NES-1866

7
The Goldman-Fox pattern covers several blade sizes within the same family, and the NES-1866 is the No. 7 variant, sized for interdental gingivectomy work where a mid-range blade width handles most routine cases without excess bulk.
What defines this size within the Goldman-Fox lineup:
Moderate blade width bridges the gap between the finer interdental knives and the broader facial-surface patterns
Sharp, angled cutting edge follows natural papilla contours during routine tissue trimming
Balanced enough for repeated fine strokes across several teeth without excessive wrist strain
Tip doubles as a quick diagnostic instrument for assessing tissue firmness before the first incision
Offered with a hollow handle at Ø 8mm or Ø 9.5mm, or a solid handle at Ø 6mm
Clinicians who stock the full Goldman-Fox range typically keep the No. 7 on hand as the default choice for standard gingivectomy cases, reserving the smaller and larger numbers in the series for tissue that calls for either extra precision or extra reach. It’s less specialized than the narrowest interdental knives but more controlled than the wider facial-surface blades.
Forged from surgical-grade stainless steel, the NES-1866 resists corrosion and holds its edge through repeated autoclave cycles. A practical mid-size option for periodontists building a complete Goldman-Fox knife set rather than relying on a single blade width for every case.
