Abstract
A knife opener includes a pair of flared blades designed to cut spaced, but paired furrows. The knife opener is particularly well-suited for use in no-till or minimum-till agricultural operations primarily in conjunction with seed and/or fertilizer placement adjacent a soil cut-line generally in the direction of travel. In addition to being angled away from the main body of the knife, one of the blades is angled forward and the other blade is angled rearward. Seed and/or fertilizer dispensing receivers may be associated with each of the blades.
