Pros: Ease of Use, Effectiveness, Overall Quality
Cons: None
Works great in narrow confines ... will it last?
I flip my lawnmower and touch up the blade edges with a fine diamond file each week. Takes only about 30 seconds, zip zip, as the blade doesn't get damaged on my lawn. Makes for a great cut. However, bought new mower with 2-blade mulching combo. Old diamond file too thick to get between the blades. Bought this EZE-Lap set (why not buy the set ... it's cost-effective.) Thin, flat file is working great. Time will tell if the file retains its diamond particles. (I'm using very light pressure when stroking across the blades.) Therefore, Durability is unknown at this time ... hence, the 4-star rating at this time.
