2 Fedi Periodontal Chisel
Double-ended periodontal chisel with angled straight blades for precise interproximal tissue excision and secondary sulcular incisions.
Key Features:
• Double-ended design with opposing straight blades
• Blade width approximately 2.3 mm for interproximal access
• Semi-circular cutting edges on both sides of each blade
• Blade angulation set at 15° to terminal shank for controlled engagement
• Active cutting edges operate simultaneously on push stroke
• Round ringed knurled handle, overall length 165 mm (6.5 in)
• Surgical-grade stainless steel construction, autoclavable at 134°C
• Suitable for gingivectomy, sulcular incisions, and fiber attachment removal
The 2 Fedi Periodontal Chisel (Article# LS1-338) is a double-ended instrument with opposing straight blades, each 2.3 mm wide with semi-circular cutting edges on both sides, set at a 15-degree angle to the terminal shank face. The 15-degree blade angulation differentiates the #2 from the #1 variant — which uses a 10-degree set — positioning the cutting edge at a slightly steeper angle against the interproximal tissue base. The round ringed knurled handle is machined from surgical-grade stainless steel, measuring 165 mm (6.5 inches) overall, with the balance point centered at mid-handle for stable push and pull stroke control.
The increased 15-degree blade angle on the Fedi Chisel #2 directs the cutting edge more acutely into the interproximal tissue base, reducing the hand repositioning required when transitioning from anterior to posterior sextant access compared to the flatter #1 geometry. Both lateral semi-circular cutting edges remain active simultaneously on the push stroke, severing interproximal tissue buccolingually through the col area in a single pass. The stainless-steel body tolerates repeated autoclave sterilization at 134°C without blade angle distortion or cutting-edge degradation.
Periodontists use the 2 Fedi Periodontal Chisel during gingivectomy, modified Widman flap, and osseous resective procedures to excise interproximal tissue, execute secondary sulcular incisions, and remove remaining fiber attachments from root surfaces. The Fedi periodontal chisel #2 activates with short horizontal push strokes directed buccolingually through open embrasures, with clinicians applying controlled wrist-level force to sever the col tissue cleanly before tissue removal with surgical forceps.
Leader Surgical builds instruments that work the same on day one as they do after two years of daily sterilization — and every chisel in this range is a straightforward example of that manufacturing standard in practice.
What is the primary function of the Periodontal 2 Fedi Chisel?
It is used for making secondary sulcular incisions in flap procedures and for recontouring soft tissue or excising interproximal tissue.
