V-Tooth
Description
V-tooth thinning scissors use sharp, angled tips that cut hair cleanly for precise bulk removal. Learn how the V profile compares to U-tooth and mushroom designs.
V-Tooth (Vトゥース)
Quick look
- What it is: V-shaped grooves cut between straight teeth on a thinning blade
- Grip strength: High; strong bite that holds hair firmly during the cut
- Best for: Thick, coarse hair that needs reliable weight removal
- Heritage: The traditional Japanese thinning tooth design and the most common configuration worldwide
Why it matters
The V-tooth is the standard tooth profile for thinning and texturizing shears. Each tooth has a V-shaped notch cut between it and the next, creating a comb-like pattern. When the blades close, hair caught between the teeth is cut. Hair sitting in the V-shaped gaps passes through uncut. Simple, predictable, effective.
The V-shape gives this tooth type its defining characteristic: strong grip. The angled walls of each notch channel hair inward toward the cutting point, preventing strands from sliding out before the blades close. This makes V-tooth thinners especially reliable on thick, coarse, or resistant hair where softer tooth profiles might let strands escape.
Cut rate and tooth count
V-tooth thinners come in a wide range of tooth counts. Fewer teeth (5 to 15) produce aggressive texture with high cut rates of 30% to 70%. Mid-range counts (20 to 35) handle standard thinning and blending at 15% to 35%. Fine-tooth models (38 to 46 teeth) remove just 5% to 15% per pass for subtle, seamless blending.
Practical considerations
The strong bite of V-teeth can leave visible cut marks if the scissors are used carelessly on fine hair. The sharp transition between cut and uncut strands shows more than it would with a mushroom tooth or step comb profile. For thick hair, this is rarely an issue. For fine or silky hair, consider a softer tooth type or use the V-tooth thinner deeper in the interior of the cut where marks won’t be visible.

Frequently Asked Questions
Each tooth has a V-shaped notch cut between it and the next, and the angled walls of each notch channel hair inward toward the cutting point. This shape prevents strands from sliding out before the blades close, which is the mechanical reason V-teeth hold hair reliably on thick, coarse, or resistant sections where softer tooth profiles would let strands escape. The same grip strength that makes V-teeth dominant on heavy hair is what gives them higher marking risk on fine ends.
V-tooth count correlates directly to aggressiveness. Low counts of 5 to 15 teeth produce aggressive texture at cut rates of 30 to 70%. Mid-range counts of 20 to 35 handle standard thinning and blending at 15 to 35%. Fine-tooth V-models with 38 to 46 teeth remove just 5 to 15% per pass for subtle seamless blending. The V geometry carries through the entire range — it is the count and spacing that shift the rate, not the underlying tooth shape.
On fine or silky hair where marks would be visible. The strong bite that makes V-teeth excellent for thick hair also creates a sharp transition between cut and uncut strands that shows up as visible lines on delicate hair. For fine-hair clients use a mushroom tooth or step comb profile for surface work, or reserve the V-tooth for the deeper interior of the cut where any lines stay hidden under longer hair on top.
