The 5.5" 15 Teeth KASHO Green Series Texturizers are designed with a semi-offset handle and tension adjustable screw with an integrated ball bearing. The teeth are shaped by an erosion technique that forms the same angle on each tooth. When the teeth meet the cutting edge of the convex blade, the cut is clean not jaggered. In addition, the spacing between the teeth are tapered towards the inside of the teeth blade. This prevents hair from tangling as you pull the shears away. The convex blades are mirror polished for smooth, quiet operation. The 15 Teeth thinning shear is great for bulk thinning.
