I practice by BRF and mulch gardening, this requires to find many plants. I alerted my neighbors to provide me with their mowing and tree sizes remains. I did not look out. The original blade lasted only three uses due to introduction of gravel in these plants from neighbors. Be careful about the source of your plants, attention to pickup rake which we have not talked about. This is my personal experience. I tried to sharpen the grinder but impossible to find a good edge. So I returned the original blade to use the other side. No problem for now because I am careful what I put. I ordered the blade to have it help if the second side of my home had to dull blade. I received this blade in a blister Bosch. So I will use the confidence and only when the first is completely HS. It was delivered quickly.
