Rotary Blade Shapes
There are several different types of rotary blade shapes on the market. The original rotary blades (and the most common) have wedges in the center. Some of the new titanium (or premium) blades have a circle in the center. There is also an hourglass-shaped design. The BladeSaver Thread Cutter 3D is a "universal" design and it is compatible with all of these designs!
