There are wrenches that are used to get into tight spaces that are just flat pieces of metal with a hexagonal hole cut out of them. Often they come with things like table saws and are used to move the arbor nut and change the blade.
Is there are a name for this type of wrench?
While I agree that when applied to bicycle maintenance these are called "cone wrenches", in general they're simply "thin open-end wrenches" or "tight-clearance wrenches".
These are often used in bicycle maintenance, because two nuts are often used to lock the bike axles.
The tool is called a cone wrench, and good ones are not cheap.
For example, this is a $75 set. Cheap sets are $20 and will round out upon application of torque
If it is the method of manufacture that you want to specify, then it is 'stamped' tools, as opposed to 'forged' or 'drop forged', or 'cast' or 'die cast'.
Generally stamped tools are cheaper. They have sharper edges which are less comfortable to use, and the jaws of the spanner are more prone to straightening out or rounding.
Stamped tools are cut like a cookie from a flat sheet of metal. Cast tools have molten metal poured into a mould of the correct shape. Forging means getting a piece of solid metal and hammering / pressing it into a mould of the final shape.
I agree with cheap that was my first thought.
They are usually open end wrenches with the open end In some cases they are combination one end open one end closed with 6+ sides
In the case of a skill saw those are a bit thicker but still cheap I have the proper sized combination wrench attached to my power saws in my shop with a magnet. Yes even if they were all 3/4 I would have a wrench on each one just easier having a heavy tool for me even routers I pack wrenches in their boxes.

They often come included with flat-pack furniture and cheap tools. They're admittedly hard to find because they're meant to be used once and discarded. Buy a small desk from Ikea and you should get one, or just pop into the service desk there and let em know you're missing one and they will help you out.
They're common at hoarder estate sales as well.
