13K/TG Kirkland Periodontal Chisel

The 13K/TG Kirkland Periodontal Chisel (Article# LS1-335) is a double-ended instrument with two distinct working ends — a curved 13K blade measuring 3.3 mm wide and a straight TG blade measuring 3.2 mm wide — each carrying a sharp inward-facing cutting edge. The straight end activates on a push stroke, while the curved end activates on a pull stroke, giving the clinician two directional cutting options from a single instrument without a tray exchange. 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.

The combination of push and pull stroke capability on the 13K/TG Kirkland Chisel directly addresses the directional limitation of single-action chisels — the straight TG end removes bone on the forward push, and the curved 13K end recontours the crestal margin on the return pull. Both blades carry inner-bevel cutting edges that direct bone removal toward the tooth rather than away from it, maintaining controlled tissue removal throughout the osseous surgery sequence. The stainless-steel body tolerates autoclave sterilization at 134°C without blade distortion or edge degradation across extended clinical cycles.

Periodontists use the 13K/TG Kirkland Periodontal Chisel during osseous resective surgery and osteoplasty to remove alveolar bone ledges and recontour bone architecture toward a more physiological form. The Periodontal chisel “Kirkland” #13K/TG | F-LINE design covers both anterior and posterior sites — the narrow 3.2 mm TG end suits tight anterior embrasures while the curved 13K end handles posterior crestal recontouring.

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

What is the primary use of the 13K/TG chisel?
It is a double-ended surgical instrument used to recontour periodontal bone and remove remaining tooth fibers or tough deposits during periodontal surgery.
