1) I don't mind telling anyone about a lake, I'm not one of those to keep it to myself but it's Smurfy's lake so I feel like I should let him tell you if he desires.
2) I was behind the camera, who do you think took the picture?
I took the blades back off then buffed them clean with a dremel, oiled them, and touched them up with a lazer hand sharpener. Not sure if a guy can exchange since they aren't flat.
Added some pics so you can see the curve in them. I think they must be a "jet" blade.
