Out of 11 blades tested:
Milwaukee Iron-carbide were the sharpest out of package but didn't hold up long.
Stanley Fatmax Carbide offered the best retained sharpness for the price.
Dewalt Carbide was the most expensive and 3rd least sharp out of the package. It held up best against the four types of media tested; cardboard, drywall, copper and soft steel staples. It was the overall winner.
