For your consideration, here is an Arnold Edger Blade no. AEB-159, 9 x 2 Inch. The packaging has some wear on it and a spot on the back of the package. I lifted up the plastic on a corner, the blade looks fine. There are instructions on the back. Item pictured is the actual item up for sale and comes from a non-smoking household. (203.57f-.12hc)
[Thanks for looking!]
