If such a beautifully packaged the new blade and black shiny smiles, everything seems fine. Unfortunately not, because the durability of the product is considered only mediocre. I cut regularly (1x per week in summer) a grassy area of approximately 500 square meters and had to find that the average after three or four months was worse again. When watching the knife then also clear signs of use in the form of small edges and less sharpness came to light, although I went neither stones nor have very tall grass mowed. Therefore only 3 stars. Delivery was not particularly fast, but for a grass knife still in order.
