that the brand name became shorthand for the whole tool, the way 'Kleenex' did for tissues. In the UK, the comparable tool is called a 'spanner,' from a German-rooted word for a device that 'spans' or stretches across a gap.
