The 65 cm Flower blade from Schrockenfux in Austria is a good all-round blade. Faster over the ground than the 55 cm blade and better than the 75cm black blade around the trees. A good blade for someone who wants only one blade.
I call it the 'Orchard' blade. Good for clearing around the stems of young fruit trees and reasonably fast at mowing the rows between.
"Flower" is the name given to these gold blades by the factory. Some call the Flower blades: "Ditch" blades".
