Tunnelling Knife Fig. 2

The Tunneling Knife Fig. 2 (LS1-370) is a double-ended periodontal microsurgery instrument with two asymmetrically curved working ends — one end carrying a shallower curve and the opposing end angling more acutely upward. The central handle features a knurled cylindrical grip with uniform ribbing across the full middle section and smooth tapered shanks transitioning toward both blade ends. The right working end shows a more pronounced upward blade angle than its counterpart, distinguishing this Fig. 2 design from the Fig. 1 variant. Full construction uses solid stainless steel throughout with a matte satin surface finish.

Each working end carries a thin, flat blade face with a smooth rounded toe for clean subperiosteal advancement through connective tissue. The asymmetric blade angles allow the surgeon to work from opposing approach directions within the same tissue tunnel without rotating the instrument body. The #2 Tunneling Knife blade geometry covers both the coronal and apical aspects of a subperiosteal pouch during a single procedural pass. Stainless steel construction tolerates repeated steam autoclave sterilization without blade curvature change or surface wear at the shank junctions.

Periodontists use the Tunneling Knife Fig. 2 as a companion instrument to the Fig. 1 knife during the tunnel technique for root coverage procedures. After the Fig. 1 establishes the initial subperiosteal corridor, the Fig. 2 blade reaches tunnel zones requiring a steeper approach angle — particularly the apical extent of the pouch and the papillary regions between adjacent teeth. This Instrument for Periodontal soft tissue grafting also aids graft stabilization by refining tunnel wall release before suturing.

Leader Surgical manufactures this knife with consistent blade curvature and shank angles held to the same dimensional standard across every production batch. Periodontal specialty clinics pair it with the Fig. 1 variant as a complete tunneling setup for multi-tooth recession correction procedures.

How does Fig. 2 differ from Fig. 1?
While Fig. 1 is often straighter for anterior teeth, Fig. 2 features a curved or angulated blade designed for the lower jaw and posterior (back) regions where access is more restricted.
