The 110mm or 125mm figure is the size of the round blade. A larger blade generally cuts through a taller stack of fabric, while a smaller one is lighter and easier to steer around curves. Choose by the thickness of the lay you cut most often.
Blades, the base plate, handle, wheels, switch and worm gear see the most use. Keep the blade sharp, oil the moving parts as the maker advises, and replace a worn gear before it damages the motor.
