Why Designers Add Extra Features
Tool design is usually about solving problems.
A good tool isn't just something that performs one action.
It should ideally be comfortable, durable, efficient, and safe to use.
Manufacturers may add small features to accomplish these goals.
For example, a hole could make storage easier.
A textured section could improve grip.
A curved edge could help position the tool.
A notch could provide leverage.
A rotating component could allow greater flexibility.
These details can be easy to overlook because they are not always the primary reason people buy the product.
But they can still be useful.
Look at Your Toolbox
This is where the story gets interesting.
Take a few minutes and look through your toolbox.
Don't focus only on the obvious tools.
Pick up a screwdriver.
Look closely at the handle.
Examine the shaft.
Check the shape of the tip.
Now look at a pair of pliers.
