Fresh oysters are tough to open if you don't know what you're doing, and you usually need a sturdy shucking knife. This method of opening from the front of the oyster can be done safely with a common paring knife.
We've show you how to safely shuck an oyster before (shucking from the back hinge), but this method is a little different. As Chef Grant Lee Crilly explains in this video from the ChefSteps YouTube channel, opening the oyster from the hinge is like prying open a door with a crowbar, and this method is more like picking the lock. Instead of shucking the oyster at the hinge, you take a simple paring knife and wiggle it in the front crack so you can sever the adductor muscle. It will pop open easily after that so you can serve it however you choose. Keep in mind, that this method may work better for certain varieties of oyster, with the back hinge method being better for others.
