8 Goldman Fox Periodontal Knife
Double-ended periodontal knife with spear-point blades for precise interdental tissue severing following primary gingivectomy incisions.
Key Features:
• Double-ended design with opposing angulated spear-point blades
• Narrow tapered blades with cutting edges along both lateral margins
• Offset blade geometry for improved access to interproximal areas
• Designed for buccolingual severing of interdental papillary tissue
• Angulated ends allow mesial and distal access without repositioning
• Green-toned ringed knurled handle for secure grip in wet conditions
• Manufactured from 440A surgical-grade stainless steel
• Fully autoclavable with corrosion-resistant construction
The 8 Goldman Fox Periodontal Knife is a double-ended soft tissue instrument constructed from surgical-grade 440A stainless steel, featuring two sharp spear-pointed blades with an offset angulation on each working end. Unlike the oval-bladed figure 7, the figure 8 carries a narrow, tapered spear tip with cutting edges running along both sides, a geometry purpose-built for interdental penetration and buccolingual tissue severing after the primary incision. Both working ends are angled in opposing directions from the handle axis, giving the clinician access to mesial and distal interproximal sites from a single instrument. As visible in the image, the handle carries a green-toned ringed knurled barrel with a firm, non-slip surface for controlled blade delivery during fine interproximal strokes.
The Periodontal Knives Goldman-Fox 8 series sits within a family of 11 figures, each carrying a distinct blade form for a specific soft tissue task. Figure 8 follows the initial bevel incision made with the Goldman-Fox 7 — where the oval blade removes facial and lingual gingival walls — and enters the narrow interdental column to sever remaining papillary tissue connections buccolingually. The angulated blade offset reduces wrist deviation during posterior interproximal access, maintaining the tip’s trajectory without forcing handle movement into adjacent teeth.
Periodontists use the 8 Goldman Fox Periodontal Knife during gingivectomy procedures immediately after the primary external bevel incision. The surgeon inserts the spear tip interdentally and draws it buccolingually in a single decisive stroke to transect the interdental papilla at the base of the excised tissue tag, freeing it from adjacent tooth surfaces and completing the gingival excision in one pass.
The 8 Goldman-Fox Knife is an indispensable second step on every gingivectomy tray. Leader Surgical produces this instrument with consistent blade geometry, verified stainless steel composition, and sterilization-safe surface finishing.
Why is the blade angled?
The angulated blade is designed to provide easier handling and better access to difficult-to-reach interproximal areas within the oral cavity.
