Correct option is D
A
bastard file is designed to
remove material faster due to its coarser teeth. It is commonly used for rough filing and shaping of metals, wood, or other materials. The spacing and size of the teeth allow for aggressive material removal compared to smoother files.
Smooth files have very fine teeth, which are used for
finishing operations rather than rough material removal.
They are slower at removing material compared to coarser files like bastard files.
A wood rasp file has very coarse, sharp, individual teeth that are specially designed for shaping
wood.
While it removes wood material quickly, it is not suitable for removing material from
metal or other harder materials.
