Here is a pic of the new blade (it has a protective rubber coating over the teeth right now. Remove the rubber coating, but make sure to not place the blade on a metal surface. Our shop happens to use carbide blades, but it is a general rule to not place the blade on a metal surface to avoid dangers of chipping a blade. On that note, make sure to inspect the blade for any defects. If the blade is defective, DO NOT USE THE BLADE.
