This French stone is for use in the field on both ditch and grass blades. It is more suited to the finer edge needed on a grass blade then La Bergamasca whilst still being easily effective for a beginner.
This stone may effectively meet all your sharpening needs. However, as your sharpening / peening skills improve you may wish to progress to a Rozsutec stone which will give a finer edge and, as it will wear the edge more slowly, increase the time the blade will function well before needing peening again.
Grit – approx 1000
