This is a heavier weight blade and at 80cm is longer than the Fux Styria Ditch blades. It’s length is useful if you need to do large amounts of rougher mowing but want to progress faster than the shorter length Styria blades allow.
The stronger and more experienced mower might use this blade when mowing reed, bracken or similar.
This is a strong blade and likely stronger then your snath!
It’s long length will exert more leverage on the snath so care should be taken to set the blade up carefully, watch out for obstacles and try to keep it sharp. A sharp blade will help you mow without excessive force. Excessive force can cause snath breakage if you unexpectedly hit an immovable obstacle.
