Sapphire Blades are a precise and durable solution for use in microsurgery, dissection, and related applications. Sapphire blades are created using a chemical process which forms an artificial sapphire. The sapphire has a hardness value of 9 on the Mohs hardness scale, slightly below the hardest mineral on earth, the diamond. This characteristic provides supreme durability and sharpness to the blade. The sapphire blade's ultra sharp edge creates fine and precise cuts that prevent tissue damage and promote faster healing with less scarring. The sapphire knife's ergonomic grip offers an easier grasp and is designed to be used with WPI's blades. The blade's chemical composition provides a durable edge that lasts longer than steel surgical instruments, saving costs for your practice. The blade's sharp point and transparent finish allows greater precision in hair restoration, ophthalmic microsurgery, or cosmetic procedures.
