Knurling is a process of creating a rough, textured surface on a cylindrical object. It's usually found on things like:
* Hand tools: Screwdrivers, pliers, wrenches to improve grip.
* Machine parts: To improve the grip of a part on a shaft.
* Other objects: To improve the aesthetic appeal or create a non-slip surface.
The face of a hammer is typically smooth to provide a clean striking surface. This allows for a more controlled and consistent impact.
However, there are some specialized hammers that may have knurled faces. For example:
* Ball-peen hammers: These hammers have a rounded face and a peening face that may be knurled to help create a textured surface on metal.
* Rubber mallets: Some rubber mallets have a knurled face to improve grip and prevent slipping.
So, while not typical, there are some situations where a knurled face on a hammer can be useful.
