Freer Nasal Knife — Membranous Septum Variant

Freer Nasal Knife — Membranous Septum Incision

This Freer variant has a longer straight blade for the deeper membranous-septum cut that converts the caudal columellar incision into a full hemitransfixion — the standard opening of a septoplasty after the caudal skin edge has been raised. The longer blade reaches the floor of the nasal cavity at the maxillary crest in a single stroke, completing the incision plane that defines both mucoperichondrial flaps.

Why a separate variant

A short angled knife is the wrong tool for the deeper membranous-septum extension because it forces multiple short cuts that leave ragged flap edges. The longer straight Freer blade completes the cut in one pass, the perichondrial planes open cleanly on both sides, and the Freer elevator that follows finds an established subperichondrial space rather than having to dig for it.

Build

Forged AISI 410, hollow-ground edge that holds a working sharpness through twenty caudal-to-floor strokes before resharpening, and a hexagonal handle that resists rotation in a glove wetted by topical adrenaline solution.
