Periodontal knives are the precision instruments that define clean incision lines, controlled tissue removal, and predictable flap outcomes in soft tissue surgery. This guide covers the major periodontal knife families — Goldman Fox, Orban, Kirkland, Sanders, Reddy, and the Siyah series — with selection criteria for gingivectomy, flap procedures, crown lengthening, and connective tissue grafting at Canadian dental practices.
As of April 2026, periodontal surgical procedures remain among the most technique-sensitive services dental professionals perform. Whether you are executing a straightforward gingivectomy or a complex tunnelling graft in your Toronto or GTA practice, the knife you choose directly determines incision precision, tissue trauma, and healing outcomes. EBIKO Dental carries a comprehensive range of periodontal knives designed for every soft tissue application — from classic designs that have proven themselves over decades to the enhanced-grip Siyah series built for modern ergonomic demands.
Understanding Periodontal Knife Categories
Periodontal knives fall into two broad functional categories: those designed for external incisions (gingivectomy and flap access) and those designed for interproximal and intrasulcular work. Selecting the right instrument starts with understanding which category your procedure requires.
External Incision Knives
These instruments create primary incision lines through keratinized and non-keratinized tissue. They feature larger, more robust blades designed for controlled sweeping cuts along the gingival margin or through the attached gingiva.
Interproximal and Intrasulcular Knives
These narrower instruments access tight interproximal spaces where standard blades cannot reach. They are essential for completing gingivectomy incisions between teeth and for releasing interdental papillae during flap procedures.
Goldman Fox Periodontal Knives
The Goldman Fox design is the workhorse of periodontal surgery. Its broad, kidney-shaped blade provides a stable cutting platform for gingivectomy incisions along the facial and lingual surfaces. The blade geometry allows the clinician to establish the correct 45-degree bevel angle that promotes rapid epithelial healing.
EBIKO Dental offers the 11 Goldman Fox Periodontal Knife in both the standard surgical finish and the 11 Siyah Goldman Fox Periodontal Knife with an enhanced black titanium coating that reduces glare under operatory lighting while improving surface hardness.
Pro Tip: When performing a gingivectomy with a Goldman Fox knife, mark your bleeding points with a pocket marker first, then connect the dots with a continuous sweeping incision at a 45-degree angle to the tooth surface. This creates the proper scalloped architecture for predictable healing.
Kirkland Periodontal Knives
The Kirkland knife features a heart-shaped or kidney-shaped blade that is narrower than the Goldman Fox, making it more versatile for both primary incisions and secondary trimming. The 15K/16K Kirkland Periodontal Knife is a double-ended instrument with mirror-image blades, allowing you to work on both the right and left sides without switching instruments.
EBIKO Dental also carries the 15/16 Siyah Kirkland Periodontal Knife featuring the ergonomic Siyah handle with its textured grip pattern that reduces hand fatigue during lengthy surgical sessions.
The Kirkland design excels in crown lengthening procedures where precise tissue contouring around individual teeth is required. Its slightly narrower profile compared to the Goldman Fox gives the clinician more control in tight anatomical spaces.
Orban Periodontal Knives
The Orban knife is the go-to instrument for interproximal tissue removal. Its spear-shaped blade is specifically designed to slide between adjacent teeth and excise the interdental papilla during gingivectomy procedures. Without an Orban knife, completing the interproximal portions of a gingivectomy requires awkward blade angulation that risks damaging adjacent tooth structure.
The 1/2 Orban Periodontal Knife is available in the classic stainless steel finish, while the 1/2 Siyah Orban Periodontal Knife adds the non-reflective Siyah coating for improved visibility in the surgical field.
Pro Tip: Insert the Orban knife from the facial aspect, angling the blade towards the lingual, and use a single controlled push stroke to sever the interdental papilla. Avoid a sawing motion, which creates ragged tissue margins and delays healing by 3-5 days.
Sanders Periodontal Knives
The Sanders knife is designed for situations requiring a finer, more delicate incision than the Goldman Fox or Kirkland can provide. Its slim blade profile makes it ideal for internal bevel incisions during modified Widman flap procedures and for trimming thin tissue margins during free gingival graft procedures.
The 1/2 Sanders Periodontal Knife from EBIKO Dental provides a balanced double-ended design suitable for both right and left working sides.
Additional Periodontal Knife Designs
Solt Periodontal Knife
The 1/2 Solt Periodontal Knife offers a unique blade geometry optimized for sulcular incisions. Its design allows the clinician to maintain the blade within the gingival sulcus while creating a controlled internal bevel incision — a critical step in the modified Widman flap technique taught at most Canadian dental schools, including the University of Toronto Faculty of Dentistry.
Reddy Thin Periodontal Knife
The 1 Reddy Thin Periodontal Knife and 2 Reddy Thin Periodontal Knife feature an ultra-thin blade profile specifically designed for split-thickness flap dissection. When raising a partial-thickness flap for connective tissue harvesting from the palate, the Reddy knife allows precise separation of the epithelial layer from the underlying connective tissue.
USC Towner Periodontal Knife
The 19/20 USC Towner Periodontal Knife features a distinctive curved blade designed at the University of Southern California. It excels in distal wedge procedures and tuberosity reduction, where access is limited and the blade must follow curved anatomical contours.
Kramer Nevins Periodontal Knife
The 11 Kramer Nevins Periodontal Knife combines features of a gingivectomy knife and a tissue nipper. It is particularly useful for trimming excess tissue during implant uncovering procedures and second-stage implant surgery.
Tunnelling Knives for Minimally Invasive Grafting
Tunnelling techniques have transformed soft tissue grafting over the past decade, and EBIKO Dental carries dedicated tunnelling instruments for these increasingly popular procedures.
The #1 Tunnelling Knife and #2 Tunnelling Knife are designed to create a subperiosteal tunnel without releasing vertical incisions, preserving blood supply and reducing post-operative discomfort. The Siyah versions — #1 Siyah Tunneling Knife and #2 Siyah Tunneling Knife — add the ergonomic grip and non-reflective coating that the Siyah line is known for.
Pro Tip: When using tunnelling knives for a connective tissue graft, start your dissection at least one tooth mesial and one tooth distal to the recession defect. This extended tunnel allows passive positioning of the graft material without tension, which is the single most important factor for graft survival.
The Siyah Series Advantage
EBIKO Dental's Siyah series instruments feature a black titanium nitride (TiN) coating applied over surgical-grade stainless steel. This coating provides three practical advantages for periodontal surgery:
- Reduced glare — The matte black finish eliminates light reflection from overhead operatory lamps, improving visibility in the surgical field
- Increased surface hardness — The titanium nitride layer adds approximately 20% hardness compared to uncoated stainless steel, extending the working life of the cutting edge
- Ergonomic grip pattern — The Siyah handle features a textured surface that reduces rotational slippage, even when wearing wet surgical gloves
Infection Prevention and Control (IPAC) Considerations
All periodontal knives are classified as critical instruments under the Royal College of Dental Surgeons of Ontario (RCDSO) infection prevention and control (IPAC) guidelines because they penetrate soft tissue. They must be heat-sterilized using a steam autoclave after every use. The RCDSO mandates weekly biological monitoring (spore testing) of all sterilizers used for critical instruments.
EBIKO Dental's periodontal knives are manufactured from surgical-grade stainless steel that withstands repeated autoclave cycles at 134°C without degradation. The Siyah titanium nitride coating is autoclave-stable and will not chip or peel under standard sterilization parameters.
