I run Oregon rolled lift on all my mowers Fusion Blades .
I sharpen every day so only take off very little, With a Blade Sharpener. Before sharpener I would go threw 2 sets per mower each month, now I change out every month Still good blades I sell them to other guys that don't want to pay full price for blades
If you turn the edge a blue tint means you lost the hardness of the blade
