Four Seasons Gardener, Eliot Coleman designed this model to make weeding easier while standing up. Designed for fast, easy removal of small, seedling-size weeds. The 7" standard model glides through the soil with less resistance than the replaceable blade model. The narrow model, with its 3 3/4" blade, gets into tighter spaces. Also good for thinning. The 70? blade/handle angle allows you to stand straight and use a thumbs-up grip. The blade runs parallel to the soil surface, and is in line with the handle, thus collinear. Thin blade with sharp edges cuts small weeds just below the surface without throwing soil onto small seedlings. Oiled ash handle. Overall length 5 1/2_. Swiss made.
