I just won a new Minelab Digger from the contest and was admiring it last night. All I have ever used before this was a garden spade that I bought at Lowe's. I have always sharpened the spades I use and find that they work so much better and are less work to use when sharp. The Minelab Digger is not as dull as the spades I have had and has a nice slick coating ,like powder coating on it, which makes me reluctant to sharpen it as i would be exposing uncoated metal. How many of you use them as they are (Lesche, Minelab or similar) and how many like to sharpen the cutting edge (not the point).
