About the Freer Septum Knife
The Freer septum knife is a nasal knife best recognised by its small, D-shaped blade, a feature named in catalogue listings from Integra Miltex and other makers. Like other nasal knives, it is a one-piece stainless-steel instrument with a long, slender shaft between the handle and the blade.
Nasal knives are used to cut and dissect tissue inside the nose, including the septum, with blade shapes chosen to suit tasks such as submucous dissection or septal surgery. A related Freer-Ingal submucous knife also appears in registry listings.
Shaft length and blade size differ between manufacturers.
