A uterine curette is primarily made by Impression-die Forging. Impression-die (closed-die) forging squeezes hot metal into a shaped die cavity so the grain follows the form. It gives high strength and good repeatability. Below is the full route to make a uterine curette, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a uterine curette is made
The usual route, raw material to finished part. The amber step is where the uterine curette gets its basic shape.
Material
Cut martensitic stainless bar (420 or 410 grade) sized for the uterine curette.
Die forging
Heat and drop-forge the blank, so the grain follows the form and gives the strength.
Tooling High (dies) Tolerance ±0.25 to 1mm Lead 8 to 20 weeks
Trimming
Trim the flash and pierce the rings, bows or finger holes.
Milling the pattern
Mill the shank and working end, and cut the serrations, teeth, ratchet or cutting edge.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Heat treatment
Harden and temper the working ends for wear resistance and spring.
Tooling n/a Tolerance can distort Lead days
Grinding and polishing
Grind the profile and satin or mirror polish the uterine curette.
Tooling Low (wheel) Tolerance ±0.002 to 0.02mm Lead days
Passivation
Passivate or electropolish to restore the corrosion-resistant chromium-oxide layer.
Tooling Low Tolerance removes microns Lead days
Marking and inspection
Laser-mark, ultrasonic clean, then inspect the action, alignment, sharpness and finish.

What a uterine curette should cost
Best strength and fatigue (grain follows the part). The die (6k to 20k USD) is why part one is expensive.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a uterine curette at your volume, in your currency, are in the dossier.
