Ballenger Swivel Knives — Pattern and Clinical Use
The swivel mechanism is what makes this instrument distinctive: the blade rotates freely in its fork so it follows the plane of the cartilage as the knife is drawn through, cutting a smooth continuous strip rather than a series of chopped segments. That lets the surgeon remove a deviated section of septal cartilage in one controlled pass.
The swivel must rotate freely but without play. A stiff swivel forces the blade off the plane and produces a ragged cut; a loose one wanders. Blades are replaceable on most patterns.

Material, Finish and Quality Control
We forge Ballenger Swivel knives from AISI 420 martensitic stainless. The swivel is cycled to confirm it rotates freely without play, since a stiff or loose swivel produces a ragged rather than continuous cut. Each batch passes Rockwell hardness testing, dimensional checks on swivel rotation and play, and visual inspection under our ISO 13485 system before passivation and final finishing. Mirror and satin finishes are both available — satin is usually specified where glare under operating lights is a concern.
Who Sources Ballenger Swivel Knives From Surgical Star
Ballenger swivel knives sell to ENT surgical distributors for septal surgery trays, with replacement blades as an attached consumable line.
OEM, Certification and Ordering
Every Ballenger Swivel knives can be produced as a private-label line: your logo laser-marked on the shaft, your catalog numbers, and your own printed packaging, manufactured from your drawings or a reference sample. Production runs inside a documented ISO 13485 quality system, with CE marking under EU MDR 2017/745 and US FDA establishment registration behind it. Your shipment carries a certificate of conformity plus the ASTM F899 material certificate for the grade actually used.
Minimums stay deliberately low so a new brand can launch without a heavy first order, and pricing is quoted direct from the factory on volume tiers. Bulk production usually takes four to six weeks from sample approval, shipped DDP with export paperwork and HS codes handled. See how OEM & private label works →

Frequently Asked Questions
What does the swivel do?
It lets the blade rotate freely so it follows the plane of the cartilage as the knife is drawn through, cutting a smooth continuous strip.
Are blades replaceable?
On most patterns yes, which restores the cutting edge without replacing the instrument.
What happens if the swivel is stiff?
The blade is forced off the cartilage plane and the cut becomes ragged rather than continuous, which is why swivel action is the key quality check.
Can you manufacture these under our own brand?
Yes — full OEM and private label. We laser-mark your logo and catalog numbers, pack in your branded boxes, and work from your drawings, tech pack or a reference sample, with a pre-production sample approved before any bulk run.
