Sapphire Knife Blades and Handles
|
|
| Diamond knife quality at a fraction of the price The sapphire knife is a precision cutting instrument for use in ophthalmic, neurologic and plastic surgery research procedures. It provides a superb cut far exceeding that of a finely honed steel knife. Under magnification of the optical microscope, even the best steel blade appears saw-toothed with metal flakes loosely attached to the cutting edge. Such a blade will produce a rough cut and damage to tissue. In contrast, the blades of WPI's sapphire knife can be polished to a far greater smoothness (less than 0.05 µm RMS). An incision made by a sapphire knife results in significantly less damage than a conventional steel knife and no metal particles are left behind in the tissue, so wounds heal faster with less scaring. |
