9 Goldman Fox Periodontal Knife
Double-ended periodontal knife with dual blade geometries for posterior access and interdental tissue debridement during gingivectomy procedures.
Key Features:
• Double-ended design with spear-point and elongated sickle blade
• Spear-point blade angled for posterior mandibular access
• Sickle blade for interdental tissue cutting and debridement
• Dual blade configuration reduces need for instrument switching
• Angulated working ends improve reach in distal molar regions
• Sharp cutting edges maintain efficiency across both blade types
• Round ringed knurled handle for secure grip during wet procedures
• Surgical-grade stainless steel construction, autoclavable at 134°C
The 9 Goldman Fox Periodontal Knife is a double-ended periodontal soft tissue instrument built from surgical-grade stainless steel, featuring two functionally distinct blade types on opposing ends. One end carries a combination spear-pointed blade angled for approach from the posterior direction in the mandibular region, while the other carries a modified elongated sickle blade for interdental tissue debridement. This dual-blade configuration makes figure 9 unique within the Goldman-Fox series — no other figure pairs a posterior approach blade with a sickle-style interdental cutter on a single instrument. The round, ringed knurled handle provides a firm, non-slip grip for controlled directional blade delivery.
The 9 Goldman-Fox Knife is the only figure in the series combining two different blade geometries, eliminating the need to switch instruments during the same surgical sequence. The spear-pointed end is angled to enter from the distal aspect of the mandibular arch — particularly useful behind the last molar — while the elongated sickle end sweeps through narrow interdental columns to sever tissue and remove soft debris. Both blades maintain edge geometry through repeated autoclave sterilization cycles.
Periodontists use the 9 Goldman Fox Periodontal Knife during mandibular gingivectomy and distal wedge procedures. The surgeon approaches the distal mandibular molar region from posterior, inserting the spear-pointed end behind the last molar to incise the retromolar pad tissue. The sickle blade end then enters interdental spaces along the arch to debride remaining papillary attachments after the initial excision strokes.
The Perio Knife Goldman-Fox N.9 brings genuine dual-function versatility to posterior soft tissue surgery. Leader Surgical produces this instrument to consistent dual-blade geometry, verified stainless steel composition, and sterilization-safe finishing standards.
What materials are used in its construction?
Most high-quality versions, such as those from ProDentUSA and Lenox Instruments, are handcrafted from 440A stainless steel or surgical-grade German stainless steel to ensure corrosion resistance and edge retention.
