Peet Nasal Rasp, Diamond Coated Rhinoplasty Finishing Rasp
$ 38.00
The Peet nasal rasp, listed in some catalogues as the Peet Cottle or the Peet Aufricht rasp, is a finishing instrument for rhinoplasty: it takes down the last small ridges of nasal bone and cartilage and smooths the bony dorsum once the heavier work is done. The diamond coated face abrades rather than bites, so a surgeon can shave a fraction of a millimeter at a time under light hand pressure instead of committing to a cut. It comes with four working faces, flat or convex and straight or curved, so the profile can be matched to the part of the dorsum being shaped.
Key Features
- Diamond coated working face for controlled abrasion under light pressure

- High quality medical grade stainless steel, fully autoclavable
- Three year replacement warranty against manufacturing defects
- Item code AO-07.03
What a Peet nasal rasp is
A rasp is the instrument that finishes a nose, not the one that reshapes it. By the time it comes out of the tray the osteotome has already been through the nasal bones and the hump has already come down; what is left is a surface, and a surface with ridges on it will show through thin skin for the rest of the patient’s life. The Peet nasal rasp exists for that last pass. Its face carries a bonded diamond grit instead of cut teeth, so it removes bone by abrasion, a few microns to a stroke, and leaves behind something closer to a sanded edge than a filed one.
Catalogues write the pattern three ways, Peet, Peet Cottle and Peet Aufricht, and all three are the same idea with a different face. Ours is offered with four of them, and the face is the only decision a buyer really has to make.
Key design features
The diamond coated face
Diamond grit is bonded onto the working surface rather than machined into it. That matters in two ways a surgeon feels immediately. The first is that the rasp does not catch: a toothed rasp wants to bite and skip, and on a thin nasal bone a skip is a fracture. The second is that the cut rate barely changes with pressure, so the instrument does the same thing on the tenth stroke as on the first and the surgeon can judge depth by counting passes.
Flat or convex
A flat face sits on a straight dorsal line and removes evenly across its whole width. A convex face stands proud in the middle, which is what you want when the bone underneath is hollow or when you are working the curve at the side of the dorsum rather than the ridge itself. The convex face also lets a surgeon feather an edge, because only part of the grit touches at any one time.
Straight or curved
Straight is for an open field and a direct line of pull. Curved lifts the working face away from the handle, which is what gets it up to the root through a small incision without the handle fouling the nostril rim.
The handle
Flat, wide and long enough to be held like a file rather than a pen. A finishing pass is pulled with the forearm, not pushed with the fingers, and a flat handle is what makes that stroke repeatable.
Which tip to order
These four are taken from this product’s own option list and are the four we stock. If you need a face that is not here, the two other Peet patterns carry different ones.
| Tip option | The face | When a surgeon picks it |
|---|---|---|
| Flat Straight | Flat grit face, in line with the handle | Straight dorsal reduction in an open field. The default, and what most rhinoplasty sets carry |
| Flat Curved | Flat grit face on a curved shank | The same flat pass, but reached through a small incision or worked up toward the root where a straight handle fouls the rim |
| Convex Straight | Grit face crowned along its length | Hollow or concave bone, and feathering the edge of a reduction so it disappears into the untouched bone beside it |
| Convex Curved | Crowned face on a curved shank | The awkward one: a hollow surface high on the dorsum. If you only buy one convex face, buy this |
Where it is used
It is a rhinoplasty instrument first, and the table below is in the order the requests actually come in to us.
| Procedure | What the rasp does there |
|---|---|
| Primary rhinoplasty, dorsal reduction | The finishing pass after the hump is down. Takes out the ridges the coarse rasp and the osteotome leave and blends the cut edges into the bone either side |
| Revision rhinoplasty | Smoothing a callus or a step left by earlier surgery. An abrasive face is safer here than a toothed one, because a rasp that cannot catch cannot lever |
| Septorhinoplasty | Dressing the bony septum and the edge of the nasal spine after the septal work is finished |
| Nasal fracture reduction | Smoothing a healed malunion where the bone has set in the wrong place and only the surface needs correcting |
| Facial and maxillofacial contouring | Small bony prominences elsewhere on the face where the skin is thin and a filed finish would show |
What it abrades, and what it must leave alone
A finishing rasp is defined as much by what it must not touch as by what it removes, and the periosteum is the tissue surgeons worry about.
| Tissue | What this rasp does with it |
|---|---|
| Nasal bone, bony dorsum | Abrades. This is the working tissue and the reason the instrument exists |
| Bony septum, nasal spine | Abrades. Short passes, because the bone is thinner here than it looks |
| Upper lateral cartilage | Touches only at the edge. Cartilage loads the grit and stops cutting, which is a warning rather than a failure |
| Periosteum and the soft tissue envelope | MUST BE LEFT ALONE. Work under a raised flap, and keep the grit face on bone rather than dragging it back across lifted tissue |
| Skin | Never. A diamond face will take skin off faster than it takes bone, which is the reason the stroke is always toward the surgeon and always under direct vision |
How it compares with the other finishing surfaces
Three abrasive surfaces turn up in a rhinoplasty tray and they are not interchangeable. This includes the case against buying this one.
| Surface | How it behaves | Where it belongs |
|---|---|---|
| Diamond coated, as here | Cuts by abrasion. Slow, smooth, will not catch, and the cut rate hardly changes with pressure | The finishing pass, and any pass over thin bone under thin skin |
| Tungsten carbide grit | Coarser and faster. Fewer strokes, rougher surface | Bulk reduction before the finish. Start here on a real hump and finish with the diamond face |
| Cut steel teeth | A true rasp. Fastest of the three and the only one that will clog with bone rather than load with it | Heavy bone, and work where the finish does not show |
| A bone file | Not a rasp at all. Removes by shearing along the length of the blade | Edges and margins, not surfaces. A file cannot follow a dorsal curve |
Materials and finish
Every Peet nasal rasp we make is cut from high quality medical grade stainless steel. The steel itself is made to a German specification. We do not publish a grade number, because the number on a certificate tells a surgeon nothing about how an abrasive face holds up after fifty autoclave cycles, and the answer to that is in the finish rather than in the alloy.
The grit is bonded to the face and the rest is passivated and satin finished, which keeps glare off the field. There is no plating to chip and nothing brazed that can let go. What wears out on any diamond coated instrument is the grit: the face feels smoother, not rougher, as it ages, and a face that has gone smooth has stopped cutting. That is the moment to replace it.
Caring for it
Rinse it under running water the moment the case is over, before blood and bone dust dry in the grit. Dried bone paste in a diamond face is the single thing that kills these instruments early, and once it has set hard no ultrasonic bath will lift it all out.
Then a soft nylon brush along the face, never across it and never a wire brush. Enzymatic cleaner, ultrasonic cycle, deionized water rinse, dry fully, autoclave at 134 degrees Celsius. Store it so the face touches nothing, because the grit marks whatever it rubs against and whatever it rubs against polishes the grit.
Ordering and wholesale
The Peet nasal rasp is made in our own workshop and sold direct, which is why the price sits where it does against the catalogue houses. Order one for a single set, or in quantity for a hospital list or a distributor line; we do OEM work under your own brand and your own item numbers, and we will hold a run to your pattern rather than ours if you send a sample. Stock items ship from our own workshop. Backorder items take 10 to 12 working days to make. Every instrument carries a three year replacement warranty against manufacturing defects. Production is controlled under an ISO 13485 quality management system.
Frequently asked questions
What is a Peet nasal rasp used for?
Finishing the bony dorsum in rhinoplasty. It comes out after the hump is reduced, and its job is to turn the surface left by an osteotome or a coarse rasp into one that will not show through the skin. It is not a reduction instrument.
What does the diamond coating on a Peet rasp do?
It changes the instrument from one that cuts to one that abrades. Bonded grit takes off a few microns a stroke, will not catch and skip on thin bone, and removes at roughly the same rate however hard you press, so depth can be judged by counting passes instead of by feel. The trade is speed: a diamond face is slower than carbide grit and much slower than cut teeth.
Is it a rasp or a raspatory?
A rasp, and the two words are not the same instrument even though catalogues mix them freely. A rasp removes bone from a surface. A raspatory lifts periosteum off bone and removes nothing. If what you need is the lifting instrument, look at the raspatories in the same category rather than at this page.
Which way does a Peet nasal rasp cut?
On the pull. The face is worked toward the surgeon, and on a curved shank the stroke follows the curve rather than fighting it. Our four tip options are flat or convex and straight or curved; we do not list separate forward cutting and backward cutting versions of this pattern, so if you need a dedicated push cutting rasp, that is a different instrument in the same category.
Which instruments go with it in a rhinoplasty set?
A nasal osteotome for the lateral and medial cuts, a coarse tungsten carbide rasp for the bulk of the hump, an elevator to raise the flap, and a raspatory for the periosteum. This rasp is the last bone instrument to touch the nose.
