I'm sure. Some years ago I was out biking without tools, and needed to
adjust something. There happened to be a bike store nearby, and the
sheet metal wrenches were what I bought. I believe that they are made
thin to be as light as possible - intended to be carried along while
biking.

The thin wrenches used on bicycles are called "cone wrenches". They are
used to adjust wheel bearing races.
