Gently and effectively target thread-stage weeds right up to crop stems without damage. The low-profile head is perfect for working in low-growing crops like lettuce, and the contoured shape provides added strength. Thoughtfully designed by Johnny's to withstand the rigors of market gardening by using corrosion-resistant materials for years of use. Made from high-quality stainless steel with an 11-gauge stainless-steel wire. Hole in the stem allows the convenience of carrying on a clip (clip not included). Actual head width is 3.75", to cultivate between crops spaced at 4" apart. Patent pending. Handle required, sold separately (see #6785). NOTE: Not for rocky or heavy soils.
