These oscillating knives for the wheel hoes are purchased separately. For one-pass weeding, choose the size that is 1" less than the space between plants. On the Professional model, two offset knives can be used for wide aisles or two aisles at once, but only with the single-point knives. Use offset knives next to fences and under wires.
