11 Goldman-Fox Knife

The 11 Goldman-Fox Knife (Article# LS1-328) is a double-ended periodontal gingivectomy knife with two spear-pointed blades — both offset and carrying sharp cutting edges along both lateral margins — designed specifically for posterior interproximal access. The blade angulation on each working end mirrors the Goldman-Fox #8 geometry but with offset orientation, directing the spear tip into posterior embrasures without handle contact on adjacent teeth. The round ringed knurled handle is machined from surgical-grade stainless steel, measuring 165 mm (6.5 inches) overall, balancing consistently at mid-handle during push and buccolingual incision strokes.

The offset blade geometry on the Dental Goldman Fox Periodontal Knife 11 differentiates it from the straight-shank #8 — the angular offset repositions the spear tip closer to the posterior col area from the buccal approach without requiring the clinician to reposition hand or elbow. Both lateral cutting edges remain active simultaneously, severing interproximal tissue buccolingually on entry and withdrawal in a single stroke. The stainless-steel body withstands repeated autoclave sterilization at 134°C without blade deformation or cutting-edge degradation across clinical use cycles.

Periodontists use the 11 Goldman-Fox Knife during gingivectomy and gingivoplasty procedures as a secondary interproximal incision knife, activating it after the initial bevel incision to completely sever the posterior tissue tag through the col area. The Goldman Fox #11 is particularly useful on mandibular molar sites where the offset blade angle gives direct buccolingual access without the handle clearing the occlusal plane on neighboring posterior teeth.

Leader Surgical knows that the instruments clinicians use daily need to perform identically on the hundredth use as on the first — and every knife leaving this production line is built to that exact standard

What is the specific use for the “11” model?
It is a double-ended spear-point knife designed primarily for gingivectomy and gingivoplasty. Unlike the Goldman-Fox 8, the 11 model features offset blades, which are specifically angled to provide better access to the posterior (back) regions of the mouth and tight interdental spaces.
