I have the push lawnmower from HSN, and with much use it has gotten dull, I used sharpner on the blades, and wow, I was pushing again in 5 minutes, blades cut better than when the mower was new! I went around the house and garge looking for things to sharpen, this is definately a winner, not does it work well, it is a very good quality, it should last a long long time, and u get two of them to boot!!
