Rather like a heavy duty nail file, this twin diamond file works in the same way but for the coarse sharpening and re-setting of old blades. Double sided, the 120 side eats through the steel to a new edge, then the 300 gives a crude finish before you move over to a whetstone to get a decent edge.

Can also be used to sharpen rough edges on mower blades.
