13K/13KL Kirkland Periodontal Chisel
Double-ended periodontal chisel with curved blades for precise alveolar bone recontouring during osseous surgery and periodontal flap procedures.
Key Features:
• Double-ended design with curved working ends (13K and 13KL)
• Blade widths: 3.2 mm (13K) and 4.9 mm (13KL) for anterior and posterior use
• Inward-facing curved cutting edges for controlled pull stroke activation
• Straight terminal shanks direct blade along alveolar bone crest
• Round ringed knurled handle for stable grip and mid-handle balance
• Overall instrument length approximately 165 mm (6.5 in)
• Surgical-grade stainless steel construction, autoclavable at 134°C
• Suitable for osteoplasty, osseous recontouring, and fiber attachment removal
The 13K/13KL Kirkland Periodontal Chisel (Article# LS1-336) is a double-ended instrument with two curved working ends — the 13K measuring 3.2 mm wide and the 13KL measuring 4.9 mm wide — each carrying a sharp cutting edge along the inward-facing curved blade margin. Both blades mount on straight terminal shanks that direct the curved cutting edge against the alveolar bone crest during pull strokes. The round ringed knurled handle is machined from surgical-grade stainless steel, measuring 165 mm (6.5 inches) overall, balancing consistently at mid-handle throughout active pull stroke sequences.
The stepped blade width across both ends — 3.2 mm and 4.9 mm — allows the clinician to cover narrow anterior interproximal bone margins with the 13K end and wider posterior osseous ledges with the 13KL end from a single instrument. The inward-facing curved cutting edge activates exclusively on the pull stroke, drawing the blade coronally along the bone surface to recontour ledges and remove fiber attachments. The #13/13KL Surgical Chisel stainless steel body withstands autoclave sterilization at 134°C without blade curvature distortion or edge degradation across repeated clinical cycles.
Periodontists use the 13K/13KL Kirkland Periodontal Chisel during osseous resective surgery, osteoplasty, and modified Widman flap procedures to recontour alveolar bone architecture and remove remaining tooth fiber attachments from root surfaces. The 13K/13KL Kirkland Periodontal Chisel 13KL end is particularly suited for posterior distal molar sites where wider bone ledges require broader blade contact during pull stroke activation across the crestal bone margin.
Leader Surgical backs every instrument it produces with the same manufacturing discipline — consistent blade geometry, verified material composition, and dimensional accuracy that clinicians can count on tray after tray.
What do “13K” and “13KL” signify?
These designations refer to the two distinct, beveled tips angled for right and left side access within a single instrument.
