What is the difference between a float and a rasp?

Question

Both are used for filing wood and other materials.

Answer 1

Floats are similar to Rasps and Files, however: Floats have parallel teeth and they can be resharpened as many times as the thickness of the blade will allow. Rasps are generally coarse and cannot be resharpened. Files have angled ridges or teeth and cannot be resharpened.

A float is used to cut, flatten, and smooth (or float) key areas of wood by abrasion. There are two types of floats. There is edge float and the flat sided float. Edge floats resemble saw blades and are generally used to cut wedge slots in wood. Flat sided floats are more similar to a file or rasp but their cutting edges are a series of parallel teeth.
